E-fuel 100 Microfueler developed by Floyd Butterfield and Thomas Quinn, offers the flexibility to generate biofuel (Ethanol @ $1/gallon) at your backyard. This system is compact like a washing machine and operates on sugar content and yeast. Read more on NYT coverage

Perhaps, innovative part of the system is an advance membrane distiller, which separates water from ethanol at lower heat and fewer steps than other ethanol systems

Critics flaunted the claims and said that sugar costs 20-cents per pound, and system requires 10 to 14 pounds to make a gallon of ethanol, hence it is not viable to produce ethanol But Butterfield and his Silicon Valley finance whiz/business partner Thomas J. Quinn swears you can buy “inedible sugar” from South of the Border for 2 to 3 cents per pound.
