assuming i could get hold of the capacitors to make this work:
in the uk we have 230vrms 50hz ac power so running 20 220w tecs on rectified and smoothed mains each would have 11.5v and draw about 19amps so in total the system would be 230v 19a
230x19= 4370 or 4.370 Kw or 4.370 units of electricty per hour so 38281.2 units per year @ 5.45p per unit. total cost £2086 per year or $3000. but for that you would have 2600w of cooilng which, if used with 2 tecs on the cpu and the rest on the water chiller, should keep the cpu well below zero.

bit expensive compared to phase change though.
