WiPower uses induction (magnetic coupling) to transfer power from the base station to the receiving devices. They are claiming 68% efficiency in the transfer of power and believe that they can achieve 80% efficiency. A regular power cord is 58% efficient.

Hi,
Well done. I’m working on a short film about sustainable alternatives. See http://www.youtube.com/candeepics for a sample. Its called “A Bright Alternative”. I’m looking for a shot I can clear to use that shows coal mining removing a mountain. Can you tell me who’s photo you used and where I might reach them for permission to use? Thanks,

As I noted in the article, it will take time to stop producing new coal plants. I think about 10 years at a minimum for the USA. Longer for places like China and India. Getting it done that quickly will mean a crash program to accelerate every other energy option. Nuclear, biofuels, natural gas, wind, conservation, efficiency. For nuclear to start making a big impact in the USA, we will have to remove the bureaucracy which drags out plant construction. It can take 5 years to make a new plant, but the bureaucracy drags it out to 10-15 years. We also would up-power all of the current plants. The waste will not be a problem if we create thorium flouride closed cycle reactors to process the long term (10,000 year) waste.
GE and Hitachi are talking about making 100 nuclear plants worldwide over the next 20 years. That is just their share. The French and other companies would make that number or more.
Thanks for this. I am doing research on coal with the idea of proposing a moratorium on new coal fired plants. Any further thoughts you have in this area would be appreciated.
