  • Can't wait to see those things crashing out of the sky.

  • this video looks like its 50 years old, where the fuck is my free energy already!?

  • It's intresting that energy always seems to be where we are not. :D

  • You are too much of a smart ass to take seriously.

  • Or, indeed, use a 'Kelvin water dropper' to create a potential difference, no dams required, just two buckets and some copper wire.

  • If you want to get more esoteric, build a giant glass house in bright sunshine. Cover the floor with a shallow pool of water, and make the surface black. Then collect condensation from the ceiling in a tank, and let it flow down pipes through a small turbine.

  • I think its useing most of its energy just to fly!

  • Coś zbyt skomplikowane....!

  • this could become political because of elect tricity.

  • Go to freemicrosoftpoint[DOT]com for a working one!

  • comment cela ce fait il que la manche a air est orientée differement de ce cerf volant autogire ?

    Ou est le fil de retenue ?

  • @sepulcrack Technologie qui ne fonctionnera jamais.

    trop fragile, se cassera facilement.

    Problèmes de stabilisation.

    la puissance développée fera utiliser au converti à la HT dans l'ordre les fils minces vers le bas.

    La ligne de longe plus lourde et plus lourde avec l'altitude.

    Le premier orage du vent et de la pluie puissants détruira.

    La première grève d'éclairage voyagera en bas de la longe le vaporisant.

    etc. etc. etc. ........

  • superbe résultat ! je n'ai obtenu de bons résultats qu ' en monorotor.

  • Hot rock technology why are we not using this?

  • A challenge: Build a machine that will use water and gravity to generate electricity. Sorry, no dams. Hoover dam uses @350 psi. ;in its turbines. Any ideas?

  • tidal power is created from the moons gravity attracting water on earth.

  • @jeremyclarkson3319  Naaaaah!! Reeeeally??!?!

    what an epiphany!!

    I thought the earth had indigestion from eating too much.

  • @lblmer Why no dams? That is very limiting. How about Dinorwig in north wales? Thats more of a lake with pipes and a mountain, but even then I think they used dams, and its a bit of a stretch to say 'generates electricity', stores might be a better verb. But any high natural water reservoir could concievably be exploited for electricity, with enough piping, just let it flow down building up pressure under gravity and expel it through turbines. Good enough?

  • ich glaube das nicht weil ich behaupte dass, es 2 elektromotoren sind die durch das kabel electrizität beziehen.

  • @Pucky0978 refer to what?

    re-make your statement.

    Doesn't make sense.

  • how so?

  • What about airplanes flying into the nearly invisible tether/power cable? It could really ruin some pilot's day, and part of the next one.... Stan~

  • To prevent aircraft colliding with the cables, just set up a no-fly zone in the area where the turbines are operating. There are currently tethered balloons at similar altitudes with no-fly zones around them.

  • this is making the SkyStream 3.7 look better all the time!

  • This is a test version, nothing more. The real thing would be *much* larger and stronger. The idea is that winds several thousand feet up are typically stronger and more constant, so flying this at those heights would make for more constant power. This is *not* for home use.

    The rotors are powered by the wind (like a gyro kite) and are connected to generators.

  • Is that like a Gyro Kite generator?

  • Will I have to have extra coverage on my house for when the wind stops blowing? Why would I want the generator to fly on a teather rather than just mount it on a pole where it is safe when the wind does not blow?

  • i'm not seeing how that generates energy

  • its simple! example, take an electric motor connect it to a small bulb with wire & turn the motor the bulb will light up bec of the electricity generated by the motor

  • great a copter for stick insects and victoria beckham

  • I like contra rotating helicopter better it was a working model not a computer simulation

  • dumb shit!! go to school and learn a bout gyro copters/autogyros

  • We need more people willing to experiment with new technologies, or adapt old technology like the gyroplane shown above.

  • but most of these contraptions shown are just gimics and prototypes with so many flaws. Like for example that gyroplane is like floating polystyrene. to expensive for what it does.

  • Yes but the Wright Brother's flyer was a prototype

  • good point!

  • so we don't really need oil....WOW.

    tell bush and his cronies.maybe they will crawl under his gold plated rock and die rich and happy

  • Everyone is wrong! The machine has two motors connected to an electricity supply. The fans spin at high speed, generating wind that blows the turbines on wind farms thousands of miles away. Okay, not really..BUT the generators are too small and once loaded, would stall. Battery charging only perhaps?

  • The catch o matic 4000

  • Who's going to catch them when the wind suddenly drops though? ;)

  • Back in the 1970's Stunt-Kites were all the craze, a dozen or so on two strings. Now we have all fabric flying wings. some can lift a grown man into the air! Why stick to rotary motion? Faraday also works in linear alternators. Mmmmm? Two sets of kites? one goes up, the other down?

  • it would use more power than created turning the friggen props to keep it in the air, well at least the government will have another excuse for u.f.o deniability sightings lol

  • LOL huh lol huh doh the props don't keep it airborne the wind does, the Rotors are turned by wind passing over them

  • Soon we will all be living on floating islands. <.<

  • Who was the scientist who flew a kit in a storm to see what effect lightning would have running down a wire: Benjamin Franklin? This might have a similar danger in Lightning. but its a good idea if it could slide up and down two masts. So when no wind, people could not complain about the visual impact(apart from 2 masts).

  • Who is going to complain? Free energy in voltage of millions!

  • never in a million years. I would love to say more but the clip says it all. Please stop wasting your time on flights of fancy and concentrate on a viable method of nuclear waste disposal

  • Creepy... could this end up being yet another source of power just like solar power which ends up pretty much useless?

  • Solar power is the second fastest growing energy resource on the planet, after wind.

  • and ..

  • I was replying to 12ob8logland who said 'could this end up being yet another source of power just like solar power which ends up pretty much useless?'

  • Hmm.. Maybe because the wind is better at higher altitudes, and the power is transferred through a cable?

  • Maybe, but wind doesn't stay constant and a single cable would allow the generator to move around quite a bit depending on how much slack it had. Also, I would think that multiple generators would be used in close proximity, what would stop them from hitting each other or tangling their cables?

  • Yeah, good points.

  • I don't get it. Why? How would you transfer the power? Wouldn't a strong wind send it crashing?

  • so we can move the wind farm from the ground up to the clouds??

    angels better be careful or else their wings could get caught...

  • hahaha

  • wot the hell!!!!!!!!!!!!

  • Looking good when the grounds flood you got the answer already ..forward thinking or what
