Robert O'Brien, Professor of Chemistry at the University of Victoria in BC, explains a simple means of taking the last drop of energy out of today's hybrid vehicle's batteries.
About twenty years ago, when battery driven toys and hand tools began to be common, an American engineer did a calculation based on the then cost of electricity from the mains and the cost of the same energy from the standard D cell used in flashlights (torches). He concluded that the cost of energy from dry cells of the day was over 500 times the . . .
