Manual of sexual education

Everyone has a right of love. Once you succeed to get a sexual partner, the road to sexual pleasure may look long, sometimes endless.

This article explains the fondamentals of sexual education. Thanks to it, the key to sexual pleasure is in your hands.

I wish you a nice reading.

What does'nt kill us makes us stronger

A pseudo phiilosopher has said that the hammer forges the iron but breaks the glass.

Even from terrible hardship, it's possible to heal. The love from family, a man or a woman can greatly contribute to it.

Allow me to be a little childish and and present you to a creature that I like.

This is Skarmory, mix of scar and armory. It grows in brambles and develops a body made of steel.

Let us inspire by Skarmory and overcome the crisis to build an utopia on the ruins of the old world.

And you know what ? One day, Skarmory will learn to fly.

Keep it stupid, affectuous

During all those years, I've been struggling to find love in a time where the logical people like me have a harsdhip to find it. Officially, 80 % of Asperger men are alone.

Sometimes we should forget about the troubles of life by escaping with little pleasures : watching an amazing movie, playing a good old Mario Kart game, cooking carbonara... From little pleasure to little pleasure, the door of happiness tends to open, and once open wide, you can succeed the best things in life : living in an autonomous house, making a family, travelling far...

My pursuit of love and happiness is leading me to Spain. I get tired of empathy and am looking for optimism :-) .

So, let's keep it stupid, affectuous. A strong hug is worth a thousand words.

 

Indiana Jones and the Dial of Destiny : review

During my lonely time in the mountain, I have watched this movie in a small village. Unexpectedly, the room was quite full of people.

The movie is about the chase of the Antikythera, that is described in the movie as using the power of mathematics to make its possessor God.

 

The Antikythera.

Actually, Harrison Ford still plays the movie even though he is very old. Maybe we would have preferred new fresh people like the new realizator James MANGOLD.

The action scenes clearly have a lack of realism : many gunshots missed or delayed, the fact that the Antikythera falls in the lake but still remains in the hands of Indiana Jones, or the motorbike that goes quickly to the metro entry barrier and passes like a ghost. I welcomed those scenes with a smile of joke :-) .

Contrary to Indiana Jones 4 (that everyone hated because of the clumsy introduction), the action starts in a deep but smoother way.

In this Indiana Jones, the plot was really interesting, moving from a country to another and I don't tell you about the end, but I've found it amazing.

In short, I've liked this Indiana Jones, and I don't really care if the others don't.

Love is the solution to all problems

Today, we are both facing human and environmental problems.

Human problems can be a lack of contact, a lack of attachment, sexual misery as well as treason from a friend.
Environmental problems can be droughts, food shortage, pollution, as well as specism, the hatred against other living species.

All those problems have the same solution. The solution to all problems is love ! Deep love, the universal love known as αγάπη (agapi), that is the fundation of my philosophy.

Deep love means positivity towards people and the world, but also a part of humanity. For without empathy, love would be a fragile, short lasting thing.

It's OK to have sex before marriage, but consumerism unfortunately breaks families and hearts. I think that we should unite freely with the people we like, to eventually stay with those we love.

Make love, not war.

 

Xenophobia in modern Greece

In 1933, Adolf HITLER became the German leader. His party, the nazi party, had a hatred against Jewish.

Today, the hatred in Europe is against Muslims. And it looks like that xenophobia has moved eastern.

I have spent one year and a half in Greece, and I had NEVER found people that were so rejective against me.

Corentin – Γειά σου ! Πώς είναι το όνομα σου ; (Hello ! What's your name ?)
Greek – Όχι ! (No !)

75 % of the time I've found this stupid answer. I had learnt Greek, I had a work, but they didn't want to talk to me.

Even with Greek strangers, 75 % of Greeks have this xenophobia.

Why are they like this ? What's in their head ? What do they think ? Do they see strangers like monsters with long teeth or whatever ?

