Mini-nuke reactor?

I confess, even a hard-bitten nuclear skeptic like myself is intrigued by this idea. Though I don't know remotely enough about it to offer an informed opinion, the potential applications in the north of Canada are tantalizing -- though given how lightly populated the north is, even this mini-reactor might be too large:

The portable nuclear reactor is the size of a hot tub. It’s shaped like a sake cup, filled with a uranium hydride core and surrounded by a hydrogen atmosphere. Encase it in concrete, truck it to a site, bury it underground, hook it up to a steam turbine and, voila, one would generate enough electricity to power a 25,000-home community for at least five years....

There's (a bit, not much) more at the company's website.
