bumab Posted February 5, 2005 Report Share Posted February 5, 2005 The teather idea. It's been tested with the international Space Station. Yeah, and it worked! They were just unprepared for the current. Seems like a good way to tap that magnetic field thing to me. I wonder if there's any plans in the works for more tether research?

TeleMad Posted February 5, 2005 Report Share Posted February 5, 2005 and the only powersource that was never alive is nuclear... What about electricity produced by hydroelectric power plants? What about water wave energy? (Some scientists have designed systems that obtain energy from the undulating motion of water waves). What about frictional energy, as is used by some hybrid cars during braking to help recharge the battery? What about thermal energy, such as is used in Iceland, I believe, by tapping into the natural "volcanic" activity? What about a typical battery?

alxian Posted February 5, 2005 Report Share Posted February 5, 2005 i said hydro.. *frowns i don't mean to sound like a know it all but i'm very well aware of most of the power methods used by humans the best application for geothermal/hydrothermal power (besides getting women to strip down in a resort in the winter time because the water comming out of the plant is still warm.. joinging the water and power system (steam would make more potable water.. such systems help their communities by being cheap (after substantial investment) and allow them to grow faster than they otherwise would, relieving them of the stress of sourcing power and water etc from neighbors, they instead export it generating wealth.. quite a triple threat and well worth that investment) is that written about by clarke (venus prime, i think, don't quote me)(sourcing power from the differential of temparatures of the cold depths of the ocean and the solar heated surface, but stupid human politics keeps this massive potential energy source from being tapped.. politics.. if only governments could do things for the better of the people without having to deal with established industries and corporations etc. they can't of course, or we would have achieved free power and utopia back in the 50s and 60s, at the expense f all the research and growth we've accomplished instead.

pgrmdave Posted February 5, 2005 Report Share Posted February 5, 2005 Would the teather idea generate enough electricity to surpass the energy expended to put the satellite up and keep it up? Link to comment Share on other sites More sharing options...
bumab Posted February 5, 2005 Report Share Posted February 5, 2005 I believe so, using an ellipical orbit plan. It generates power (thus producing drag) near the low point (apoge? something like that?) and get's flung out on a more circular orbit for the next round. This is a really basic link, I can't find the origional one I saw... http://www.space.com/businesstechnology/technology/space_tether_020306-1.html As for keeping the satalite up there, a current passed through the tether provides thrust from the magnetic field repulsion whenever the satalite gets too low. It would be an off-on power supply, I imagine. Link to comment Share on other sites More sharing options...
alxian Posted February 5, 2005 Report Share Posted February 5, 2005 batteries like nuclear power are two of the few energy sources that derive power from the state change of non organic matter.. i.e. not directly attributed to the sun. can anyone name other energy source based on elements compounds energy fields not in some way linked to the sun? i knwo there have to be more but as i said dc and nuclear are some of the few i have others. mettalic hydrogen (which is conductive) can be use for extremely high yeild fuelc ells not only trough the regular function of electrical potential of creating water vapor but by the possibly explosive sublimation phase change from solid metal to gas. also tossing satelites into orbit that source power from earths magnetic field not to mention the raw power of the solar wind falling into that magnetic field... consider it a waterfall of planetary proportions. and the possible sourcing of power directly from strings by creatnig domains within which all string vibrate in unison allowing amplification (with that extra power bring sucked off). this will of course modify the local space and the particles created by messing with the strings may or may not be interesting in and of themselves.. alchemists reborn <scientists who are able to modify the atom and everything greater, from within Link to comment Share on other sites More sharing options...
alxian Posted February 5, 2005 Report Share Posted February 5, 2005 Quote:Originally Posted by alxiani said hydro You also said: Quote:Originally Posted by alxianand the only powersource that was never alive is nuclear... So are you saying that water is alive? -------------------------------------------whoa.. this honestly took me a minute i said and.. in the second sentence hydro power= solar energy, in addition to nuclear power and chemical phase change power other than nuclear (batteries) unlike fossil fuels don't involve matter that has been alive.. technically this is not entirely correct since the chemicals themselves could have passed through a living creature as simple as bacteria (who at one point was life defacto besides seaborn life like algae.. taking that into account batteries and the chemicals within could be traced back to bacteria and thus indirectly the sun.. -------------------------------------------and.. OHHHHH a tether??? ok, i was like theater?? emotional energy?? tether power is .. meh .. merely so~so.. sourcing power from ions is fun but the flow of charged particles requires something more substantial like huge meshes that suck up power and beam it down to earth.. lasers? or microwaves? either way they'd create massive no fly zones. i'd thought the space elevator best solved that problem, they send the microwaves to a station atop the elevator, the elevator would have superconducors at its core and at te base of the elevator some way of passing the power to earth (microwave again but much less leathal to birds and commercial flight paths (like skycar networks??? ;) ) Link to comment Share on other sites More sharing options...

In other words, don't expect you to admit that your statement, "and the only powersource that was never alive is nuclear..." was wrong. Okay, I get it now.

alxian Posted February 5, 2005 Report Share Posted February 5, 2005 no. nuclear particles may never have been part of a living being (born on earth) they are born by the creation of the planet (and some longer lived isotopes from even before then) i'll recant in light of the second post that yes water isn't alive but its constituants are, and no other system on earth has passed through living creature more than the water system..... since hydro power is sourced from water as is and not pure dihydrous oxide then yes water counts as a probably once living resource thus linked to the sun of course i will apologize for not properly explaining my own example.. which i myself was slightly less than technical in backing it up.. ;) but i'm foriven so its ok.

fusion Posted February 6, 2005 Report Share Posted February 6, 2005 What are strings affected by since alxian was talking about harmonizing strings for obtaining energy from the vibrating strings? Theoreyicly how could strings be harmonized as they make up everything that could be used to harmonize them?? ;) Link to comment Share on other sites More sharing options...
alxian Posted February 8, 2005 Report Share Posted February 8, 2005 theoritecally impossible for now. unless you've managed to harness super potential particles (tachyons) which are thought to impart energy to strings and become tardyons thereafter(???)

Qfwfq Posted February 24, 2005 Report Share Posted February 24, 2005 no. nuclear particles may never have been part of a living being (born on earth) they are born by the creation of the planet (and some longer lived isotopes from even before then)How about carbon 14? They are born from nuclear reactions (mostly in the sun) or they are part of the chain of ensuing decays. water isn't alive but its constituants are, and no other system on earth has passed through living creature more than the water system..... since hydro power is sourced from water as is and not pure dihydrous oxide then yes water counts as a probably once living resource thus linked to the sunMuch more straightforward: how did the water reach the higher ground, before flowing downstream?

Fishteacher73 Posted March 9, 2005 Report Share Posted March 9, 2005 Everything can be linked to the sun. All the atoms were at one point part of the sun, or derrived from other atoms that were, even the radioactive ones. So inherrently every form of ebnergy is essentially solar with that argument. Barring the "creationist" view of solar based energy, the only other form of energy that is not derrived as such would be geothermal or nuclear. (Perhaps one could argue tidal action as a source but that is gravitational which again stems from the sun). Link to comment Share on other sites More sharing options...
Qfwfq Posted March 10, 2005 Report Share Posted March 10, 2005 it wasn't.What wasn't? & wasn't what? My question was: "how did the water reach the higher ground?". It must, before it can flow back downwards. Anyway, in short, what Fishteacher says is right. Even geothermal is somewhat touch'n'go. Link to comment Share on other sites More sharing options...
