    The sketchy unreliable performance of wind and solar as Grid Energy Sources could be overcome by applying to applications that made more sense.

    Trying to manage and plan backups on the grid for these renewables has proven to be costly and inefficient.

    The Thread "1st Priority" http://www.usmessageboard.com/856374-post1.html

    -- got me thinking about HOW they could be put to uses that were NOT time critical but truly solved some energy intensive problems.

    In that thread the poster suggested Desalinization Plants as an application for renewables.

    Any time you can identify an energy intensive -- non-grid-tied application that does NOT require CONSTANT 24/7/365 power and where the product is STORED (like fresh water)
    that's a technological winner!


    Right now, wind and solar would NOT play a huge roll in developing an Electric Vehicle fleet because of their spikey delivery of power. But Fuel Cells are a mature technology and the PROMISE of running them cleanly on Hydrogen COULD BE MET -- if the Hydrogen factories were powered from wind and solar. Right now -- fuel cells suffer from a bait and switch problem where they are played up as cleanly running on hydrogen and producing only water vapor as a by-product. But in reality -- most large fuels are running on NAT GAS -- a fossil fuel and there is not a source of hydrogen for general transportation because of the price of electricity to produce it.

    Put the hydrogen factories in locations OPTIMUM for using local wind or local solar or both. And suddenly -- we got an option for transportation energy.

    Same opportunity for water system pumps. LARGE urban useage of power required to move clean water around. THIS -- as an isolated system might even work in less than ideal locations with adequate excess generation capacity built in.

    Any other NON-GRID ideas that would provide a large chunk of power? I'm pondering writing an article... Give ya full credit..

    Fresh water is stored in ponds and buckets. Solar power is stored in heavy batteries made from extremely toxic chemicals and a manufacturing process that uses lots of energy and produces toxic by-products that sometimes find their way into the environment. That's a technological nightmare that warmers choose to ignore.

    The trick is to find applications where the RATE of production can be variable. So that on good wind day -- you're producing twice "normal".

    Besides desalinization, urban water storage and hydrogen production ((where the product is stored and the delivery rate is buffered)) -- you might find that biofuel production, algae fuels could be made feasible by lowering recurring energy costs.

    THe battery wastestream would be incredible if EVERYONE chose to store it. Just having a couple million EV is an enviro nightmare. Hazmat response to EV crashes is not over-exaggerated.

    "The trick is to find". "If only". "Maybe someday". "Scientists imagine". How many more cliches do we need to hear while we are mortgaging our grandkids future to oil producing countries?

    Isn't it convenient that all those who profess the need for more solar, and wind turbine energy sources seem always to forget the Environmental disaster unfolding in China from the byproducts of the construction of these wind turbines, and Solar panels... I find it decidedly inconvenient that they ignore the pollution problem simply because it is not in their back yards.

    How about low yield unused oil wells where it doesn't pay to run the pumps off the grid? I think solar and/or wind could be useful for systems that are not schedule or time sensitive.
    Pumping irrigation water to holding tanks, perhaps

    Net Zero Electric housing project...
    :clap2:
    The winning number is zero at this housing site

    Yeah -- that's like the cities that claim they are "powered by the wind". Let's disconnect them from the grid and see what happens eh? This net zero housing development is gonna be awfully dark and cold at night. But it's not THEIR concern where the electricity comes from is it? They are in the Energy Business and They will make a profit (after 12 years of finance payments and if the cost of repairing the roof doesn't bankrupt them).

    Well yes, you are stupid enough to wish for that. And when China makes to breakthrough on really efficient solar, we can all buy the panels from them rather than invernting them here and manufacturing them in America.

    30-MW and 20-MW Solar Power Projects for China (in Xinjiang Region) - CleanTechnica

    As just noted the other day, China has upped its solar power goals again. Here’s one big solar power project that will help it get to its new goal of 21 GW of solar by 2015:

    “The government of Bole city, Bortala Mongol Autonomous Prefecture, Xinjiang, China recently signed an agreement with Hubei-based JCS Solar for a 6 billion yuan (US$948 million) photovoltaic project to be located next to the area’s Sayram Lake,” Liu Yuanyuan writes. “Construction of the 13 million square-meter facility is expected to take three years. Phase I of the project is expected to yield 30-MW of capacity and connect to the grid when completed by the end of October 2012.”
