cylonlover writes: While we’ve seen the development of solar cell technologies that employ nanoscale 3D structures to trap light and increase the amount of solar energy absorbed, MIT researchers have now used 3D on the macro scale to achieve power output that is up to 20 times greater than traditional fixed flat solar panels with the same base area. The approach developed by the researchers involves extending the solar cells upwards in a three-dimensional tower or cube configuration to enable them to better capture the sun's rays when it is lower on the horizon.

I've never been canoeing before, but I imagine there must be just a few
simple heuristics you have to remember...
Yes, don't fall out, and don't hit rocks.
