global warming

i recently caught a documentary on channel 2 – something to do with green power and all that jazz. It strikes me that while have have come leaps and bounds in electronics genetics that solar power has lagged so far behind. I don't understand why a renewable and clean energy like the sun is not used more. Well actually i do, because its fucking expensive with no real output. While watching this documentary though it explained a few different forms of green power that i had not heard of before which i thought would e nice to share/state just for the purpose of doing so.

We all know what a solar panel looks like – they are usually on top of houses and probably the size of a large piece of cardboard. - but we have these newer panels that have been developed in Australia, about the size of 2 decks of cards side by side, which sit pretty much on a dish similar to an antenna except all the light is focused on this little panel – it produces heaps of electricity, a lot more than you average solar panel.

Another method they showcased was have concaved mirrors which focus their light onto a row of metal pipes. These metal pipes hold water and as the light focuses on it it heats the water up creating steam which turns the turbines and produces electricity.

The last method which is another Aussie invention is s system that produces our own version of taping into nature involves boaring down 200km i believe until we reach a section of the earth which is permanently stuff in a boiling phase due to some sort of radiation that cannot escape. But you know – its good radiation. Anyway basically this system involves putting water down this hole – it heats up and comes back as steam, moves a turbine then condenses back down to water and goes back down the hole – its self sufficient and has is a constant source of energy with no reliance on the sun.

so why aren't these things being put in place now? Government will prefer to spend 7 million of fireworks and and a few hundred billion on a war – but to spend something that would save the world is just ridiculous – don't you think.
