How will we travel to the stars in the future?
There are a lot of exotic theories floating around for future star travel: ion drive (slow, but reliable); solar sails; laser propulsion; nuclear fusion drives. None of these are phony “Star Trek” warp drives (doesn’t make ANY scientific sense–they’d be crushed to death!), but which one is the most feasible?

fusion in fission reactor?
why doesn’t fusion reaction occur in reactors using heavy water as coolant? I do not mean chain reaction. Even a few instances. As for as I know, energy of the liberated neutrons is about 1 MeV, while fusion of deuteron requires about 5GeV. But if it is so, than how they create fusion in bombs. […]

How much energy could be generated by adding solar panels to the Alaskan Pipeline?
Using low-end, i.e. cheap, solar panels, based on existing technology, how much energy can be generated by adding solar panels to the total length of the Alaskan Pipeline? And if possible, how does that compare with the energy of the oil being pumped through the pipe. Not sure what the light cycle is along the […]
Is nuclear energy a reasonable alternative to fossil fuels?
Nuclear energy is clean. It has caused 0 deaths in the United States. It outputs 2.7 million times more energy than coal. All we have to figure out is what to do with the waste. What’s your opinion on nuclear energy?

How does a simple cell work and is it actually a galvanic cell or a electrolytic cell?
There are 2 different electrodes, right? One’s an anode and one’s a cathode. And apparently, a negative electrode is called an anode. Since it’s negative, shouldn’t it attract *positive ions* so reduction will take place? Why does oxidation take place instead?
How do I conserve electricity on 20 computers?
is there a way? like plugging my computers into a car-battery and use an AC-DC converter? then the battery will be re-charged using an AC-DC converter?

what are some good sources for information on Nikola Tesla’s inventions and life?
I have a report to do, and I have source cards due friday. The encyclopedia had about a paragraph that was very unhelpful.
is the electricity generated from wind turbines dependent on wind speed and swept area alone?
or is it that the faster the rpm, the more the production. (of course this in itself is dependent on the above two criteria) what i need to know is whether a alternator produces same energy at 100 rpm and 300 rpm. also what are the factors that decide how much energy a alternator produces.
Where is all of the rumored oil?
I always hear liberals talking about these oil conspiracies and claiming that we’re doing all of this random stuff for oil… If these conspiracies are true, where is all the oil?

What is the maximum useful work which can be obtained from a hydrogen-oxygen fuel cell that produces 1.67 kg of water at 25°C? (Assume 1 atm pressure for the gases.)
How is electrical or chemical energyconverted into hydroelectric energy?
If you know that please help me with. Thanks a lot guys
introduction to NUCLEAR FUSION as a new source of energy 1/2
im working on this video for quite some time now, and i finally finished it :) the recent videos about the free energy conspiracy-theory more or less set the stage. nuclear fusion is quite real, watch the following clip: uk.youtube.com wikipedia is great when it comes to nuclear fusion, check out the articles about: nuclear […]
