Attached is the newly-updated concentrating solar section from Chapter 4,
Plank 1 of the Renewable Deal. It has all the current technologies
explained and a catalogue of U.S. concentrating solar plant installations
underway or existing. Later updates of this section will fold in
the Scientific American article which demonstrates that a sizeable
portion of the U.S. energy supply can be provided by concentrating solar
plants in the SW deserts, with the juice bussed across the southern U.S.

These solar systems don't use water. They are "closed loop" systems that circulate a heated fluid. The other day on CSS there was a good article about electric cars being developed in Israel. One of the problems with where we live is the inability to export solar generated electricity because there is little electric transmission here in Southeaster Utah. What a great combination - solar generated electricity that is stored locally in electric car batteries. We could become energy independent with a decentralized power system. Another piece to the puzzle is the "barefoot university" in India that is training people with no formal education to build and install solar systems. Just as there is a "local food" movement, we could also have a "local energy" movement. It's high-tech low-tech and sustainable.

Thanks. I have forwarded this info onto Drew Sitterud and Jeff Horrocks, Emery County Commissioners. I have had some luck in talking with them about looking at solar options rather than nuclear for their Green River Industrial Park. If we can keep feeding them leads we may not have to defeat nuclear, just support responsible alternatives. They really just want an industry and I'm trying to convince them that nuclear is NOT a good bet economically due to long licensing requirements etc. Let's give them an option!

We need energy solutions, no question. The nuke option for Green River has many problems, any of which will kill it: (1) the amount of water needed, (2) lack of transmission lines, (3) public opposition, (4) the high cost, (5) lack of adequate nuke waste storage, and (6) transporting nuke waste. Once those minor issues are resolved, it will be clear sailing - yeah right. The "Do Nothing" option continues the burning of coal, creation of greenhouse gases, and climate change. "Doing nothing" is a decision to keep doing what is not working all that well. The central large scale solar alternative has it's share of problems too: (1) environmental impact on the desert, (2) transmission or storage, (3) cost, and (4) public opposition. Distributed solar combined with energy efficiency, alternative transportation, smaller homes, and sustainable living is the best, least costly, lowest impact option. Unfortunately, it's easier to promote big, single solutions that solve everything - nukes, concentrating central solar, etc. As long as the problem is described as the need for big solutions, we will only have burning coal, nukes, and large scale concentrating solar as the solution. We really need to re-define the problem to get to the transformative, sustainable solutions. On Oct 8, 2008, at 1:27 PM, Audrey Graham wrote: Thanks.

The closed loop fluid feeds into a heat exchanger which then
boils off water, producing steam, which turns a turbine. So, yes, they do use
water in the same way that a coal fired power plant does. Chris From:

Actually there are 4 or 5 ways to use concentrated solar to produce electricity. The ones that don't use water are concentrating solar on photovoltaics to directly produce electricity and the Stirling engine - basically a heat driven piston that spins a generator. There are also experiments with solar chimneys that are combined with greenhouses. The rising heat in the solar chimney generates electricity through a wind turbine. As Chris has noted, the other concentrating solar systems create steam and require water for cooling just like a coal plant. Since water is an issue here in the desert, it seems the non-water using options are more viable.

So we need to figure out a way for local governments to see the benefit of small, dispersed solar in terms of jobs and revenue. We need to restructure where and how subsidies are handed out....otherwise, with the set-up now, it is only the big centrallized facilities that generate tax revenue for local gov. And those taxes pay for the general infrastructure of everything from senior services to jails and courts to animal control and children's vacinations (ie "government" is not the greedy enemy here). We need a new plan!!

Good idea to have a new plan! On the water issue, power plants are typically huge users of water. Here's an article over the water right fights for the IPP power plant in Delta, UT. It's a gigantic operation. The Ely Times - elynews.com :: News: Generating as much controversy as power As originally planned, the 3,000-megawatt Intermountain Power Project (IPP) would have needed up to 45,000 acre-feet of water per year. The fighting over water rights was bitter - farmer against farmer. Green River Nuke Plant TransitionPower Development LLC, signed a contract to secure the rights to nearly 10 billion gallons of water a year to be used in a nuclear power plant. 10 billion gallons is 30,689 acre-feet of water per year. One acre-feet per year is about what it takes to support a family in Utah, so that's enough water for over 30,000 families. Water rights will be bought from farmers in the region, so if anyone believes water is scarce now or it will be in the future, this will take away from the region's ability to farm and live. Moab and Grand County may be stakeholders in this proposal if there is an impact here. Another issue is power transmission lines. We just don't have the capacity here to transmit power from 2 large nuke plants. No one is building new transmission because there are no profits in doing so. This happened as a result of deregulation. It could only be done with massive federal investments. New World View We need a new model for success, a new sustainable based world-view that has public support. To do that will take more democracy, more town meetings, more creativity, less gridlock, less polarization. - Craig ------------------------------------- Craig Hibberd 435.259.1610 On Oct 9, 2008, at 10:54 AM, Audrey Graham wrote:

That's plan with a capital P! Thanks Audrey. This is what I was getting at in my comments on the waste pits; that Grand County needs to invoke a General/Sustainability Plan that requires ALL land-use planning and decisionmaking approvals to be filtered through. Proactive planning for sustainability, based on real-world trends and a visioning process, would by its nature inherently restructure the subsidy/revenue/infrastructure process, and would further ensure a transition to local, revenue-turning economies that protect community interests rather than cater to (or fall victim of) outside developers and extractives. At present, we are still reactive, making decisions on an ad hoc basis (or simply abdicating them), with little to no applied standards for community sustainability, self-reliance, and long-term health. Communities that fail to empower themselves (on a regional/watershed basis) become industrial sacrifice areas.

Later updates of this section will fold in the Scientific American article which demonstrates that a sizeable portion of the U.S. energy supply can be provided by concentrating solar plants in the SW deserts, with the juice bussed across the southern U.S. from the east to west coasts through use of high voltage, low-loss DC cable technology. > > > > > > > > > > > > > > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Canyonlands Sustainable Solutions" group.

The only water used in the concentrating solar generating system is in the secondary turbine loop, which can be designed as a closed loop system. Thus, the amount of water required to operate the power plant is the amount needed to fill the secondary steam turbine loop. This water is then used over and over again, as it circulates through the hot salt tank to be flashed into steam, thence through the generating turbine, thence through the cooling tower which you can think of as a giant automobile radiator where the steam is cooled back into liquid state water which then flows back into the hot salt tank to be turned into steam again. The only loss of water from the system would occur if the system blew a gasket and leaked. The circulating fluid in the solar collector primary loop system in the plant is high temperature oil, not water. -Lance At 09:03 AM 10/8/2008, you wrote: >But doesn't this type of solar power require huge amounts of water?? > >Audrey Graham >435-220-0185 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Canyonlands Sustainable Solutions" group.
