A plasma at 100,000,000oC
Fusion will be the energy of
the future. It is the process that drives the stars along with our sun.
In the long term this will probably be the only practical mass market energy
with an acceptable low impact on the earths ecology.
Solar, wind and wave power may have a more ecological acceptance, but these
alone can never meet the mass world requirements.
There are many engineering and physic issues to be resolved
before controlled fusion power will become a reality, but it is a
