Perhaps they use the heat very efficiently?

Perhaps they use the heat very efficiently?
- sethrin 11y agoNo dice. Conservation of energy and other thermodynamic laws say that [a] there are limits to efficiency, and [b] if you absorb energy you must re-radiate it. Among other things. There's no point in speculating about the blatantly unphysical. @Sharlin is right, it's just "Goddidit" dressed up.
- stevejones 11y agoDo any of them say it must be re-radiated omni-directionally as infra-red light?
- marcosdumay 11y agoPretty much. You can make it cooler than infra-red light (like microwaves), and you can irradiate for half a sphere, or even a bit less. But that's all.
