I am always interested in new technology for storage of energy. I was very happy when i know about fuel cell and advancement in solar cells. But it takes too much time to make it easily available for common people. Now the nano technology is good but i don’t know when it will be easily available for common people and how much will be the price? I am also interested in news updates for batteries technology.

The Idea of reducing the energy we use is definitely a good one. There is however one big hurdle – not many people are ready to give up their way of living… Almost no one is ready to give up the big house and use an apartment 50sq mt big, only to be able to use less energy. So, for now using green energy and developing the systems which do not pollute is a very good alternative at an acceptable price. First step… Many to follow.

Are there no people considering other plausible possibilities? Why not build ocean current turbines not unlike underwater windmills to generate electricity? As an Australian, I would like to see the idea implemented here between Tasmania and Victoria’s almost continuous thrashing waters.

Shell is going to be in a big trouble unless something original is done to bring down the cost of oil with fellow oil producing companies. The cost of oil is going to get a lot cheaper with time as a result of the present day alternative sources of energy. With the present day biofuel that can be used in aircrafts, the future is very dim. Alternative incentive could be made with the European union and their contemporaries to get something original to the sales of crude oil. The new target should be in the west coast of Brazil, and the east coast of Mexico.

I agree with Wilf. There’s an analogy with building highways and how that has the net effect of increasing traffic. For energy systems, new supply leads to increased consumption, increased demand, new supply ad nauseum. While I look forward to better energy storage technologies, such as nano-tech based batteries, I know we have to consider the cradle-to-cradle environmental costs. Nano-tech batteries can have much longer lives/extended recharge cycles due to tailoring receptors to the ions, reducing fracturing; there are other benefits, too, such as increased energy density. BUT, as Wilf points out, we have to reduce our own energy intensity. That includes accepting electrical supply not meeting demand sometimes, with brownouts and even blackouts; reduced mobility and independence in travel; and many other reductions in our so-called lifestyle. As I said at an Ontario Hydro hearing a few years back – “Melt my ice cream!” Far preferable to the ongoing catastrophe of climate change.

While such new technologies are being developed are we also ensuring that we are developing “whole of system” efficiency models that include all externalities? It seems to me that we are hell bent on marching forward without understanding the relative efficiencies compared to low entropy but highly polluting energy systems that we currently have. If the efficiencies are significantly less but more ecologically sound then surely we need to integrate such technology breakthroughs with a concerted effort to contract overall energy consumption (ie if we try to meet existing energy demands with less energy efficient alternatives then the processional effects [bless Bucky Fuller's profound wisdom]) could have dire consequences. When are we going to start focusing on living less energy-intensively in concert with the technological advances?

I’m keen to hear peoples thought and feelings on this.

Cheers
