: Hello John,

: great idea. I may have the same problem here in Germany - temperatures are
: falling. My question: if there is no solar energy, how do you heat the
: tent?

Joachim,

I'm in Denmark, and the temperature is dropping here too.
I was thinking of setting up 2 or maybe 3 indoor working-halogen-spots like : http://cgi.ebay.de/ws/eBayISAPI.dllViewItem&item=2953426260&category=19591

I had 2 of theseon the floor, when i put up new wallpaper and painted my apartment, and they will easily heat up 20m2's indoor. Maybe not so much outside, but if you use the "tent method", i'm pretty sure you will get the heat - and light - you need.
