Stevo, latest figures out today on EV sales via Bloomberg show sales have now hit 4 million electric cars; a 77% increase on 2017 - and still one quarter to go for 2018. Its not the number of EVs being a big deal, its the staggering rate of growth. And its nothing to do with being a greenie - its cold, hard facts and money in my pocket. The insinuation that just because I'm a retired naturalist that I'm promoting EV/batteries is a side issue. Although, the environmental benefits to this tech is an added bonus - no doubt about it. You'd have to do circa 7,000 hours research on this subject (EVs/lithium batteries) before you could equal my knowledge. Come back when you've done that and admit you were wrong. Lets see if you're man enough.
