We have
generated small amounts of electricity just by getting the fabric damp — without the need for any additional circuits or components.
Not exact matches
However, when a substantial number
of turbines are installed over a
small area, the
amount of electricity generated is no longer governed by simple multiplication, according to the researchers.
One
of the problems with previous methods was that the
amount of energy produced in, for example, a system using salty and less salty water to
generate electricity, was too
small relative to the
amount of water used.
Wind turbines
generate small amounts of expensive, unreliable
electricity from gargantuan installations on thousands
of acres.
And as I've mentioned before, even a
small amount of solar penetration pushes down
electricity prices, which hurts the economics
of baseload
generating capacity.
