    if a nuclear power plant goes down, a whole city is in the dark.

    wind is better. more relaible. eco friendly. and it`s cellular. if one goes down the effects aren`t so dramatic.

    you can slap a windmill up anywhere on the planet. nuclear power plants are harder to build and harder to maintain.

    Gerry: Yes, that is true, but if this works out I imagine there would be so much reserve energy that it wouldn`t really matter.

    Windmills are great, but the problem is that in some areas it isn`t that windy which means no energy. The only viable option for wind energy are those high-altitude ones.

    wind is better. more relaible. eco friendly. and it`s cellular. if one goes down the effects aren`t so dramatic.

    One of the biggest problem with existing wind power technology is that it is *less* reliable. You can`t use it for baseline power and you can`t easily vary it`s output to meet demand. The other really big problem with it is that it can`t produce enough electricity anyway, even if you`re willing and able to cover the country with it. A sparsely populated country might be able to get enough power sometimes by covering vast areas with wind farms, but even then you just can`t run a country on "enough power sometimes".

    The only form of wind power that`s viable on paper is high altitude wind power and that has a bunch of it`s own problems.

    It is not the solution you portray it as being.

    But the solar system is defined as the star Sol (AKA the Sun) and the 8 planets orbiting it. So, by definition, there is only one star in the solar system.

    if a nuclear power plant goes down, a whole city is in the dark.

    Not if you have a comprehensive grid and spare capacity. It might be a problem in some parts of the USA, which is very large and quite sparsely populated in many areas, but it isn`t a universal problem. Power stations are taken offline quite often for various reasons and the system carries on working.

    You have to vary alternative sources to suit location and it`s far harder to try to splice together a reliable system than it is with power stations using something that you have control over. You need to come up with something that allows a lot of overproduction and some form of storing massive amounts of energy long-term or exploit something that`s almost always dependable (e.g. high altitude wind, wave in some areas).

    Eco friendly, yes. Reliable, no. It only generates electricity when the wind is blowing. That`s not reliable. As Angilion says, it`s just unsuitable as a baseline power source. The national power grid is a delicate beast to manage.

    National Power Grids 101:

    AC electricity cannot be stored, which means that the amount generated must be constantly matched to the amount being used, minute by minute, around the clock.
    The system frequency and the demand-supply disparity are inextricably linked. If supply exceeds demand, the frequency rises. If demand exceeds supply, the frequency falls. If the frequency changes too much, the grid collapses and you get blackouts.

    So what you need to run a grid is electricity sources that you KNOW you can control, and that you can turn on and off at will. Wind cannot do that.

    This is how much the power demand in the UK National Grid has varied over the past 24 hours, in MW:



    If you rely on too many unpredictable power sources like wind, you can`t continually match supply to demand.

    Hydro is good for that, because it`s clean, efficient and reliable. We have a (relatively) lot of hydro in Scotland.

    Geo thermal energy is the way to go to replace fossil fuel plants, and is proven to be more reliable by a wide margin than wind, and has a greater return than solar. And is know to have a much smaller "foot print" than hydro electric power.

    It only generates electricity when the wind is blowing.

    It`s even worse than that, as it only generates electricity when the wind is blowing within the right range of speeds. Too much wind will shut the "windmill" turbines down just as effectively as no wind at all. It`s not hurricane levels either - normal wind is quite often too much.

    Wave is looking good here in the UK. Lots of coastline on an island and the waves come all the time day and night quite consistently. The biggest current problem is that wave power is too strong. It quickly breaks the power stations. If that problem is cracked, northwest Scotland alone could in theory power much of Europe. The power is there and devices to convert it efficiently exist.

    AC electricity could be stored in flywheels but there would still be losses due to friction and counter EMF. When you refer to frequency variations do you mean voltage, or potential, variations? I do not own an oscilloscope so I cannot monitor frequency but I would think frequency has to do more with the actual speed of the generator being turned than the demand for wattage. Also, I heard a rumor when I visited Germany last year that some portions of europe where converting over to DC power sources since there is obvious advantages to consistency but modern electronics can solve the problems with transmission.

    Is that anywhere near being viable for storing GW of electricity? Or are we looking at flywheels the size of cities? Countries?

    If you have plenty of space, you could store energy in pairs of artificial lakes. One higher, one lower. Pump water up when you have spare electricity, let it run down through a hydro power station when you need more. It`s not all that efficient, but it does allow what is effectively storage of very large amounts of power.

    meepmaker: like lolboy said, the magnet fields help keep the hydrogen from touching anything, and i assume its all contained within a near vacuum so that there is no heat transfer or resistance when the hydrogen is circulating. Keeping everything safe and efficient

    Here : This website has info about research being done in the US by the NIF. They use a different method with lasers to induce fusion. Supposedly, this fall, NIF is suppose to have there first fusion reaction where they have more energy output than input.

    1.6L V8s do exist. Smaller ones, too. I doubt if you`d find them in a car, though. There are more efficient designs for car engines with that kind of displacement. You get some V8 motorbike engines though and they`re they`re the smaller ones.

    The relatively large engine sizes in the USA are as much cultural as technical.

    @Angilion

    The size of the flywheel necessary would only need to be about the same size as the generator already in use, so double the size of the current facilities. The amount of energy stored is a function of mass and velocity of the flywheel. Your proposal would consume larger areas of land with the lakes idea.

    Couldn`t we just solve all of the world`s energy needs by burning douchebags like the ones on Jersey Shore? Sure, it`s not the cleanest energy source, and it would create a smell like hair gel and old leather, but at least we`d never be in short supply, right?

    AC electricity could be stored in flywheels but there would still be losses due to friction and counter EMF.
    Well, yes, flywheels will work in the kW range. It`s not practical on a national grid, working in GW.

    When you refer to frequency variations do you mean voltage, or potential, variations?
    Um... neither. Frequency is measured in Hertz. I mean that the frequency of the National Grid, which is nominally 50Hz, varies around 50 depending on how well the demand and supply are matched.
    The UK National Grid official frequency tolerance is 50 +- 0.5Hz, but they usually try to keep it to +-0.2Hz.

    I haven`t heard about that plan. I know there are several HVDC lines around in Europe, mainly connecting between countries, but I haven`t heard of any country planning a total conversion. Sounds interesting, but I`m not sure about it. HVDC has its own drawbacks.

All rely on the basis that the energy used to produce the energy is less than the energy produced. I`m fairly certain that would have been something the scientists considered before starting their tests.
