in about 3 - 5 years there will be the perfect infrastructure for hydrogen-filling stations (first in Europe and Asia/Japan, later California) and many models from different producers (Toyota, Daimler, Huyndai, Honda etc.); so the wind-of-opportunity for Tesla is only 2 years...this is a great short, Tesla...hyped by investment-banks...(comparision hydrogen vs battery = 3 minutes loading/filliing, 400 miles-plus, about US $ 10/100 km...secure...and cars costing the same as diesel-hybrid...and not so expensive as Tesla.....see. Ballard...BLDP, US $ 1,39
I agree. I always get vague or no answers to most every question when I ask the Daimler/Mercedes guys questions. And this is from their reps manning their fuel cell exhibits. Probably better used, if at all, for semi's, buses and trains.
