Fascinating story but one should be careful about not properly assessing the
challenges of this technology/concept. The idea of "distributed energy" is
nothing new. For years - mostly in California - many high tech companies
have been working on developing a devise that would generate electricity in
your own backyard or basement.

The huge costs are not on the fuel cell - which they are but as the article
shows can come down - the real problem is in managing a stable electric
system when millions of households become "power producers". Remember
electricity cannot be stored, so supply and demand must meet
"instantly"...That's the complex jobs of the "balancing pools" through a
complex process of auctioning and entry rights in deregulated markets such
as Alberta or Colombia. In controlled markets, the regulator decides which
sources to use. Generally speaking the first source to go is the cheapest
one (hydro, coal, fuel, natural gas) and the one with the highest level of
reliability. Less reliable sources (wind, solar) enter after to supply "peak

The costs on information technology to manage such level of complexity (each
house generating its own power) should not be ignored...
