Yeah, Big Gav's a mate... another Sydney peak oiler.
I don't think that article answers the questions about how much fuel this could provide to the farming community though, and how dispersed the Biochar factories would have to be to make it fuel economical. How much biomass can those big-rigs carry to the factory, how far, using how much fuel, and then carry all the biochar and fuel back?
How are we going to do farming if oil imports are cut by 50% over the next 10 years? (rationing)
How are we going to continue mining, farming, freight and construction of the next generation of renewable energy systems (including Biochar power-plants) if many nations hit as low as 1/5 their fuel in the same amount of time? (Australia peaked in 2000 and our oil production has plummeted! If we can't import... we're stuffed. Instant
Greater Depression, just add water. Well,
remove oil.
