Solar Energy to 7 Billion People

By exploiting the powers of nanotechnology and taking advantage of nontoxic, Earth-abundant materials, Berkeley Lab’s Cyrus Wadia has fabricated new solar cell devices that have the potential to be several orders of magnitude less expensive than conventional solar cells. And, by mastering the chemistry of these materials—and the economics of solar energy—he envisions bringing electricity to the 1.2 billion people now living without it.

  1. Wonderful job!!!

    It obvious that, as of today, nuclear energy is more poweful in terms of capacity than solar energy. Then after extracting your nuclear energy, where will we pack the waste which is known to be so harmful?

    Solar energy is the best energy in terms of substainability.

    I fully agree with the views of this scientific team and encourage them to keep doing the good job. Only by working on this, will we succeed to increase the capacity, reduce the cost and widespread its use.

  2. I agree 100% about him not knowing what he is talking about. He is approaching this topic from a humanitarian view only

  3. This guy either doesn’t know what he’s talking about, and/or he’s a shill for the genocidalist/environmentalist movement. What matters is not nameplate capacity, but the actual power generated. A watt of nuclear generating capacity has an availability factor of 95% and lasts for 60+ years, whereas a watt of solar capacity only has an availability factor of 25% and a life of only 20-30 years. In other words, a watt of nuclear will generate 6-12 times more power than a watt of wind or solar.