Greece has pushed away thousands of migrants, that are hosted by Turkey. Those migrants had their passport stolen, their boats destroyed, been beaten, imprisoned, forced to eat rubbish or to starve, and THE GREEK POPULATION AGREES WITH THAT XENOPHOBIA ! They always write "Φιλοξενία" or "Refugees welcome", BUT WHAT GREEKS DO IS RACISM AND STUPID XENOPHOBIA !

Greece has done EVERYTHING to make enemies. Greeks are masochist people, who prefer to die in their land instead of running away to a foreign country. They are 100 % into sacrifice, they know nothing about pleasure !

And you know what ? Greeks accused Germans of being "fucking nazis". Now 75 % of Greeks have become fucking nazis.

The militarization of Greece shows its unability to keep peace. A country is like an organism : the less policemen (or white cells) there are, the better it's protected from enemies. Greece has become a mentally sick country, dying and losing population in an auto-immune illness. The lack of travel for Greek people narrows their mind and makes it rot away like stagnant water.

Peace of mind is the condition to peace of land. So I will find an African woman and together, we shall move to Spain, a peaceful country. Even if we have to insist, even if we have to try again or another way, I prefer being in the arms of an open-minded African woman than being rejected and pushed away by nearly everyone in Greece.

What you give is what you get. Greece has chosen the path of xenophobia, like Germany did in 1933. We know how it ended in 1945. I just prefer to be far of this shit. I will never come back to Greece.

PS : If you are Greek and tired from the people there... Come to Spain, the plane is cheap in winter (50 € from Athens to Barcelona), and here, the people are more open-minded, and the food is much better :-) .

Discriminated people, unite !

In France, we have a maxim that says "The more crazies we are, we more we laugh.". This is kind of the Spanish mentality : Africans, Europeans, Asians, girls, boys, old, young... They are all together. In Spain you can see very different people sitting around a table and something to eat, living the conviviality.

In my opinion, the kindest people are often those who have harder lives, being discriminated just like I was. But as we are cooperative, we should just avoid stupid, conformist people and gather together as a rainbow of outcasts. The blacks, the prostitutes, the tramps... Why don't we unite together to be stronger ?

 

Retrospective about Nintendo

Among the video games social middle, we often agree that the PC is above the video game platforms, with games of better quality. However, it should be underlined that there used to be a nebulosa of creativity with the beginning of video games in the 1980s, with games through glasses, arcade games rotating 4π steradians wide... It used to much more prolific, there were no standards at that time.

Nintendo has won the war of mobile video game platforms in the 1990s by offering a much better autonomy. Being humble with a small shades of grey screen, powered by 4 LR6 batteries, made the Game Boy better than the other platforms, which had color and a larger screen, but poor autonomy. And Nintendo could carry on with the Game Boy Advance, which had color, large screen, trigger buttons, 15 hours autonomy and good games. In my opinion, the Game Boy Advance was the most balanced mobile video game platform.

A Game Boy Advance.

The war of video game platforms was terrible, with Sony betraying Nintendo, who was supposed to make the Nintendo Playstation until Sony disrupts and leaves Nintendo with a cartridge platform, the Nintendo 64. It was a hard time for Nintendo, and it is said that without a few games (Mario 64, Zelda Ocarina of Time, Pokémon Stadium and Goldeneye), the Nintendo 64 would have been a failure.

But Nintendo carried on. When they launched the Gamecube, they realized that all platforms had become powerful, and that they needed originality to make a difference. Nintendo understood that a race of performance would be like a war between dinosaurs : it would hurry up their end.

This is why Nintendo made the Wii in 2006. Small, convivial, energy saving, powerful enough and with a move detecting controller, the Wii had both the muscles and the brain. At this time, everyone was talking about it, everyone wanted it... Unconsciously, the people felt that Nintendo had won the platform w

Shigeru MIYAMOTO made us dream with Mario and Zelda, and we got attached to the characters of Nintendo, contrary to Sony who never succeeded in making something affectuous. Nintendo games may look childish, but they are based on pleasure, contrary to the darker Playstation games based on hard violence. We must thank Nintendo for making us dream.

Today, Nintendo produces the Nintendo Switch. After a lot of creativity and inevitable failures like the Wii U, Nintendo seems to have chosen a small originality, taking little risk.

