Power station
A power station or power
plant is a facility for the
generation of electric
power. At the centre of
nearly all power stations is
a generator, a rotating
machine that converts
mechanical energy into

Renewable energy
Renewable energy (sources)
or RES capture their energy
from existing flows of
energy, from on-going
natural processes, such as
sunshine, wind, flowing
water, biological processes,
and geothermal heat flows.

Liquid nitrogen economy
A liquid nitrogen economy is
a hypothetical proposal for
a future economy in which
the primary form of energy
storage and transport is
liquid nitrogen. It is
proposed as an alternative

Fuel cell
A fuel cell is an
electrochemical device
similar to a battery, but
differing from the latter in
that it is designed for
continuous replenishment of
the reactants consumed; i.e.
it produces electricity from
