As part of my secret plan to raise the standard of "Impossible Ideas" on Brainstorm - I want to keep setting people's eyes higher.

And this is particularly off the back of the comments on my last "Impossible Idea".

I propose Ubuntu solve the Global Warming crisis.

Obviously this needs to be broken down into a series of achievable steps:
1) Better power management in the kernel.
2) Merge rival projects such as [Ubuntu, Red Hat, Debian, Suse] and [Linux, BSD, Solaris], a bit like Compiz-Fusion. This would relieve the planet of a lot of "hot air".
3) Make powersaving and economical decisions as standard on Ubuntu - e.g. single rather than double clicks for files; dark screen colours by default; oh and supply thermocouples as standard on Dellbuntu machines to produce electricity from waste heat.
4) How about a new official derivative of Ubuntu that runs purely on Hydrogen, called, Hybuntu?
5) Finally... there's a button on my laptop that can turn the brightness down. Ubuntu has had native support for this button since Dapper. Build such a button for lowering the brightness of the sun, and develop native support for this button in Ubuntu.

Due to the hardware requirements of this idea, I stuck it in Hardware Support.
