Some time back I posted a query about dirigible/blimp control surfaces.
Now I have another query- could a helium filled airship control its
lift by having some internal heat delivering device such as an electric
radiator.

I'm aware hot air balloons generate lift by heating the enevelope with
LPG flame. Could sufficient expansion be delivered by an electric/non
combustion method?

cheers
