The E-Fuel MicroFueler, around since 2009, can convert sugar-rich liquids such as waste alcohol into what's called E-Fuel100 ethanol -- a fuel you can put directly into your car (assuming, of course, your engine is configured to run on biofuel) or use in generators to provide household electricity. The MicroFueler can't handle cellulosic waste material, such as compostable organic matter, but E-Fuel's new product, the MicroFusion Reactor, can. It breaks down organic matter into lignin powder and sugar water within a couple of minutes; the sugar water can then be used in the MicroFueler to create E-Fuel100 ethanol.

Unlike other ethanol production methods, the MicroFueler does not use combustion in the process, which purportedly makes it far safer. It is not, however, cheap: The device costs $9,995, with an additional cost of $1,995 for a fuel tank and a $9.95 monthly network subscription fee. Pricing for the MicroFusion Reactor has not yet been announced.
