    In the future, will solar energy be the main source of our power?

    I realize that current solar panels are not that efficient. However, is it possible that they will eventually (in 20-30 years) be efficient enough to provide most of America’s energy needs (75% or more)? The reason why I ask is that I once saw an TV interview in which some researcher from MIT was questioned about solar panels. He basically said that solar panel efficiency will double every two years.

    Is this true? If possible, could you please cite an article or a reliable source?

    I know a lot of companies and people are starting to use solar power, and I think it’s a really good idea. Do you think we will ever stop using as much oil, and convert mainly to solar power in the future?

    Solar power experiment?

    Hey folks, first question from me here.

    I was wanting to run a little experiment this summer involving car batteries, 100 watt solar panels, and my computer, but I lack a certain amount of technical knowledge. I was wondering, is it possible to hook up a computer to car batteries that can be recharged using solar panels?

    My computer and monitor draw about 163 watts per hour. What I was intending to do was have two batteries hooked up to supply power to the computer, with two more batteries being charged via solar panels during the day. The objective was to run my computer without having it plugged into an outlet.

    Is this even remotely possible to do? What kind of batteries should I use?

    Thanks.
