It amounts to 20 sq meters and as long as it is sunny can per the article run operate the bus. At other times it will need charging. This to me suggests buses completely covered in solar panels because it would at least amount to a profit margin's worth of savings over the life of operation. It would not be hard to hit to hit 13% with that I am guessing. Funny that 13% number because that is the supposed economic efficiency ceiling on petrol fuel energy. Coincidence suggests it might be a bit optimistic even in its context where you put a dollars worth of economic input in and you don't even get 13 cents back with petrol wheres with green energy its as if it were over unity way over unity, no subsidies needed going forward and never much needed even to accelerate its start. It wasn't long ago that someone hyper miled a bus 1100 miles on a single charge. It is really a happy moment, Germany is just about set to completely phase out coal, and the T admin is going to try to force the grid to buy dying coal- claiming its necessary for national security- what a bunch of BS, but ok no need to keep it running just don't dismantle it and let some coal sit in a yard, but its having to hide this action behind supposedly having to do the same for nuclear. A diesel ban is about to hit Europe, phase out in Germany in 3 years. Thinking again of all the big names that are going full electric autonomy (autonomy won't work with the fool cell long tail pipe scam) to include Apple with Volkswagon, Toyota with Amazon, Google with Honda, Tesla with Panasonic, with Boeing and Airbus getting in on air autonomy at the least (they've been at it for a while- but will be in direct competition with ground autonomy) IBM, Cisco, Oracle, Intel, Nvidia, AMD, Ali Baba, Baidu, BYD and all the other Chinese and Indian firms. China now has a fully electric battery driven freight train. I know mag levs are obviously electric but need green power energizing the.
