Don,
If induction plates are so efficient and if one is patient enough, why can't an induction plate be operated at low wattage settings so as to be about equal to a regular hot plate in rate of heating .... while then being quite practical to power them when drycamping with inverters, large battery banks, and solar panels?
Hence, do induction plates used at lower settings make possible drycamp cooking without using one's propane supply?
IAW, you seem to talk them up with regards to being faster .... but how about them also being better misers of precious electrical power?
