Re: electromagnetic defrost heat pump?
It's similar, but I don't find any mention of using capacitive discharge to create tiny "steam explosions" to blow out loose frost. I think the design I've heard of would be even more efficient since some energy used physically blows out frost instead of melting it. (It takes much less energy to move a given amount of frost a short distance than to melt it.)
