He told me that the environment doesn't care about per capita, so China is the biggest problem. I asked him would their emissions therefore become irrelevant then if the country was chopped into 10 parts, each now 'only' having 1/10th of the emissions of China. THIS is a good example of why even th...

Urban busses are a GOOD match for EV. Frequent start/stops (regenerative braking) and duty cycle (significant fraction of time at stops. Not that "Diesel pollution" is why se saw the brief experiment with "Stirling" busses come to a halt. Stirlings would seem to be clean burning ...

Not a bad guess, only off by about 50 miles/

It goes back decades, if not centuries, last century it was called a haybox! The first reference to "cholent" is 12th Century << Religious Jews cannot cook on the sabbath. So how to have a hot meal Saturday breakfast, lunch and evening. ---- especially in summer in northern latitudes woul...

I think that because how this works in different places is so different, statemnts like this misleading. Not only the methods being different but the time intervals. HERE (US) the primary price the grid pays the suppliers is fo six month contracts (and there can be longer). The bidding W. works like...

Sorry if I came on strong. And I don't know how it works UK or Eire getting "building permission". Or what happens if you exceed that permission. But because I sit on our town "energy committee" and so was at the presentation before the "building permission committee" (...

Both this waste of energy and the waste of energy that is crypto currency are unsustainable. However these are two different problems in the sense that the waste with crypto is intrinsic. The cost of power to "mine" is what is ultimately the determining factor. The waste with AI is because...

That's a shame, I hope those particular WT's are unusually loud, and that newer ones are better, especially seeing Dan's link to new tricks for old dogs. Unless your courts terribly different than ours in a case like this, I believe the absolute level of the noise not relevant IF IN THEIR PERMIT TH...

A lot of the EVs have body shapes designed for low air resistance. Makes a HUGE difference on the question of whether rolling resistance important. And for THAT, the biggest factor is tire pressure. I used to be very conscious of that late 60's/early 70's driving a Saab. Since Saab an aircraft compa...

is that why so many cars are so noisy nowadays? And how is dire rolling resistance compatible with energy efficiency? (Maybe the noise from some is the physical manifestation of the energy wasted...) Rolling resistance becomes trivial compared to air resistance once at normal speed for a normal car...
