That was my immediate thought too. Hook it to a super capacitor. The only problem is the self discharge is probably higher than what the nuclear cell can feed.
That's a good point; it becomes less economical if you need multiple of these cells just to counteract the self-discharge. Even so, it's really just a demo of the technology; they do mention they expect to have a 1 watt model later this year.