In my opinion, the Wii was the best. Compatible with both controllers and games of Wii, Gamecube, Nintendo DS and Game Boy Advance, the Wii offered a gaming experience that was used to only 10 % in my opinion. Using the Game Boy Advance as a Wii controller offers a screen within the controller, the Nintendo DS offers a tactile screen. This WGNG (Wii Gamecube Nintendo DS Game Boy Advance) system has been considerably underestimated in my opinion.

As its launching name said, the Wii was a revolution. If it had kept its name, we could have said : "Hey, you wanna play the Revolution :-) ?". Even though the Wii was not the best sold Nintendo platform, it has conquered the heart of gamers, as well as non-gamers.

I wish Nintendo produces Wii again. Instead of taking a new risk, releasing new Wii games, but with better quality and better use of the possibility of all the possible controllers, would be a blessing for Nintendo fans.

I admire Nintendo because of their creativity. Attaching characters, games of quality, non-stop innovation... We can say now that Nintendo has won the video game platform war. They deserved it.

What is the future ? Analogic ? PC ? Producing new Wii ? Cartoons ?

In my opinion, the numeric support will crash on the long term. We know that in 2050, the rare earths used to produce numeric devices will be depleted... In practice, the semi-conductor industry has been lacking materials since 2021. And the newspaper said that recent video game platforms were unfindable because of this shortage.

If we have to connect to the Wood Wide Web and switch to analogic, we should conserve the best numeric video games. Whatever the technology, we are attached to our favorite video games, and if we have to come back to analogic, as everything seems to come back to its origins, I wish Nintendo makes the change and survives.

What is beauty ?

When you are in a beautiful city like Freiburg, everything is beautiful. When you are in an ugly city like Grenoble, everything is ugly. This is it : beauty is a mind, and makes everything beautiful.

First, I will make the difference between normal and universal beauty. Then, I will talk about the relationship between inside and outside beauty. In the end, I will tell you how is the sexuality of women according to their country.

I Beauty : normal or universal ?
II Inside and outside beauty
III Sexuality of women by country

I Beauty : normal or universal ?

Haute couture models are skinny. They often take cocain and force themselves to vomit to fit in their 42 size norm. But this is always the norm of a group ! Who would like to take a skeletic woman in bed ? You wouldn't know where to put your hands !

Mannequins are a normal beauty, but not universal.

On the contrary, if you take a balanced, smiling person, everything is fine. It is proved that most women get hot with shoulders, and that most men get hot with boobs. Women prefer athletic men, and men prefer (!) curvy women.

We agreed with a friend of mine that a C cup on a slim body is the perfect balance for a woman. We often agree that the hourglass shape is the most beautiful for a woman.
Women, on their side, prefer 16 cm long and 13 cm circumference penis, with circumference being the most important. They prefer men with the V figure.

But honestly, are numbers so important ? Dicks are like boobs : the important is not necessarily the size, but the way to use them ;-) .

If there is universal beauty, it is based on diversity ! There is not one most beautiful person in the world, there are several ones. Universal beauty corresponds to the universal taste.

The most beautiful woman in the world.

Even fatter, it's OK with the smile.

The concept of balance, of harmony, is very important in universal beauty. Bob Marley said : "The most beautiful curve of a woman is the smile on her face.". For the smile, a positive expression, makes harmony.

Soon, humanity will face an Ecological Crisis, discovering that money cannot be eaten... It's gonna be like in Greece : many slender women, and men liking their women with curves.

II Inside and outside beauty

Women lacking self-confidence are often complexed with their bodies, always wondering what the others think of it. They will destroy their body with surgery and heavy make-up, and they get difficult in bed. They get uglier when they get old.

On the contrary, people who are beautiful inside will remain natural. Making exercise in a sport room, getting strong and flexible, eating a base of starchy food with vegetables and little animal products, avoiding drugs like phone or alcohol, getting clean as often as your climate asks it, using egg yolk on the skin to make it younger... With simple care, you can get long-term beautiful.

