Where do you think all of the grease (soybean oil) from McDonalds and Burger King end up? Not the stuff in the dumpster out back, that is yellow grease and is fed to cattle.

The stuff you eat. It ends up at the county sewer plant, floats up to the surface in one of those roundy,roundy separator tanks. It is then skimmed off (or Lake Erie, your hometown river, etc would fill up with them.(They float). This stuff is hauled off by the truckload to be spread on fields to decompose.

It could be heated, filtered and burned in a diesel engine/microturbine. Pretty much if you have a use for heat, you can use the yellow grease for power and heat. Use more than one leg of the Rankine cycle and efficiency increases.

Use batteries for storage? No way. Push it right back thru the meter to the grid. The power companies have changed their attitude about this a lot. The beauty of this method is that you can buy a really small diesel and just let it run.

The problem with environmentalists is that they don’t like icky sources of fuel.

Scrap tires can be chunked and burned in a regular coal furnace (TDF- Tire Derived Fuel) provided it is an old style chain grate stoker. These could easily be used as a sweetener for coal generation plants. Tires burn cleaner than coal (at furnace temps, don’t try this at home!)with lower sulfur content than bituminous.

NIMBY! Your not burning stinky tires here! Tires don’t smell bad when burned at hight temps. It is incomplete combustion that causes that acrid smell.

No, what we want is inefficient solar panels that use more energy to create than produce. Waste in someone else’s back yard, to boot. And a battery system, cause I want to live in my 4000 sqft log cabin off the grid.
