Power Felt Converts Heat to Power

I wish that such development was given priority over less important things such as Facebook for example. We desperately need to move on from using old tech that is expensive and extremely limiting. Fossil fuels is so twentieth century, higher density sources of energy are needed and efficient use of energy needs be prioritized so that costs can go down.

Here's what many investors will ask:

Will it generate quick profits with minimal risks and investments, or at least big enough profits to be gambled with?

Alternative energy requires big investment, and lacks the quick/large profits for many investors.

Things like this is what generates projects like Facebook. Technology generates tools to be used by business minded people to generate capitol which creates jobs. Where do you think researchers get the funding?

Science and technology is the wheel for prosperity.

Matrix was way ahead of its time anyways :D

Yeah, I had the same flashback to that cinematic with Laurence Fishburne describing the humans/BTUs and the copper-top.

Why not use the heat produce from CPU/GPU/LCD in a phone itself to charge the phone while we are using it. Those heat combined probably are hotter than my palm.

I've always wondered why they don't use sterling engines on the part of a car's exhaust where it connects to the engine. It get's red hot there and could probably power one or even two small sterling engines to provide more power to the electric engine if it is a hybrid.

140 nanowatts......

Does anyone here know how inconceivably small that is? You would need 7 of these stacks to make a milliwatt (980nW), and 7000 to make 1 watt. Let's put that in terms you might understand, to light an 11w CFL bulb (which is your standard 100W equivalent in old light bulbs) you need 77,000 stacks of these devices, (and all placed at the optimal heat differential).

How much energy does it cost to produce and what is its lifetime? What is the optimal heat differential? Everyone does realise that the matrix is fiction yeah?

Honestly, I thought more people that "knew science" would read this as opposed to what a lot of the other commenters clearly are... (stupidheads).

Excuse me while I go enjoy my time on facebook talking to my friends for less energy spent than in the olden days where I would have to mail everyone I knew around the world to keep in touch, or phone for an ENORMOUS phone bill. Yeah, lets plough money into this research. It is totally just what the world needs.....(idiots)

Human will be use as batteries...they'll be store in goey liquid to preserve them and put in constant state of sleep and dreaming in order to prevent them to wake up and keeps charging the fuel reactor....

Welcome to the MATRIX.

so you see no potential for this to get better and become a more viable solution?[citation][nom]memadmax[/nom]For the guy that wants alternative energy: Fusion and nuclear power....Wind chimes and mirrors are not gonna cut it.......[/citation]

honestly, with solar power, you can generate a crap ton of energy in places that are borderline useless for anything else (the desert)

wind is basicly useless when you know how little each turbine makes.

im willing to risk meltdowns for cheaper power, and more advancements, but people refuse to let nuclear advance at all because of Chernobyl and 3 mile island (which they cant prove ever leaked anything) and more recently japan.

A regular engine already takes advantage of temperature differentials. The greater the temperature difference between the combustion chamber and the heat sink (the cylinder walls), the higher the engine's efficiency. Most of the heat energy you could capture with a stirling engine can already be captured with a regular engine simply by making the cooling system more effective.

If you replaced the cooling system a small stirling engine, yes it'll generate energy, but the less effective cooling means the engine loses efficiency. You're basically shifting energy generation from the ICE to the stirling engine, not generating additional energy from the heat differential. For there to be net additional power generation, you need a really large stirling engine which can handle the large amount of heat flow normally handled by the cooling system. And when it gets that large, the additional energy you burn carrying the extra weight around usually consumes more energy than it generates.

Stirling engines typically weigh a lot more per Watt (or hp) than an internal combustion engine. For transportation applications, that means you're almost always better off using a bigger ICE rather than tacking on a stirling engine. The story changes for fixed static operations. There, stirling engines can be useful if you can bear the initial investment and additional maintenance costs (again, typically a stirling engine produces fewer Watts per $, so the temptation is simply to use your money to buy a bigger ICE). Note that steam engines and the steam turbines used in nuclear power plants are essentially heat engines, like a stirling engine. That is, they derive all their mechanical energy from heat differentials, rather than from expansion of combustive gases.

Or you could just give scientists the means to complete the research on thorium Liquid fluoride reactors. Just sayin'.
