Suggestion: ZPM

*Insert Obligatory Face-palm*

For what do you want even more storage? 1MEU is more than enough to power an entire workshop for a whole night. If you have multiple MFSUs sitting around fully charged you should get a MassFab.

Its never enough power for me >:D

1 or 2 of T4 machines will drain MFSU's like nobody's buisness. NTM long-distance teleporters. (which really need to use less energy, they're useless, as teleporting someone with a full inv and all armor 600 blocks will cost a full 3kk EU. To travel that in a quantumsuit would take like less than a minute and take only like 10k EU.)

not that i know lots about ZPMs but iv always seen then as a incredably large souce of power, no some thing were power can be stored.

but still good idae.

for higher-tech storing device why not use UU-Matter based storage encased in iridium? (and also use MassFab or some minor modification of it or addition to MFSU like Electrolyzer for (de)charging them) with capacity like 5 mil, but REALLY fast charge/discharge ( 1 mil per 5 sec probly fast enough)
would give UUM and IP new and awesome uses!

Since ZPMs extract vacuum energy shouldn't their capacity be 10^113

I think this would be useful, if purely because it would allow you to make longer lasting *infinite* energy sources for experimentation with TMI, like with the force field mod, where I create like 10 MFSUs, wire em up, and stuff laptrons in them, which dont really last all that long.
