Burst of Energy Forward-thinking entrepreneurs are making leaps and bounds in the field of renewable clean energy. How can you get involved?

Walk through the maze of metal kegs, six-packs of boutique beer,and cartons of pop, juice and fruity syrup on Tim Curtiss'production floor, and you'll think for a minute that you'rein a beverage warehouse. However, these are just raw materials forLiquid Resources of Ohio LLC in Medina, Ohio. Beverage companiespay Curtiss, 45, to take out-of-date or flawed products off theirhands. Curtiss' company then smashes the containers and,through fermentation and distillation, converts the liquid contentsinto fuel-grade ethanol.

Launched in 2003, Liquid Resources has the capacity to produceabout 3 million gallons of ethanol a year. As both gas prices andfears of global warming rise, ethanol looks better and better-itburns far cleaner than gasoline and reduces our reliance on oilimports. Most cars already use fuel that contains up to 10 percentethanol-usually produced from corn -- but Curtiss says some expertsthink cars could run on a mix of up to 40 percent ethanol. Manycity buses run on fuel that's 85 percent ethanol.

And not only does Curtiss' company produce clean fuel, butit also helps fight the burgeoning piles of waste that threaten tooverwhelm our landfills. The company uses every bit of its rawmaterials: Metal, plastic and cardboard containers are crushed andshipped to recyclers; glass is sold to abrasives and road-buildingcompanies. The company's only waste product is water.
