| - | As part of my solar airconditioner I am working on a project to use the sun to boil water. | ||
| - | V2 is a $5 kmart glass jar with a water bottle inside. This is surrounded by a reflector. | ||

| - | **Key Discoveries:** | ||
| - | |||
| - | The glass jar does not get hot despite being in the sun. | ||
| - | |||
| - | The drink bottle is almost boiling the water. | ||

| - | I started with 800ml of cold water. | ||
| - | |||
| - | At the end of the day I had 740ml of almost boiling water. | ||

| - | I have decided to go with a flat panel design to get more energy. | ||
| - | However my solar collector pipe has sprung a number of leaks. | ||

| - | After a lot of research I have found that the water only needs to get to 50C and not boiling. The new design is to lay a number of coils of black pipe on the roof to get the heat. And even on a cloudy day the water gets to a reasonable temperature. | ||
| - | |||
| - | Now I just need to add more coils to get the temperature up higher and build a way to get it back down to ambient. | ||
