Thinking about this:

- I'll bet inductive charging is bad for emi and pacemakers

- most private electric vehicles will go 300+ miles on a charge, charging doesn't matter to them.

- this might be ok-ish for long-haul trucks, but I'll bet solar panels might work there too (53' x 8' ~ 7kw for solar panels in full sun)

View on HN

A heavy truck uses in the order of magnitude of 100 kW of continuous power for propulsion at highway speeds. Solar panels on the truck can extend range by around 10%, but increase weight, capital and maintenance cost. When trucks are parked, it’s often dark outside.

hmmm.. I checked the numbers and you are right.

telsa semi says is less than 2kwh per mile, so

  2kw*hr/mi * 65 mi/hr -> 130kw

maybe solar panels on trailers would be good for refrigeration, even when parked/dropped, but yeah not too helpful for motive power.
