Doubts about EVs
McCabe-Thiele (Ted):
Yes I've watched that before possibly from a previous link here.
About 65 odd years ago when most of us had coal fires and trains were steam driven I remember the smog. Acid rain was named the cause of all sorts of environmental disasters. Then it was CFC's burning a hole in the ozone layer - now it's Diesel & Petrol cars.
In 25 years time when we have moved to heat pumps I suspect it will be the leaking refrigerants to blame. How much natural atmospheric pollution do volcanoes produce I wonder, not to mention all the munitions being exploded in various countries around the world.
The funniest bit is when they blame Cow farts for the excess methane gas - us humans seem reluctant to accept that sometimes the answer is outside our current level of understanding.
I blame Beelzebub if that helps.

I'm afraid that the sale of Avgas to anything other than aircraft was banned a good few years ago - at one time there were quite a few race bikes running on fuel supplied by the local airfield. Now however, it has all ended - I believe because the rate of fuel duty is/was different.
In addition, Avgas still contains lead, so not much good for anything with a catalytic convertor fitted.
In general, piston - engine aircraft do not use motor fuel due to risks of vapour lock through ethanol, I understand. In some cases it was deemed possible to use motor fuel, however it involved restrictions on altitude (maximum of 5,000' from memory), measuring fuel temperature before flight and more.

Mogas, as they call it is used in a lot of microlight and ultralight aircraft if approved for their engines.
flatfour:
Mogas has normally been approved for aircraft types below Groups A or B. I understand it is due to the lower expected operating altitudes and reduced climb performance.
Having never operated anything other Group A or B (single and multi - engine landplanes) I don't know whether the additional restrictions that affect Group A are applicable to other categories, or not.
In all likelihood, it also takes account of the fact that runway requirements for ultralights and microlights are minimal, therefore as with a glider there are numerous safe landing areas that larger, heavier aircraft could not use without serious damage and/or injury to occupants.

The world's population has more than doubled just in my lifetime and they all want transport, feeding, and an ever better standard of living. Genocide anyone.

Precious little to do with global warming.... we are in the last third of a receding ice age, of course we'll get cosier!
