Excellent method for heating your water off the grid. This method is not only very efficient as it uses what would otherwise be waste heat being directed out through the stack, but it also works in much the same way as a hot water on demand system or a solar water heating system. This concept can even be directly incorporated into your current solar water heating system or as a separate stand-alone in the kitchen or workshop. Keep your mind open and remember to improvise!

SolTech Energy: Nothing says "afterthought" like a rectangle of solar panels slapped onto the roof of a house with no visual relationship with the rest of the structure. Swedish company SolTech Energy brings solar in a different direction with their roofing tiles, made from ordinary glass in the shape of (gasp) ordinary roofing tiles. Why has no one thought of this sooner?

The ice fountains of Enceladus Fountains of water ice blast thousands of kilometres above the surface of Saturn's tiny moon Enceladus. It is thought that the pull of Saturn's powerful gravity distorts the moon and heats the interior, forming an underground ocean. When this reservoir of water contacts the vacuum of space it vaporises and explodes above the moon. Any liquid water freezes instantly. Images of the ice fountains were first captured by the Cassini probe.