I agree with ancient Greeks : inside and outside beauty are correlated. The ideal is to get a healthy mind in a healthy body.

Angry bracket :

(Damned, I HATE MY PSYCHIATRIST ! Because of this loser, I've taken 25 kg ! I hate his poison. I hate him. Death upon the cops and psys that rule this shit world :-@ .)

End of the angry bracket.

The Discobolus is the symbol of the masculine beauty, with a healthy mind in a healthy body.

III Sexuality of women by country

I will tell you about it from my own experience, how is the sexuality of women according to their country.

Spain : hot and flexible, based upon pleasure, not performance. Open to various fantasies.
Germany : quick and complicated. Urban, with links with LGBTQ and sexual union movements.
Russia : beautiful looks but passive and cold. Matriarcal, very bad against gays.
Africa : naturally curvy, as beautiful as Russians but very hot, dancing. Matriarcal, very bad against gays.
Greece : hard working, sacrificing themselves to give you an orgasm. Patriarcal, more tolerant with homosexuals.
Colombia : sensual, body perfectionists, slow and intense.

A word about French women. A friend of mine told me that they are cold in bed. He said : "Spanish women are hotter in sex, because they don't think it's evil.". I piss upon French women. I spit on their country. I hate them.

If you wanna find beautiful people in Europe, go to Freiburg in Germany or Ioannina in Greece. Make your own experience.

Feel free to leave a comment. I shall answer you, provided that you respect me.

Let's get a healthy mind in a healthy body, and take care.

Η μικρή μελαχρινή

 

Τα μάττια του έχουν το φως του βάθου
Το σώμα του έχει μια καταπληκτική αρμονία
Τα μάλλια του είναι μαύρα ως τα μετεορά διαμαντία
Το πνεύμα του εχεί τη ελπίδα του ουρανού

Αγάπη μου, πώς ονομαζέσαι ;
Έχω χάσει τη καρδιά μου στους δρόμους των Ιωάννινων
Μέσα το λαβύρινθο των εχθρότητων και των φόβων
Αλλά το πρώσοπο σου πάντα θύμαμαι

Έλα, σε περιμένω
Θα κάνουμε μια πανέμορφη οικογένια
Έλα, θα σ'ακουώ
Θα κατασκεύαζουμε μια πανέμορφη φάρμα

Σ'αγαπώ

Translation :

The small brunette

Her eyes have the light of the abyss
Her body has a perfect harmony
Her hair is black like the meteore diamonds
Her mind has the hope of the sky

My love, what's your name ?
I have lost my heart in the streets of Ioannina
In the labyrinth of fears and hostilities
But I always remember your face

Come, I'm waiting for you
We shall make a beautiful family
Come, I'll listen to you
We shall build a beautiful farm

I love you

Tribute to the travellers

The people who travel are totally different from the others. They are more open-minded.

Fascism is rising in Europe. Even Greece, a country historically known for its φιλοξενία (philoxenia), that is, hospitality, has become a nazi country towards strangers, offering much hostility instead of friendship, imprisonning strangers in concentration camps where they are starving and treated like shit. Why the hell would they be treated like this ? They are humans !

The thing is that Greeks don't travel. Proud of a beautiful, rich country, they get old without opening to the world and become nationalist, chauvinist arrogants, thinking the limits as restrained to Greece, forgetting that there is a WORLD outside ! It's difficult to travel out from our planet, but at least we should open our minds to get to know it at best.

Birth, death, going far... I think there's a relationship between that.

This article is a tribute to travellers. You widen horizons, discover wonderful things and take part of a universal culture, based on understanding, not xenophobia. Congratulations ! We need more people like you.

Why I don't like French

Why am I trying to flee France, this country that French consider as the best, with such arrogance that they forget that there is a WORLD outside ?

-Evil : French are incredible bastards. They don't love strangers, they don't love their friends, they don't love their girl or boy friend, they don't love their family, they don't even love themselves !

