I'm not giving up on thermal, just want to know who is currently up and running with a viable business. ------------------------------ Dan Antonioli Owner Going Green Dryden NY ------------------------------

Has anyone recently written any articles about the current state of solar thermal? I'm a big fan and have had several systems over the years. I have two projects coming up where thermal would be an excellent fit...but getting information from any of the companies offering thermal systems is less than ...

Thanks Elias. I've downloaded the Fraunhoufer article and am reading through it carefully. I'm on a mission to get as much clarity on this issues as I can. "Energy payback" is a phrase I've heard many times and of late find both intriguing and troubling, mostly because the metrics are not defined and ...

For example, with a pv panel there is embodied energy that goes into making the panel. Because the panel produces ...

Finding a way to grip the rod/pipe so you can turn it and loosen the point of insertion is the biggest issue here. But I've got a couple of ideas for a grip that distributes the ...

I'm being offered a presumably great deal on a four year old evacuated tube system (SunMaxx) that is in bad shape. Many of the tubes didn't come out of the manifolds properly and the soft copper rods are ...
