I've extracted some figures from an industry publication
and arrive at a worldwide electricity generation capacity
of 1.6 TW.  Assuming that 1% of that power is smuggled into
the deep space cracker we're not even close to 33 minutes,
and it doesn't matter whether we're looking at a one-off
every so often rather than a continuous 40 a day.

And that's still on optimistic assumptions including

1)  testing keys for free

2a) running on earth at 3 K rather than 300 K

or

2b) no bother transmitting power & signals into space
    (Like if the cracker had been secretly installed on Voyager 2
    that'd be your 33 mins gone waiting for the radio.)

IBM have published a communications scheme that claims to recover
energy normally lost - it was on their website a few months ago.
I skipped reading it at the time because it sounded dotty.
