I'm starting this topic to discuss renewable energy technologies, that
might be a little bit different from what we generally think of.

I'm going to mention two right here.

1. The new geothermal Power Tubes invented by Doyle Brewington. They
use a water free magnetic technology that can by burying a device that
it about 185 meters deep, 4 meters in diameter, and 10 meters above
ground in a plant that takes up only half an acre can be a 10MW power
plant, that will not require underground water, and will not deplete
heat, steam and pressure like conventional geothermal plants. Also
they can be used in a DRASTICALLY wider variety of sites.

2. Blue water. This technology runs river water through a membrane and
mixes it with sea water. The membrane can be used to generate
electricity by water molecules passing through (the opposite of
reverse osmosis). This could be done by diverting a portion of some
river than run into the seen (it would probably harm the fish less
than a conventional damm and could be turned off during salmon
season). Some engineers that the Netherlands alone could have 35,000
MW of capacity.

Any other concepts?
