more on alt energy:

Really? No one thought of this before? I wish I had!

It's PERFECT!

Lenses to concentrate sunlight on solar cells so that the solar cells get more light, thus converting more of that light to electricity. Smaller photovoltaic cells are making more power due to these lenses.

My thoughts on replacing fossil fuels is that we won't find only one replacement. It's going to be a bunch of small replacements that equal up to a total replacement. Vegetable oil, ethanol, solar, wind, hydroelectricity (not just damns, but tides and waterfalls maybe?) and maybe even more, will all add up to equal less energy than we use now, but hopefully with things like advances in engines, lighting, heating, and cooling we'll be able to reduce our needs.


...some shifts in attitude would help too...


however, one final thought on this (for now) is that it won't happen until gas prices skyrocket (beyond 5$/gallon, closer to 10$...maybe more) and stay there for a number of years.
