Science/Tech See other Science/Tech Articles Title: Hydro can meet most of today's power needs Yahoo... Present CC is reversible and we can control climate YOU MAY NEED LOTS OF POWER FOR DEVELOPING WATER SUPPLY NETWORKS. HERE IS THE METHOD TO HARNESS POWER AS MUCH AS YOU WANT, THEORETICALLY UNLIMITED. II. SOLUTION TO POWER CRISIS: RUNNING TURBINES IN SERIES LIMITLESS SOURCE OF ENERGY (BLUNDER IN HYDROPOWER ENGINEERING: CORRECTION MEANS END OF POWER CRISIS. (concise water meters to apply to ) If we make correction of the mistake there has been on hydropower engineering we wouldn't need any other sources of power at all. The cleanliest power will be available by cheapest possible way we can think of. Please avoid the most dangerous power source.) At present we are tapping only minimum hydropower by applying the principle of still water column that it exerts highest pressure at the bottom, so we run only one turbine at the bottom of the running water column. The property applies in standing still water column only. It is a blunder in hydropower engineering. In hydropower we have the running water condition. The pressure effect in a running water column is uniform throughout, from intake to discharge points. Considering the properties of uniformly running water column, it is possible to uniformly run many turbines in series along a single uniform penstock pipe. It will require improvement in the compartment of runner so that water passes through uniform passage as water runs before and after the turbine. THE CRUX - We have to keep water running consistently to maintain constant rotation of the turbines. The flowing water is the main requirement to tap power. Uniformly running water column has uniform velocity and pressure throughout, from intake to the discharge points (Bernoulli Theory). So we can install turbines at any position of the running water column. And, by maintaining uniformity of the water column before, through and after the installed turbine, the velocity of the water column can be maintained constant. Consideration of the property of running water column will open the technology of running turbines uniformly in series without decreasing their efficiency. Because there is no difference in the flow of water even after installing turbines, it remains constant. By running turbines; water or turbines or any other factors don't offer resistance significantly. Flow of water offers no resistance; it is the slickest substance (GBWR). Modern turbines offer little resistance because it is highly efficient, 'Mechanical Advantage' is over 97% and anyway, the turbines rotate with the same velocity as flowing water. We need to develop engineering to make turbines for installing by series principle. The present practice of making turbines is for installing only one at the bottom of a running water column. We can make turbines according to our need. Turbines rotate with the same velocity as running water column. So there is no change in the velocity and discharge rate of water after running a turbine(s). Therefore the turbines don't decrease the power of running water. So we can install as many turbines in series along a single uniform penstock pipe as space allows. In other words, uniformly flowing water can uniformly run turbines in series. (Series is a technical term in science, engineers are mistaken for cascading system. They think both are same. At present hydropower installation is also by cascading method not in series principle). Application of the properties of uniformly running water column can open the door for unlimited hydropower theoretically. Only limitation is the space required for placing turbines. This method not only can end the power crisis but will also help to reverse the present climate change as the power will be available to pump water from rivers as much as we need to keep the land surface always moist, recharge ground water, boost rain cycle and eventually reduce sea level rise. So we must consider the principle of running water column for installing turbines. Applying the property of standing still water column to a running water condition has been a blunder in hydropower engineering. Considering the fluid properties of water (pressure is exerted equally in all direction) and the nature of gravitational force (at a given point never reduced nor blocked nor shifted) multiple turbines can be installed in series along only one water running pipe. The turbines don’t decrease the power of running water, because the turbine rotates with the same velocity as the running water. DEMONSTRATION Water meter is a good example of miniature turbine. Many water meters can be connected along the same UNIFORM water supplying pipe in series and run all of them uniformly. (included in my blog) THUS IT IS POSSIBLE TO HARNESS many folds more hydropower than done by present practice, theoretically unlimited. Engineering works has to be developed differently so that the running water column is uniform before the turbine, inside the turbine and after the turbine. Hydro power can be installed without reservoir / by runoff type, but making lakes as much as possible will hold water in and on land - will be eco friendly, cool climate, aquatic life, lower sea level rise, water sports, transports, greenery, enhance rain cycle, make water easily available in the nooks and corners etc. From the reservoirs we can install turbines as run off type water supply. NAMING 'HYDROPOWER' IS ITSELF WRONG. IT IS NOT POWERED BY HYDRO BUT 'G'. WATER IS USED AS A TOOL TO CAPTURE 'G' FORCE. SO IT SHOULD BE ADDRESSED G-POWERED ELECTRICITY. ANOTHER FLUID IF THERE WERE AVAILABLE ABUNDANTLY COULD ALSO BE USED INSTEAD OF WATER. PE is restored by the heat of the SUN (thus solar powered) as rain cycle and that PE energy is made usable by the force of Gravity. news.yahoo.com/germany-em...14-081559937--sector.html Poster Comment: Should be able to check this"theory" out in the lab or mini-hydro project. Thinking that each downstream turbine will get less energy than the one before. Post Comment Private Reply Ignore Thread Top • Page Up • Full Thread • Page Down • Bottom/Latest

Sounds great and I really hope it works, but aren't dams causing numerous rivers to stop flowing and other major problems? An old liberal bumper sticker used to say simply "DAMS SUCK". Sometimes it appears this may have been more environmentalist than wacko. Just asking. Can you tell I'm no scientist?
Ha Ha Ha Ha HA!

Somebody should tell the East Texas Electric Cooperative engineers about this breakthrough that allows you extract energy from water without reducing the water's potential energy. Then they could build a 1500 gigawatt power plant instead of a little old 24 megawatt plant.
lol - I'm not an engineer, but I don't see how it's possible to extract energy without reducing the PE downstream; to me, it's just counter-intuitive. But I could be wrong. “The most dangerous man to any government is the man who is able to think things out... without regard to the prevailing superstitions and taboos.

I didn't go through all the poster comments to see if an engineer or physicist challenged the concept. Friction alone would reduce strength of flow through the last turbines. But maybe size and depth of reservoir over ride small losses. Each turbine would need a bypass flow "valve" to accommodate turbine maintenance.
My sarcasm in #4 was intended not just to challenge the concept, but to ridicule it as it richly deserves to be. As an aside, there would be no shortage of water or energy in this country if 40+ million illegals weren't here helping to deplete our resources.
Hold it. Hold the phone! Are you suggesting this country go back to dealing with CAUSES instead of just monkeying endlessly with symptoms?
Yeah. But the last 400 or so times that I checked, the only suggestion boxes that fedgov had out were in Tel Aviv and a few Fortune 500 boardrooms.
Righteau........... I take it there aren't any comments on my #1 above? Last call.
Once dam-reservoir is filled then river flow will resume, at a slower rate because of evaporation and larger storage area but the purpose of a dam is to concentrate river flow/pressure into turbines to generate power, so the dam assures continual, more even flow, minimizing flood damage.
