The future methods of generating electricity?

[Miyz]

Two main methods of generating electricity that I know off, and that are common:
1 ) Magnets & Coils
2 ) Solar cells.

The only two methods! What do you all think are the possibile future methods?
Are we close? Is there something you recommend me of look at?
I was just thinking of how limited we are in generating electricity, and wondering when the day comes where we are not!

So what do you all think?!

Miyz,

Miyz,

Did you forget the Chemical Method (batteries)?

 

[Miyz]

Did you forget the Chemical Method (batteries)?

Ow yes! Totally slipped my mind.
But other than that! What do you think is possibile in the future? Or what are some project/ideas/theories are being worked at now?

 

[sophiecentaur]

On a very small sscale, you have piezoelectric and triboelectric generation - but don't imagine you could run your car on them!
The other one would be magnetohydrodynamics which, given a massive source of high energy ions, could be 'a goer'.
Wiki can help you with all three.

The other chemical method: fuel cells.

And thermoelectrics.

How about Hamster Wheels, too?

 

[SteamKing]

No. Hamster wheels are prime movers, unless you have electrified hamsters running inside a magnetic cage.

I'd have the RSPCA down on me like a ton of bricks.

AVE Where an artificial tornado is created with generators at the in let ports just google Atmospheric Vortex Engine

There is also cold fusion

 

[ModusPwnd]

There is also cold fusion

Fusion alone, cold or not, doesn't generate electricity. If you want electricity from fusion you need magnets and conductors, like always.

Magnetohydrodynamics? You could get yourself a plasma easily enough with fusion - but then I suppose the fusion wouldn't be 'cold'.

 

[ModusPwnd]

Maybe. I might just think of that as an exotic form of magnetic fields and conductors though.

 

[unclebob]

Thanks for the info. ModusPwnd your right unless you can capture free electrons. maybe? I guess not as conductiors are still needed. again thanks

In fusion, it should be possible to get the hot helium atoms to flow against a voltage gradient and run into an electrode. The electrons would be steered toward another electrode. This would convert helium kinetic energy into DC electricity fairly directly. You wouldn't need turbines and a heat exchanger.

 

[Miyz]

Ow very very interesting methods!

 

[Miyz]

Yet, do you all think the magnet + conductor method will be replaced? I mean something else would be more useful and sufficient?

The future always has promising innovation, but I personally believe this method will stick with us for a very long time.

Thanks guy for all of your responses it has been very enlightening. uncle bob

 

[mrspeedybob]

I haven't seen thermocouples mentioned.

Yep. You've got it about right, I think. Unless we ever have a surfeit of lemons with zinc and carbon rods.

Piezoelectric strips on car tires, rather than in roads?

 

[sophiecentaur]

If it reduces your mpg (which it would have to, to produce appreciable amounts of energy), would there be any point?

 

[TheDemx27]

So true. It would probably waste more energy than create it as well. Another kind of perpetual motion machine baloney. Thanks for confirming.

 

[sophiecentaur]

It made me think of those flashing trainers that kids wear - but I believe they have batteries in them - what a waste. It would wear the little darlings out quicker if they actually needed to supply the energy from their own muscles.

 

[Crazymechanic]

Some of you mentioned the fusion and magnetohydrodynamics things here , well I personally think it could be a good thing if only we could learn to achieve the first thing the fusion itself and sustain it for considerable amounts of time.
When the hot ions would pass through coils that would generate electricity also the method about the helium atoms and DC which was mentioned here sounds interesting although haven't read on that one.
Because on the current technology we are actually wasting a lot of energy that we just can't get like an average RBMK or other nuclear fission reactor is rated at maximum thermal power of about 3000MW of which only about 1000mw is the maximum electricity produced I think mainly due to the water/steam/turbine 30/40% efficiency level.
I think with the MHD that generates electricity directly from the plasma charge we could get better efficiency ratings.

 

[Thermolelctric]

Various resonant systems seem very promising for small scale electricity generation from heat difference.
Thermoacoustic heat engines for example.

[dbmorpher]

Well there is really only a few major types of energy
Mechanical, Electric, Electromagnetic, Magnetic, Nuclear, and Thermal
There will be a limited number of conversions because there is a limited number of energies.
