It’s only fossil fuels that are against the SOTA rules, not combustion. So a candle powered radio would be OK provided the wax was plant or animal based and not from paraffin.
Over their lifetime electric cars are definitely more environmentally friendly than petrol or diesel cars. This is even more so as the electricity supply becomes more renewable.
The little Mamod steam engine has an alcohol burner, so if I ferment the alcohol and distil it I should be within the rules ?

Within SOTA rules but probably not HMRC rules!
Most notably in my car! It preheats the battery before I do a rapid charge.
How thick are they?
I’m looking for some but want to be able to fit them inside my gloves which are already a tight fit.
Do they got too hot to be against bare skin?
I’ve used the Hot Hands pouches and they are nice and small but take a while to get going and are still hot well after getting back to the car and home so a lot of the heat seems to be ‘wasted’ heating my car/house.
Me burning batteries to produce steam to produce electricity isn’t necessarily burning fossil fuels. Last year, China produced 44% of its energy from renewables.
Given the USA produced just 22% of its energy from renewables in the same year, there’s a stronger case for disqualifying me from using my KX-2 on a summit that burning a Chinese battery to produce steam to produce electricity to warm Martin’s gloves or his radio or what ever this thread was originally about.
Thank you.
N.B. Scotland produced 113% of its energy from renewables in 2024.
Peter they are 18mm thick. There are three heat setting. The coolest is comfortable. I haven’t needed to go above that.
Hope that helps.
But 80% of that is used for Midge Hoovers

once you get past around 60-80k miles they are.
