If you want to see what I consider to be "imaginary" power source

will publish any press release about some new fuel cell, unicorn breath,
unobtanium or imaginarium battery that is just about to change
everything and make us ready to abolish the IGC.

I know exactly what you mean.

A year or three ago "New Scientist" would give 1/4 - 1/2 page to any test-
tube scale, proof-of-concept experiment for a new battery technology that
was going to change the world. Without exception these were never
mentioned again.

Thankfully, they've stopped doing that, and for good reason: the
theoretical capacity of say, Lithium-based batteries, was determined
decades ago and once cells were designed with capacities that were
reasonably close to the theoretical maximum, subsequent development has
been concerned with maximising charge/discharge rates, battery life,
operating safety, cost and weight. In short: we already know what energy
storage capacity is achievable with any practical cell chemistry and
further research isn't going to produce new, currently unknown super
capacity batteries.
