The Sept. ’06 issue of SciAm is a masterpiece, laying out a paradigm to understand how to bring carbon emissions under control. See www.sciam.com. Here’s my letter to them:
Congratulations for putting together what our governments have failed to do: a framework to understand and solve the carbon emissions problem, and thus, save our planet as we know it.
Some comments: You mention both high concentrator solar power and themochemical separation of water (albeit nuclear-based) to generate hydrogen, but did not put the two together. There is some activity in direct solar hydrogen generation that deserves serious funding to see if its scalable, as it just might power the hydrogen economy with renewable energy.
Also, dismissing cold/sonofusion as “entertainment” closes the door on what could possibly be the silver bullet. There is good science being done in the field and none can say it is impossible, lest we practice ” Pathological Disbelief”. Even if the chances are slim, the rewards are great. It also deserves some real funding as every dollar would be streched to the maximum by many qualified researchers.
Lastly, thanks for presenting wind power not tied to massive towers (the key to its future), but your illustration of a laddermill in an urban setting is not a safe deployment.
