Last week I converted our showers to the Ecocamel showerhead. How to reduce the volume of your shower water from 15-35 litres a minute to 7 litres. Crap shower? Not really because the showerhead pumps in air and mixes it with the water for a spa type effect. Result - same level of flow but offering savings in water and heating bills. Quite ingenious I thought and not at all expensive.
A good opportunity to mention generous.org a spinoff from Greenbelt festival. Basically what you do when you join the Generous community is sign up to try 1-2 generous actions a month. You can use the site to see which actions are the most popular and ask questions. You can also get and give feedback on which actions are difficult, fun, smelly or just plain bizarre. Now that online communities are all the rage - it is worth tracking those which set out to have a point.
