Thanks! I just went to back to the old fashioned stove top/firepit percolator! Good as I remembered from 50 years ago!
What is the most energy efficient means of boiling 8 oz of water for tea or coffee in a van powered by Li batteries?
1) Put a glass cup in a microwave oven,
2) Use a kettle on an induction burner,
3) Use an electric tea kettle?
I'm trying to decide on an approach to making coffee/tea with the minimum amount of space-occupying equipment and minimal energy consumption.

My understanding is the electric power contains a fixed amount of energy, eg heat, so how can an immersion heater in the water itself be less efficient that an induction burner that is outside the container?
It can't.
An immersion heater is 100% efficient at transferring electric power to the water. (of course, the water is at the same time losing heat to the environment, but that is a different issue).
Despite the setup mentioning nuclear power etc, the actual article only considered a few of the many alternatives. I do not believe they ever mentioned immersion heaters. Nothing will ever do better.
Immersion heaters are effective, but please make sure you never plug one in without first immersing it in water, and make sure it never falls out of the water while in use. In other words, when using an immersion heater, watch that pot (or cup) like a hawk. A plugged-in immersion heater that's not immersed can be dangerous in the extreme.
I am certainly not going to argue against this advice.
However, any modern UL-approved immersion heater will have a built-in thermal protection device (a thermal fuse at the very least). So, they are not as scary as they used to be.
Never, EVER use a non-UL-approved (or equivalent) appliance of any kind.
