Build yourself a Solar Heater
Lifehacker.com have posted a nice video demonstration on how to build a cheap, less than $10 is the claim, solar heater out of foam board, black paint and various other materials than can be collected together cheaply. According to the video, once you have built it, you can put it by the window and increase the room temperature by at least 10 degrees. A good one for the greenhouse perhaps? $10 dollars is less than a fiver these days.
If anyone builds one let us know, especially if it is for less than a fiver!
