I think Francis is in the Philipines, which have a hot humid climate, the most difficult for thermal comfort. It's probably the one location on earth even I wouldn't begrudge someone an air-con 8) Yes, I'm in the Philippines and the climate here is pretty hot...since summer is now approaching, we a...

Alternativly perhaps you are considering a standard grid powered A/C unit, with some or all of the energy used being offset by a grid tied PV system. This will be a cheaper and more efficient system, but has three pitfalls 1) it is totally grid reliant, and gives no backup supply whatsoever. No gri...

This is also a brilliant idea. I think even if we don't have solar powered phone, we can still use a solar charge controller and charge our phone using it.

I think this solar powered cell phone is brilliant! Although the energy used by cell phone is so small but if many people will use solar powered cell phones, then I think we can all save energy significantly.

Hmm this is interesting. I haven't tried using wind power for electric heating yet. So far, the only renewable energy I have tried is solar energy. But thank you, Adam! I am intrigued to try wind power, too!

Have you heard about solar powered air conditioning? I think this is a cool and brilliant idea. Although I don't have solar powered air conditioning yet but I'm already planning to have one. What do you guys think about this?

I think this portable solar generator is useful for short-term use only because I think they are not that durable to use for long periods of time. However, I like this solar generator because they are handy and portable. I have a neighbor who have a solar generator like this one and they always brin...
