      As for pumped hydro, take a look at Banks Lake and Grand Coulee Dam; existing for years. Also take a look at Hawk Creek and Lower Crab Creek in WA state as pumped hydor storage possibilites. What lands do you think the BLM have been buying for years?

      John - right on re. response to Doug with diesel hybrid and the cheapest longest life (lowest life cycle cost) batteries.

      I only dream of the biodiesel injected burner with no moving parts and solid state waste heat recovery devices directly powering the Chorus Motor with the only on-board stored energy device being a GRASS TANK. Two manybe three years away.

      John - with all the other variable and flexible demands during the day one does not need the demand that EV's provide off peak.

      John - OK, so the rich buy pure EV's; good. The masses will go for normally priced vehicles called hybrids and 200-300% increases in economy with unlimited range which you don't seem to dis as much as expensive pure EV's with better economy but limited ranges; and the rest buy scooters and bikes, or in addition to the others.

      But, again, as for storage on the demand side of the equation, which you don't wish to address vis-a-vis generation and inbetwix surge storage capicity, EV's may provide some demand sponge flexibility, but something like commercial and industrial refrigeration using insitu storage permitting significant flexible demand at point of use is being overlooked (not unlike making ice or additional cold salt, etc., when excess power is available, and "melting" the ice when demand power is peaking). Do that all over the US in major ciites and industrial complexes, the same places that create the demand. That's just refrigeration. Now look at other demand loads that can be shuffled accordingly. Try heating. HVAC? Things where we don't even lose the inefficiencies of charging/discharging that batteries, flywheels and other stored enery devices inherently contain (internal resistances, overcharging and unrecoverable disassociation of gases, etc.).

      Now, you may say that those or enough of those systems cannot be turned on and off quickly enough (shut down and started up too much), which may be true currently (no pun intended), but with the advent of the applied computer/communication... technologies and ability to monitor and control millions of systems in a variety of ways, utilities will be able to not only reach in and turn off residential refrigerators as well as commercial and industrial loads in a fashion that no one will notice, but not even the refrigerator or the other loads will find it strange.

      We have computers controlling the turning off and on of up to 18 harmonic phases of 3-phase motors, and the motor doesn't care. In fact, that control ability makes a 20hp motor deliver the low speed torque of an 80 hp motor. That's good. Point being, the computer controls the number of phases turned on and off for a 60hz motor. Is that fast enough for your repsonse times? Frequency regulation?? Within 60hz? At the final load, the end user.

      Alternative Energy Storage: Why Frequency Regulation Is Important
      John - one does not want to spin steam - that is like having your ICE idling while stopped in traffic: come on EV's!

      Here's how to do both on the demand side. Real data.

      Right, one-trick pony; the other ponies, the real demand control technologies will more than likely render current regulation "adequate" as the real manifestation of variable generation is sucked up by control of variable demand at the other end. Humongous surge capacity may indeed not be necessary. Certainly, the goal will be to minimize it as in any good business: excess inventory is a negative.

      PS - just to keep the EV folks happy, recharging batteries at night at home are included in the demand control equation.

      You covered generation and storage, and to some degree, demand; however, we may have many opportunities to regulate (control) demand, including the regulation of bulk storage (pumped hydro, etc.) with variable continuous (speed, etc.) and flexible incremental loads (number, etc).

      And, significantly, future smart metering and control of demand (loads) in residential, commercial and industrial HVAV and lighting (non-critical process demand) to refrigeration and local storage provides opportunity we have not begun to wrap our hands around.

      PS Jonesbury - burning is an oxidation process; freely in "air", or reacting with other chemicals with or without the help of a catalyst in a fuel cell or recombination device, or combining with oxygen in a chemical rocket engine.

      You are almost suggesting stripping hydrogen from methane to then burn the hydrogen - when when should just burn the methane at no additional enegy input or cost - unless the application justifies the additional cost (such as needing hydrogen for it's specific impulse in a nuclear propulsion system in outer space).

      jonesbury - what you miss in "wasting" solar, wind, and tidal vis-a-vis all the other energy sources (well, throw in geo and hydro too), is that the actual energy cost is zero compared to the cost of idling oil, gas, coal, wood, generation, etc. So, idling production, or generation is just underutilization of the capital and some of the operating costs, but certainly not the fuel cost. Ya know, it's like letting your gas guzzler idle at the stoplight V/S the pure electric or hybrid actually shutting off; or better yet, the solar PV rooftop driven car stopped at the stoplight. It's just missed opportunity, not waste.

      Hey all you financial wizzards of Wall Street - how's this for paying off the costs of the $750 B bailout and following that, our Trillions of national debt:

      Don't puke, now: just listen up.

      Let's have Uncle directly take 1% of the 2%(+) of total assets that all financial management firms take from us as management fees and apply it to the Nations' debt. It's really our money, first. The firms take the 2% whether they make of lose money. It's a win-win. Pays the debt AND CUTS EXECUTIVE COMPENSATION (a form of "legal" white collar theft).

      It is a myth you know, that we have to pay lots to get the best managment. The proof is overwhelming.

      And what's best, we Joe Blow's won't feel the pain.

      Right on Mark Goldes - and that no-moving parts BIOFUEL INJECTED BURNER incapsulated with solid state waste heat direct conversion to electric devices powering a 20-40 hp electric motor with the only onboard energy device being a GRASS TANK, will not only remove the Houston noose from around our necks, but also whatever is left of the Detroit noose.

      jonebury - making and storing Hydrogen to then burn it is a waste of energy and money.
