Some (random) thoughts on renewable energy.

Nuclear, solar, wind, wave, geothermal, fusion, tidal, “clean coal”, geosequestration, hydrogen economy, global warming, energy storage, fuel cells.

This is complex stuff. Getting it right will, just possibly, preserve the climate within familiar bounds. Getting it wrong – well who cares somebody else, some future generation will pay the price for our mistakes / greed / apathy, so why should I really care?

One of the problems oft pointed out about many sources of renewable energy is that it is not reliable. The sun does not always shine, wind blow or waves run with the power to generate electricity.

OK, so my question is why not store the energy?
Use wind power to pump water uphill in the snowy scheme. That way your not using off peek coal sourced power to do it, your getting it from a renewable.

Why not use renewable power when it is available to generate Hydrogen from sea water and store it for use in fuel cell vehicles? Wind not blowing?, sun not shining?, that’s ok because you have stored enough Hydrogen to get you through.

No water – no problem, just desalinate using wave energy. Perfect solution – the energy is at the point you want to use it. Use high pressure air forced into a tube by wave action focused using a parabolic wave reflector and you have a very low maintenance source of high pressure air that you can use to push sea water through RO membranes.

Roof tiles with solar cells, passive housing and building designs such as better insulation all make a difference. Anyways lunch is almost over so I’m back to work, but please poke around these links:

Update - 28th
Firstly, sorry for the ramble.
Thanks to 'Brian', presumably Brian Meano, CEO & Founder of Fieldstone Energy, Inc. for his link to on a similar technology which I will drag onto the front page here.
I also caught up with a whole bunch of Radio National podcasts that I'm linking to the transcripts (the podcast get taken down after a month but be quick and you can listen)

and then there is all this stuff on Ockham's Razor that I've been reeding past my bedtime

We do have the capabilities in which you are referring. The technology is Fieldstone Energy's patented technology. It is a continious source of power which can connect to the grid synchronously. It is the only technology of its type. We do have a viable alternative to wind and solar wich will has a place for a sustainable future.