-Dictatorship : France has become a dictatorship, everything is forbidden ! French have a stilted, bureaucratic, legalist mentality, and this is why their technology sucks. They have invented the expensive, stilted Minitel, whereas US Americans invented the cheap and full of freedom Internet ! When you look at a hunting magazine, French don't talk about the ecology of the animals nor the hunting techniques, they only talk about the local rules ! In France, you don't have the right to sing, you don't have the right to dance, you don't have the right to drink nor smoke, and you cannot have sex because French women always run away and want to be alone, even prostitution is forbidden ! After the brain drain, the dick drain.

-Violence against the environment : French cut trees moved by cruelty, not even to build with the wood nor use it to heat in a chimney. The electrical mix sucks with only 15 % renewables and 50 years late in the run towards 100 % renewables. They mutilate their cats and dogs.

-No love : France has become an anti-love country, with an incredible increase in the break of relationship, an astonishingly incredible difficulty to fuck a French woman (scientific seduction manuals don't work with them), and the reward of what you, stupid jerks looking for romantic love in France deserve after spendind months on online dating to seduce a French woman : a cold one-night shot. And after she abandons you. This is it : they were cold from the very beginning : now you realize that they are cold in bed. French women will break your heart and burn the pieces on the altar of Chaos and destruction.

-Cowardness : this is very visible when you are in France : the people always run away. However, this is also true for English, who are the same as French, in worse.

-Stupidity : French spend all their time on their phone. They have no brain.

-Madness : French do many absurd things, just like giving money to the shit bureaucracy, a mad thing.

-Uglyness : French are becoming uglier and uglier, French women have no sex-appeal and French tend to get weak physically, they don't take care of their body.

In a word, I don't like French because they are evil, stupid, mad and ugly.

Where should I go ? Spain ? Greece ? Outside Europe ?
If I find love and garden, it's gonna be OK :-) .

Make love, not war.

Star of the sailor is back !

Xenophobia, repression, the coronavirus... After so much trouble, I have left Greece. I am tired of living in France and am now trying to move to Spain. Good food and good sex in perspective. Wherever I go, I've gotta find a field :-) .

As I move to a foreign country, I am pleased to introduce you, the international public, to the following of this blog about philosophy, arts and sciences.

Sex, tapas, and solar power ! :-)

Make children !

Translation from the French version of Star of the Sailor at https://etoiledumarin.wordpress.com/2017/04/28/faites-des-gosses/ .

When I hear French or Spanish telling me that they don't want children because "Bla bla bla, the crisis...", it makes me laugh out loud ! In Africa, the people are very poor, but they make children !

Children are positive, sincere, brave, full of energy... We need that freshness !

It's true that children are ignorant, but adults are all pirates and old are all zombies ! Well then, I accept my 6 years old mental age :-p .

It's better a void head than a head full of bullshit. It's up to you to fill it with your heart ;-) .

If you are an activist, instead of breaking your mind to have an argument with a fascist, make children ! They will be much more receptive :-D .

Don't do like in Idiocracy, where the intelligent couple waits eternally whereas the stupid jerks copulate like rabbits ! Find a kind person with who you will bind for a love for life, make children and give them the best education.

Behave like a responsible person ! Make children !

And if you are the super green of service, make 2 and give them the best !

I've published this article in the category Philosophy, on one side, because I am a strong defender of positivity and optimism, and on the other side, because it's much deeper than it looks !

I was 10 years old when the Pokemon went out. If you are part of this generation, just one click and welcome back.

What is the difference between old and ancient ?

It's a fact that the young have positive energy and the old have negative energy. However, old people are sometimes described as ancients, but I think there is a difference between that.

Look at the previous graph. On one side, the people who keep their positive energy up (I personnaly use energy drinks for that, but love is obviously the best) remain curious and accumulate experience. They are in a creative, ingenuous dynamics. On the other side, the people who lack positive energy tend to close themselves and lose experience. The first ones will become the ancients, the wises, whereas the second ones will become the old mad, the old.

I can't stand old people because they are mad, they don't listen to anything, they are fascist, racist, dirty, don't take care of their body, in other words, because they are evil.

