The Massachusetts Institute of Technology is on the cutting edge of alternative energy technology,

“MIT scientists have developed a self-assembling photovoltaic cell in a petri dish. Phospholipids (think cell membranes) form disks which act as the structural support for light responsive molecules. Carbon nanotubes help to align the disks and conduct electricity generated by the system with 40% efficiency. The assembly process is reversible using surfactants to break up the phospholipids. When filters are used to remove the surfactants the system reassembles with no loss of efficiency even over multiple assembly/disassembly cycles. The results were published September 5th in Nature Chemistry.” [MIT]

Now if only someone could manufacturer some solar cell that are affordable.

Its amazing how far logging has come since the days of the lumberjacks and chainsaws.
