It’s with human intervention that coal seam fires have really caught on, so to speak, in the past century. Mining exposes coal to oxygen, and coal, as we know, burns very, very easily. With plenty of fuel and oxygen, a small spark can ignite a blaze that grows to cover miles and miles.

About how much does the new electric Hummer pickup weigh?
A. 10,000 lbs
“I could care less whether you are impressed.”
LOL! The phrase is:
I couldn’t care less whether you are impressed.
“and there are always a couple of Freepers peddling the lemons and pretending it is lemonade.”
Lemonade is made from lemons.
Sounds like a piss poor alternative to me.
Urine trouble for saying that.
You're right.

Uber, taxi drivers. Often times more than 8 hours a day.
Fuel cells are problematic in both cold weather and hot weather. A by-product of operating fuel cells is production of water, which can freeze and clog or destroy components. If the operating temperature is high, the water can evaporate and destroy the membrane separating anode and cathode, causing failure. Fuel cells are more problematic than EV batteries. Gasoline is a far better alternative than fuel cell use in extreme weather.

Uber battery swap station
I think the big problem with battery swaps is verifying the quality of both the one being off-loaded and the one on-loaded. Imagine being given a $20k pooped out battery and fighting them to take it back.

Software gives you the condition of the battery. You won’t get a pooped out battery.
Well, I guess I am wrong. The fuel cells that I have read about was on a submarine where the temperature is tightly controlled.
“Also, I know an EV battery has only about 25% of normal range in cold weather.”
A more recent study conducted in Norway, however, showed that the average cold weather range loss for 20 popular EVs was only about 18.5%. This figure is far closer to the EPA-estimated 15% efficiency loss of gas-powered cars.

You run out of gas?
