This is part of my homework and i cant find it anywhere. Please help. Sources would be useful

When they are supposedly in support of any measures that lead to reduced CO2 emissions?
(The reason why I ask is because in Germany it is untaxed and they are trying to get as many people as possible to use it, wheras here you are actually penalized by using straight veg oil, you pay more than the tax on biodiesel…)

I CAN’T use a car or generator, is there another way?
Safely and so that I can record how long it was burning

Corn, sugar cane, have been used in producing ethanol which can be used in mixes— surely other sources and processes are being studied.

to heat 50 gallons of wvo in a 55 gallon steel drum- would a 115 volt immersible element heater from a hot water tank do the job? the oil has to be heated to 130 degrees f. I wonder how long that would take with that setup?

Is it possible to convert a toyota camry so that the engine will run on biodiesel? Yes, no, maybe? If so, how complicated will it be? Approximately how much time and money will it cost to make this conversion?
Will it even be worthwhile to do this?
