I'm sure you're a world leading electrical engineer. Your answer bears no resemblance to the point I made which , to clarify, was about achieving what is seemingly impossible. You seem to work within a company/ industry defined construct. It is rare any engineers that work like this come up with industry changing technologies. They are more often than not due to outside influences and sometimes people not connected with that particular industry at all, especially as that industry may not exist at that point (Edison, Turing, Gates, Watt. Etc. Etc). It is often those that say it can't be done that suffer the most ridicule in them books of history.
Your simplistic nonsense that engineers only do things when ambition and risk are taken into account and only when globally scaled (?) is just that.
It is fantastical ideas that drive good businesses forward and constant reinvention is good for everybody, and to bring this back to the the tread, particularly the climate. Especially if we can get/ harness alternative power sources.
If we had 100% renewables across the globe and put no new CO2 into the atmosphere wouldn't this be good for both sides of the argument?