I am interested in open-minded people, who are curious about all things of the world, the animals, the plants, the minerals, humans, societies, cultures, languages, music, painting... Those people are often more worth than the closed people, they are mentally healthier in my opinion.

If you want to become an ancient, you must remain curious all your life. As long as you keep your positive energy, you can become a wise person.

Coronavirus : we want freedom !

What's the meaning of keeping people closed in their house, with nothing interesting to do ?! We cannot meet people, we cannot kiss people, we cannot hug people... Who is the fucking bastard who invented the confinement ?!

We want freedom !

The coronavirus only threatens the weakest ! And Nature eliminates the weakest, making the population stronger. Who cares about seeing 13 % (my father says 1 or 2 %) of the oldest die, whereas it's time for them to do ? Whereas they are evil ?

Leave our youth free ! Let us make the revolution of love, to bring the human heat and the light we need now.

Sources of electrical energy : solar power

Solar electricity is clean and renewable. The Earth receives from the Sun more than 10,000 times the energy that humanity consumes. It makes solar electricity clean, renewable and abundant, not far from the ideal of an affordable, renewable and clean electricity.

I How solar electricity works
II Advantages and drawbacks of solar electricity

I How solar electricity works

Solar electricity comes from photovoltaic modules, that are mostly made with silicon.

Photovoltaic modules.

How do they produce electricity ?

They use the photovoltaic effect.

Photovoltaic effect = photoelectric effect + voltage

The photoelectric effect occurs in semi-conductors and transforms the photons, particles of light, into free electrons.

How then are the free electrons converted into electrical current ?

Silicon Si has the ability of being converted into a semiconductor with more or less electrons than Si. The lack of an electron is called a hole and allows movement of the electrical fluid.

PN junction figure. We can notice that at equilibrium, the free electrons of N (like negative, because the electron has a negative charge) and the holes from P (positive, because the hole has a positive charge), make a stable voltage, that will push the free electrons of Si into one way.

This is how a photovoltaic module works.

II Advantages and drawbacks of solar electricity

+ Renewable
+ Clean
+ Abundant
+ Cheap

Yes, I say cheap because today with global warming, we have a lot of sunny dry days, at least in Europe, and it's likely that solar electricity has become cheaper than coal or nuclear electricity.

Solar power is definetely the energy of the future, because hydraulic power is not enough for dense populations like today, but solar power is clean, renewable, abundant and available everywhere on the Earth. If CAES (Compressed Air Electrical Storage, a technology of electrical storage up to 85 % efficiency) is one day applied to tanks in houses, everyone will be able to store the excess of electrical energy of the summer to use it in the winter.

Sources of electricity : wind power

The wind is able to move things, like the branches of trees, fabric of boats, even more at high speeds. It comes from a difference of pressure in the air.

Let me introduce you to wind power. First, we will see how it works. Second, we will see the advantages and drawbacks of wind electricity.

I How a wind turbine works
II Advantages and drawbacks of wind electricity

I How a wind turbine works

The wind activates the wind turbine blades by a mechanism of forces.

The wind force F1 exerces a repell force F2, that produces another force F3 with F1 = F2 + F3. F3 makes the blade turn around the wheel.

The wheel turns and activates a gear box, that activate a generator, that makes electricity.

Sketch of the inside of a wind turbine.

Let's focus on the following formula :

p = 1/2 x ρ x S x v³ x C_p

In this formula,

• p is the power, in Watts, produced by the wind turbine ;
• ρ is the volumic mass of air ;
• S is the area of the wind turbine ;
• v is the speed of the wind turbine ;
• C_p is the coefficient of performance, a corrective parameter between 0 and 1.

We notice that the power produced by the wind turbine is proportional to v³. It means that the production of a wind turbine is highly sensitive to the speed of wind. If the wind goes 2 times faster, the production is 2 x 2 x 2, that is 8 times higher. If the wind goes 3 times faster, the production is 3 x 3 x 3, that is 27 times higher.

Classical Danish wind turbines.

Actually, the classical Danish wind turbines stop at high speeds. But it's possible, with flexible blades, to make wind turbines that work at high speeds.

