Aeronautical Engineering/Thermoelectric balloon

Question
Thermoelectric hot air balloon
Thermoelectric hot air  
I have had an idea relating to the production of water. It's a few expertise disciplines but I thought I would start here.

The basic premise is to create a hot air balloon using a thermodynamic fabric powered by a solar cells with the intention of the current creating a hot interior envelope for lift and cold exterior skin.

Condensation would form on the outside dripping down into a collection tube.

Please find attached very basic diagram.

I'm interested to know peoples thoughts on if it would fly and if the basic theory would work.

cheers

Tom

Answer
Sounds interesting...  you probably need to run some feasibility numbers ... basic things like weight of fabric, insulating properties of fabric, energy load, weight of solar cells, etc...

You've got quite a few design issues to look into, but given a large enough size and material properties it could maybe work (I don't know about the water collection part)...  but just as a hot air balloon...  you could run out some quick numbers to see if it's at all feasible
