An anonymous reader writes "All Power Labs in Berkeley, California has produced and sold over 500 machines that take in dense biomass and put out energy. What makes the machines special is that instead of releasing carbon back into the atmosphere, it's concentrated into a lump charcoal that makes excellent fertilizer. The energy is produced cheaply, too; many of the machines went to poor nations who normally pay much more per kilowatt. '[T]he PowerPallets are still relatively simple, at least as far as their users are concerned. For one, thing Price explained, much of the machine is made with plumbing fixtures that are the same everywhere in the world. That means they're easy to repair. At the same time, while researchers at the 50 or so institutions that have bought the machines are excited by opening up the computer control system and poking around inside, a guy running a corn mill in Uganda with a PowerPallet "will never need to open that door and never will," Price said.'"
