plasma's all around us in the universe, we
live in a relatively cold
environment, so natural plasma is rare on Earth.
Plasmas are often used in industry to make
micro-electronics. Engineers make artificial
plasma to conduct electricity in neon signs
and fluorescent bulbs. Right now, scientists
working on fusion - a cheap energy source for
the future - are experimenting with plasma
in the lab.
Someday, plasma fuel might
power our planet
Scientists work with super-hot plasmas inside
this reactor where temperatures can soar
to 100 million degrees! Research into fusion,
the energy that powers the Sun, may yield
clean fuel for the future.
