I’ve put this together quickly as something that will hopefully be useful for occupybristoluk (twitter web)

The bike cinema kept getting broken because it was being used for a purpose that it wasn’t designed for. After talking with Chris and Gustavo we came up with a set of upgrades that would ensure the bike cinema keeps working!
- battery isolate switch for storage,
- toughen the insides to make sure it survives regular transport,
- audio output jack,
- battery charging socket,
- easy to change DVD hatch.
I was just reading about river simple’s hydrogen car - a really excellent concept. Not only is it a breakthrough in technology (50% efficient at recovering energy lost through braking), it’s a breakthrough in car ownership.
Their motto is ’sustainable mobility’, and this is achieved by leasing the cars rather than selling them. This puts the focus on long life and low running costs, both positive things when it comes to sustainability.
Finally, the whole car is an open source/open hardware project! So people are free to build and modify their own versions - much like our own projects here at openrenewables.org.uk
Check out the latest update to the wiki: a DIY solar rainbow maker! For £10 you can get everything you need to build a cool solar powered rainbow maker. It works by collecting energy from the sun and using it to turn around a lead glass crystal. When you the sun shines you get cool rainbows moving round the room!
I’m excited, pleased and proud to announce that I’ve been awarded money from UnLtd!
The money will go to pay for the development of the modular bike charge controller and the open charge controller project, which will make it easier for us DIY green hackers to create renewable energy systems.
We had a launch of the bike cinema, and I’m pleased to say it was all working after the Glastonbury blowup. The system is more robust now and ready for use in the cafe!
