re "Any plant based fuel grown in soil is subject to all kinds of vagaries - blight, drought, locust plagues" Brazil does quite well with cane ethanol , very successful at it, for running cars there. Big National Geographic story on it a few years ago. The processing plants even generate their own electricity from the fuel they produce. not saying it's perfect or a panacea ...just that at least that one country has done a lot in the direction of not using fossil fuels for cars. I believe they are a net exporter of petroleum even.
