In his review of Lester Brown’s Plan B 3.0: Mobilizing to save civilization, Fred Pearce writes “we already have most of the technologies needed to fix climate change. Some require a firm kick-start, such as hydrogen fuel cells for cars.” (26 April, p 48). George Monbiot, in his book Heat, thoroughly explored that option and declared it unworkable. On the other hand, cars powered by solar-charged batteries are eminently feasible.
