If cleantech can come up with a storage system that will deliver power at -40F, which is the same as -40C, and recharge also, and still give about 150 miles range on one charge because of the colder temps... this company will be the investment gold mine of the future! People all over the world wish to cut down on polution and will accept "some" limitations and inconveniences. Only time will tell if cleantech is able to deliver in the colder regions of north western Canada and the northern USA...we can only hope and wait!!!

Tesla, the inventor of the world's electrical power system, had a dream of having unlimited electrical power, worldwide, using antennas. This can be done using resonance, similar to how a crystal radio works. Diodes, capable of rectifying the electromagnet spectrum from the heat range and up, need to be used as bridge rectifiers, to convert heat to direct current electricity. The speed of these diodes need to be in the terahertz range and faster. We have the ability now to make diodes that operate in the terahertz speed range. Antennas can be made using conductive graphite paint. Graphite paint is made using nanoparticles of graphite and is black; black absorbs electromagnetic radiation. Antennas could be insulated black concrete, to store heat energy, coated with graphite paint and placed on the ground or on roofs. The graphite nanoparticles will resonate as nanoantennas. Heat is anything above absolute zero.

It is not the speed that dominates for a solar collector, but the wavelength. The bulk of the energy is at one half a micron. Hence the antennae need to be that sort of length. The present way to do it is the solar cell - a diode with a field antenna covering the whole surface where the junction is the feed out of the antenna. Like magic.

Gordon Brown’s trip to the Middle East a few weeks ago was a clear example that non oil exporting states are still very much affected by OPEC’s decisions. While OPEC nations continue to brazenly collude consumers have passed the tipping point and have made concerted efforts to cut OPEC’s impact out of the equation. Consumers have seen the impact on their economy and environment. Politicians have now realized that we will vote for them if they highlight their green credentials, and we know that by supporting locally sourced energy we are developing local employment and business opportunities.
The reality is that it will be hard to finance projects that are purely based on predictions for oil price increases. The entire premise for cleantech is that the technologies are cheaper, faster and more efficient - qualities more sought after in tough economic times. On the whole it will do well, but there will be some serious consolidation as fewer R&D outfits mis-labeled as companies get funding.
Don't forget that there are investors are out there; BP (formerly British Petroleum and now “Beyond Petroleum”) and Chevron have already shown a push towards becoming broader energy companies by investing in solar, geothermal and biofuel concerns. Companies like Monsanto beginning to play in the BioFuels game. Cynics might tout that this is good for marketing, and it is - but these companies understand investment in research and development. They have an appetite for risk, exploration is not cheap, and investing in exploration of different technologies as opposed to new oil wells has a similar cash flow profile.
