I got to visit the Bali Appropriate Technology Institute last week and filmed this DIY solar water heater:

It could be improved by making the top easier to take off so the wood or gas-fired option would take less work to engage, but the idea is sound. The water was warm even though the day was overcast.

What is inside the barrel that makes the water flow out?

I like it. A LOT. There should be a way to control the wood fire (small J tube rocket maybe) so you don't need to remove the solar collector.

Yeah, absolutely. That's how I would redesign it.

Water temps were into the 30s, Centigrade, and it was overcast.

The weather in this location was cool rain forest. Very pleasant but humid. Overcast the whole time I was there. Not sure about all year, though.

Hey David,
Thanks for the video. I may have to pay Pak Alit a visit... Am living in East Bali since 2010 and had never heard of that place!
I'm using a commercial solar water heater system with vacuum tubes and a rooftop water tank here and it's way too hot for this seaside climate. Water boils on hot afternoons and you gotta watch out for burns when opening the taps.

I agree. Here's the link: http://stoves2.com