In 1955, the CIAMO (Compagnie Industrielle des AéroMOteurs) made the FP5 and FP7 wind turbines, that work in cyclonic conditions. They were working from 3 m/s to 90 m/s. In my opinion, they made the most powerful wind turbines in the history of wind energy.

II Advantages and drawbacks of wind electricity

+ Renewable ;
+ Clean ;
- Produces enough only on mountain tops or sea coast ;
- Only works when there is wind.

I don't talk about the birds, 99 % of the time they avoid the blades, and only stupid birds die, it's not a problem to get rid of them.
I don't talk about the noise, it's likely the same as cars, which are largely accepted. I think it's possible to get used to it.

As a renewable source of energy, wind electricity is a solid alternative to depletable energies like fossil fuels or nuclear, which meet difficulties and high cost of damage in the long term. Fossil fuels burn the planet, which suffers from more droughts and a loss of food production, and the Fukushima catastrophe cost 210,000,000,000 $ of damage and ruined a country. On the contrary, renewable energies like wind electricity are long-term efficient, and are compatible with sustainable development :-) .

Sources of electrical energy : hydraulic power

The essence of water is love. This is why hydraulic power has so many advantages.

Historically, the first electrical powerplants were made with hydraulic. They are the base of the electrical network as they are able to store and release electrical energy.

First, I will explain you how works a hydraulic powerplant. Then, I will explain you the advantages and drawbacks of this source of energy.

I How a hydraulic powerplant works
II Advantages and drawbacks of hydraulic powerplants

I How a hydraulic powerplant works

The principle is to take a relief in the moutains, to build a wall a block the water so that rises a lake with a much higher pressure. If the relief doesn't exist, it's possible to make it by "mountainization", a new technology I have imagined which consists of digging a lake to make a mountain.

A hydraulic dam retaining water and making a lake, offering higher pressure at the bottom.

The pressure offered by the depth of the lake is a source of power for water turbines, because when a part of the water is released from the dam, the water flows faster and it gives higher kinetic energy.

Kinetic energy of a fluid equals

1/2 x ρ x v²

where ρ is the volumic mass of the fluid and v the speed of the fluid.

High speed water activates the turbines with a high power.

After, the turbine activates a generator, that makes electricity.

According to Bernoulli's law, the decrease of pressure in the fluid means a rise in speed. This is why dams offer a lot of electrical power, up to 10-20 GW for big dams like Itaipu or Three Gorges. Those powerplants, with their huge lake, are the most powerful electrical powerplants in the world.

It's possible, with the basin up and the basin down, to store electrical energy up to 85 % efficiency and at a large scale. The PSP (Pumping Storage Powerplants) consist of two basins, one up and one down. When electrical energy is in excess, we pump the water up to have more pressure. When electrical energy is missing, we let the water flow down to activate the turbines, that will activate a generator, that will make electricity.

Okinawa's PSP.

Luddington PSP, made with an artificial relief, moutainization.

What about fish migration ?

It's possible to make another river with a fish ladder, to allow the fish like salmon to move up and make their migration.

A fish ladder.

II Advantages and drawbacks of hydraulic powerplants

+ Cheapest electrical energy (even for water wheels)
+ Renewable source of electricity
+ Clean source of electricity
+ Abundant source of energy
+ Possibility to store and release electrical energy with PSP
+ Creates a lake
- Destroys the land

In the end, even though a part of the land is sacrificed, hydraulic power offers more advantages than drawbacks.

Sources of electrical energy : presentation

Hi everyone,

I wanted to make a series of articles about the advantages and drawbacks of all sources of electricity, and also explain you how it works. Today I have a master in solar power, so it's a subject I know quite well :-) .

The sources of electricity I will talk about will be :

• Hydraulic electricity
• Wind electricity
• Solar electricity
• Geothermal electricity
• Biomass electricity
• Fossil fuels electricity
• Nuclear electricity

I will not talk about magnetic energy and nuclear fusion, because those technologies don't work.

I wish you a nice reading.
