  • t think that the usa & the west dont make this projects in the poor countries for political purposes ... i mean why they dont support things predicted to make the planet abetter place !!!

  • Quite interesting!

  • TheSolar2010

    Every home on the planet should use this if and when scaled down and can afford it...

  • I am skeptical because when we gather light we gather heat also and it translates few thousand degree heat more than enough to melt down silicon cells unless we have some cooling mechanism

  • In answer to the question about snow on the roof:

    There would have to be storage batteries for the electricity to be accessed in the dark, etc. anyway.

    I'm thinking the roof should be made of a material that would facilitate the melt of snow. It, along with rain would be stored in cisterns to supply water in the manner of Michael Reynolds' Earthship design. According to Michael Reynolds, most climates could supply enough light for power and water for domestic use.

  • The nanotube paint idea makes sense. This requires desert.

  • Sure one or those on your house would look brilliant. Why doesn't anyone make solar tiles or shingles and make roofs out of them? Seems to me it would be much more attractive and easy to do?

  • Well, would that mean we would have no electricity when it snows on our roofs?

  • If you focus all that energy on a space a few centimeters square, how does the Solar Cell withstand the temperatures? Also, how can you get kilowatts from such a small cell? Something very strange is happening and the Video did not tell how it works under those extreme conditions. But, thank-you anyway! Any alternative energy information is good to hear about! : )

  • There is a parabolic system that sounds similar to this in the works. It takes the extremely hot solar heated air to drive a microturbine. The solar company is HelioFocus and the microturbine maker they have a contract with is Capstone Turbine.

  • I think using the Sahara as electricity plant for Europe is not wise, cos it would mean long distant transportation of electricity. This makes the power grid less reliable.

    And solar energy doesn't require a lot of space, I read somewhere that if 20% of all the roofs are covered it is enough to supply the entire use of electricity..

    For my country (The Netherlands) windmills are more effective then solar based solutions.

  • Here is a way that a residential house could effectively store solar energy during the five hours of good sunshine, to last for the full twenty-four hours. Use a hydraulic elevator system lifting a very heavy weight, where the energy is stored by the gravity of the weight. When the sun goes down,or when more power is needed during the five hours of good sunshine, the very heavy weight movement is reversed and the hydraulics is used to generate power.

  • ^ Excellent idea!

    Only problem that could give is that the ground should be solid enough to carry the construction.

    One could also lift (part of the) the house itself.

    Buffering is the only problem to solve.

    One could also think of storing in thermo, chemical, pressure etc. etc.

  • I was thinking similarly also of lifting the backyard, with the actuators under the ground. Possibly giant metal springs could be used instead of gravity, to counter the hydraulic actuators movement.

  • Good idea, but do it with a fluid spring setup, similar to how a watch mainspring operates.

  • I have Solar Energy free guide ..

  • mmn yeah. but then again, Africa can sell the energy to Europe.

    Does anyone really live in the Sahara now? could that even work w/ wildlife? The wildabeat will trample the solar towers just like they did to Mufasa.

  • interesting..
