I have a class called "alternative energy" and chose Superconducting Magnetic Energy Storage (SMES) as my project. I have research and what not done but he asked me make up (or at least write down) an example how to calculate the energy stored

below is link to wikipedia on the topic including the formulas i use in report:

http://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage


can anyone come up with a problem that can be used as a good example in a report or presentation, please???

 

anyone?

 

Some ideas:

1) What are we going to do when we run out of helium? (e.g., how is helium produced, where are the wells that produce it, how much is there?) Maybe we can trade helium for oil someday.
2) As described in the Wikipedia article:

Although the high-temperature superconductor (HTSC) has higher critical temperature, flux lattice melting takes place in moderate magnetic fields around a temperature lower than this critical temperature.

That is, problems with HT superconductors.

my mistake i didnt write my thing correctly, what i meant to say was i need a practice problem done out to show how to calculate the energy stored.
(but i did use the last comment on my report thanx "jpanhalt")

 

A neighborhood micro-hydro plant puts out X watts. The neighborhood consumes Y watt-hours per time-frame. How big does the storage unit need to be?

 

Hi corner boy,

Magnetic Energy (produced or stored)= (1/2) * L * (I^2).

where I = current in the coil
L = Inductance of the coil.
Will this be helpful?
