[ausev] Ultracaps

[Roy Holder]

I think because the calculations of the ultracaps were off by a few decimals.
maxwell rates their BMOD0063-P125 125v 63F at only 101.7 watt hour

http://www.maxwell.com/ultracapacitors/products/modules/bmod0063-125v.asp

that makes the earlier calculations of the 15v 50f at 5.6 kwh not correct.

Lessee now, 1/2 C V^2 = 0.5 * 50 * (15)^2 = 25 * 225 = 5,625 watt-
hours = 5.6 kwh (Right?)

nope, 
Energy Available equals 1/2C (Vnom^2 – 1/2Vnom^2) /3600

= 0.5 * 50 * [225  - 56.25]/3600 = 1.2 watt hours

much less than above.
