How do I store energy

[Anderson]

Hi all,

I am thinking to save the output power from 115V AC 3 phase generator and 28 V DC generator while testing.
Every day we will be testing the above generators for more than 3 hrs. I would like to get any idea of how to save the output power and use any thing useful out of it

Any suggestion or ideaS?
thanks

Batteries are the usual way to store electrical energy.

Why don't you tell us all the details. Then we may be able to give a more specific answer.

To start with, what are the power ratings of the generators?

Or, to get more creative,

Lift some large weights.
Pump water up hill.
Spin up a large flywheel.
Charge a huge bank of capacitors.
But my favorite is compressing air:

You forgotten magnetic storage (if you have access to billion dollar fabrication facilities): http://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage

And heat energy storage: http://en.wikipedia.org/wiki/Thermal_energy_storage

Most people are under budgeted.

Cool! or Hot! take you pick.

Heck, buy a high-wattage amplifier and listen to beautiful music while you test.
If you've got power to spare, get some disco-mirror balls and some go-go dancers to listen to the music with you.
Otherwise, KrisBlue NZ's battery idea would be my second choice.

What if the batteries are already fully charged?
Lift some large weights does it for me.
Have plenty on hand so you do not end up with the battery problem above.
Weights are cheap from local ironmunger.

Connect to the grid and sell your excess power to the utility. Cash, depending on bill denomination, can be very high-density energy storage.

Supply authorities are doing their utmost to discourage this in Aus.
Their gear is designed for outgoing and since they have very little control over all this outsider grid connected equipment, it's causing them quite a few headaches.
Seems the pollies never bothered to talk to the supply guys before they opened their gobs and promised the world.
Bit the same as the "insulation" headache.

Personally, I prefer lifting weights. It's not efficient, but kinetic energy seems to work in most situations. You can also add more weights at the top of the stroke.
