"But with new direct injection, pressure charging and other technologies, two-strokes are now more efficient than four-strokes." My University project (about 30 years ago) was to direct inject a two-stoke. It was something like as TS125 that we had on a dyno. Nothings new and I thought that I was ground-breaking!!!!
I recently purchased a pushbike and I found going down hills is much easier. I doubt I am capable of generating anything let alone Watts
This country has a fine recent tradition of overly ambitious pie in the sky ideas which the politicians who suggest them do not have the means to carry out. See also Brexit generally and also Boris’ bridge and Failing Grayling’s ferry company in particular
I was talking about this with one of my electricians yesterday. We were under the impression that our infrastructure is inadequate now and certainly wouldn't support electric only without massive investment.
Infrastructure isn't there, the cabling itself isn't sufficient, extra demand etc. You will be paying for this via your bills. Then again, the less you use the less you pay. It's definitely coming regardless. I'm not sure we have the amount of skilled labour to carry out all the works needed.
