Geez Acey, you're making me work :) 1. Ofcourse Fossil fuel is the easiest and cheapest source of energy in today's economy. Nowhere is it being costed in for the damage it is doing to our environment and green house ramifications. Big business won't change until it runs out or our...

Richard I'll try to get more info. I suspect Acey and others are much more knowledgable on this subject. I don't know about Sorgham but Brazil uses sugar cane and they do use the Bagasse to power their ethanol production and they have surplus energy that they feed onto the grid. Don't...

I've seen articles indicating it cost more energy to produce Bio-fuels than it produces. But I have a problem with this. If this is the case then why does Brazil produce so much ethanol for fuel, surely they'd run out of petroleum (or cost them heaps in foreign exchange). Also I beleive...
