I wonder how much they cost and how efficient they are compared to other ways to produce electricity.

  It's not so much the cost efficacy that makes these attractive, it's the 100 year lifespan.

    > ‘You could embed a tiny nuclear chip with a sensor into concrete, come back a decade later and query the sensor about humidity on certain days,’ says Peter Cabauy, chief executive at City Labs, a Florida-based company developing micronuclear batteries. ‘Put it down. Forget about it. Use when necessary.’ Yeah, I hope those construction workers remember where the nuclear chip is embedded a few decades later, wouldn't want to smash it.

  Not very, at all, because they produce miniscule amounts of power. The main practical point is they keep going for a very long time, well beyond the point where a chemical battery, which might be able to hold more energy, would self-discharge.
