Does that stay in the car or outside the car? Won't kill the passengers?

It appears to have a ducted exhaust that he has run to under the car,

But given his worries about killing himself either by CO poisoning, or other form of gas poisoning, I would have thought a 12V heater ( there are plenty of them around) running off a separate 12V car battery would have been a better option than running a small ICE in the boot......

Excellent. That exhaust ducting better be 100% break proof for 20 years.

Those units are routinely used on commercial boats. They are very safe - well the proper ones are, I'm not sure about the Chinese ones.

I'm curious to know how the author deals with de-misting the inside of the windscreen of the windscreen in cold weather if he doesn't use the in-built heater. In my experience of driving in cold conditions (snow, ice etc) - you have to push warm air up the windscreen.

Is the pressure getting to Musk? The damage was real, it's his attribution of it to external parties that I'm referring to. Together with his bizarre behaviour during the last earnings call.

Not sure about pressure effects but this guy is very clever, he's got nothing to lose, all the money are from his investors, while he just gets a big salary.

They use very little fuel.

Basically it's a little diesel jet. Combustion air is normally drawn from outside and exhaust air is discharged outside, while cabin air is heated via a heat-exchanger

Heating clean air via a with few moving parts and running under minimal load. So very efficient. We put a D2 unit in a two decked wheelhouse on a largish, alloy boat and it used about 300mL per hour. It was easily heating 25m3.

The set up in the car seemed to be taking it's combustion air from the cabin, and pushing exhaust gas outside of the car.

That air has to be replaced from somewhere. The easiest place to draw air in could be the hole surrounding the exhaust hose. I would seal that and put the fan (no heater) up the windscreen - set to fresh air not re-circ.

Batman: Do they produce much co2?

I just put a 5KW one into my bus conversion/Motorhome. Uses 1-200ml/h of diesel or Kerosene (could easily use biodiesel too?) and warms the whole 35m2 in about 15 mins before dialling back to idle (and this without curtains or furniture to insulate the wraparound windows while I’m renovating it on these cold nights...

NZ$350 with all the bits needed (including a mountable 10L diesel tank) off AliExpress.

Lots of Motorhomers have been running these for the last 2-3 years so reasonably proven technology.

FWIW, the 23mm exhaust is stainless steel, so very unlikely to leak at all, and the intake pipe is meant to be (and pipe was provided for) externally drawing the combustion air...

Not feasible to use a battery powered 12V heater. As a 100AH battery (approx double the size or more of the typical battery in a small petrol car). Will only run a 2KW heater for 15 minutes. Then it will require overnight recharging to get it back to 100% charge. It would also weigh a lot more than that diesel heater. It would also have a lot more embodied energy from manufacturing than the diesel heater.

And using an EV with a diesel heater is still better for the environment than an ICE car.

As for fuel. Ask the local mechanic if they have any old diesel that they need to get rid of. As sometimes they have to drain diesel out of cars that has been contaminated with water, petrol, etc. Which will still burn. But can't safely be used in a diesel engine. Far better to use such fuel yourself instead of that fuel having to be dumped.

Watching one of those natural disaster movies reminding me of the earthquakes. Do tesla power the chargers during these events?

Musk doesn't have a salary. $0.

He's paid in Tesla shares.
