Solar Energy Potential For Water Depollution

With the huge progress in solar energy capture there should be a potential for its use in cleaning the environment. Water being essential to life would be a good place to start. I think solar energy could be of use where the location is out of reach from the grid and the otherwise burning of fuel is contra productive. Going from time limited measures to more continuous cleaning would reduce the time and be more effective.

Communities around Open Source Textbooks

I think the next step after the introduction of Internet ready Solar Tablets for developing countries like India and others in Africa is to establish learning communities around Open Source Textbooks. Free books with an open license that makes it possible to keep the book up to date. If successfully implemented these communities could improve the learning experience for the student. Being able download an Open Source Textbook and ask questions on the content of the book, read alternative explanations, view video and cooperate with others on-line would go far.


I think this is where the innovation needs to be, not making the textbook look like something that fell out of a Hollywood movie.
