Why Electric Motors Are 3X - 4X More Efficient Than Internal Combustion

Bad experiences with the old ones AIUI.

Same in the UK but that's because for some strange reason we don't have enough diesel refining here and have to import lots of it.

I see you're unwilling to respond to a factual statement instead of an emotional one.

Let me ask you directly.

Does or does not Los Angeles suffer from a regular thermal inversion layer that traps in pollution ? Therefore making it's use as any reference quite worthless.

Graham

Not even remotely. It's CRITICAL !

That's

You have neatly shown that correlation is not causation.

Not all diesels are like that.

You can buy diesel Jaguars, Saabs (my goodness both of those broke a few hearts) and BMWs here too along with Mercedes who have offered diesel for yonks.

And then there's all the small diesel cars too with phenomenal economy.

Graham

Scandinavian countries can do it.

Yes, there is an inversion layer that forms fairly often at a few thousand feet, locking in the haze from the ocean along with everything else.

It's far, far better than it was in the 1960's, though, because the photochemical O3 component has been reduced by auto NOx and HC emission controls. I've lived in and around LA since the 50's, and can vouch personally for the improvements. The air is clean enough now that I think we're past the point of diminishing returns.

IIRC, the original Indian name translates as "Valley of the Smokes", from the low hanging clouds over the campfires.

That's my understanding too courtesy of a 1969/1970 edition of Paul and Anne Ehrlich's "Population Resources and Environment". Given to me as a Christmas present by the then Science Editor of the Guardian newspaper (UK), Anthony Tucker and signed by him.

We not only can, we actually do it. Many households here in Sweden are heated with waste heat from power plants. Thus the heat is not really wasted.

There's always a tendency to think about heating and forget about cooling. The US population has shifted towards the South, and there is that pesky warming trend we hear about...

The point is, without AC it would be difficult to live in lots of places, so waste heat would have to be converted to cooling to get the same effect. Can be done, but requires big changes. For places like Texas, solar panels that generate the most when the sun is beating down on your roof seem like a better bet---plus they would shade the roof.

It's brilliantly simple. And more should be done along these lines. Yet why do the 'greens' just want more taxes, wind turbines and hopelessly inefficiencent and expensive solar farms ? Because they just want to change our lifestyle, not make it more efficient.

You mean cooling at the moment actually.

Only 15% of the incident sunlight is converted to electricity. It won't cool you much. What you need is better insulated and built housing, offices etc.

A/C is NOT the outstanding problem for most of the world.

Graham

Pity about the cost of enough panels to run the AC.

And beverages taste better :-) A "pollutant" with many uses, also in the food chain ...
