Stewart Brand Proclaims 4 Environmental ‘heresies’
http://www.ted.com The man who helped usher in the environmental movement in the 1960s and ’70s has been rethinking his positions on cities, nuclear power, genetic modification and geo-engineering….

Brilliant talk.?
Adamredwine’s view on viable energy sources is extremely biased because he is a nuclear power professional. His livelihood depends on nuclear power surviving as a viable energy source. While I would hate to see his livelihood damaged, I would rather the world make better decisions and improve the livelihood of all inhabitants and not just the ones that have? great vested interests in themselves.
This is an ad hominem attack. It is stupid. We? can just as easily throw it back at greenies.
In the world of motor vehicles, the weight-to-power ratio becomes significantly important. Electrical energy can be stored? in the way of fuel cell technology which is an energy dense fuel source, which is ideal of vehicular transport.
A bountiful amount of CSP can be produced both locally and transnationally, distributed by an updated smart electrical grid (ours is almost 100 years? old) which can store energy during off peak hours and release it when we need it most. The energy can be stored in electrical, mechanical or chemical capacitors quite efficiently.
Solar energy is our very own? nuclear fusion energy, and it has supported all life on earth for billions of years. As long as the sun burns and we have access to it, solar energy is boundless (and if the sun stops burning and/or we lose access to it, well then we’ll talk about nuclear fission plants :).
Collected Solar Power (CSP) is cheap to make (does not rely on expensive Photovoltaic technology but rather parabolic mirrors and Stirling engines that can produce both electricity and hot water at? the same time), so cheap that it is competitive with fossil fuel energy in terms of its cost-to-energy-output ratio with one enormous difference. IT IS SUSTAINABLE.
Nuclear power is cheap, but nuclear power plants cost too much (manpower, raw materials, hazards to populations, etc.) to be feasible, not to mention the carbon footprint it leaves in its creation. Furthermore, the amount of nuclear fuel remaining on earth, whether? it is 20 years or 600 years worth, is ultimately limited and the energy paradigm would require a complete overhaul at some point in the future.
No the biggest problem is southern white male racists supporting right wing psychopaths, lucky? that doesn’t apply to you eh?…
wow, you are? fucking stupid. did you not listen to the talk? immigrant workers have nothing to do with it. child reproduction eventually decreases once within cities. besides, there is the benefit of cheap labor that in turn keeps costs down.why don’t you read something that isn’t far right propaganda?
