Over the past year, I’ve had thoughts of building some sort of solar hot water heater. In fact the seed was planted well before this year. I lived in Israel for about 2.5 years ending with the end of 2000 when I moved to Oregon.

One of my apartments there had one and it meant that my electric water heater was off all but 3 months of the year. This was inspite of the fact that I took my showers in the morning.Anyway, we got a swimming pool last summer. It’s a collapsible pool about 15′ across and 3′ tall and it often seemed a bit cold, hence this project. So I’ve been doing a bit of surfing on the topic on da web and while I didn’t come across much, I did find some DIY project at this site. In particular this project which uses a big industrial looking press to form collector absorber plates got me thinking. The thing is I don’t have a press and don’t have much other need for one. So after thinking about it a bit, I decided to try using the weight of my pickup. Note: each of the pictures can be clicked for a larger version. As you can see from the pictures, I just took a couple pieces of scrap and build a simple form. I then just drive over it. A couple things to notice:
