I would
like nuclear fusion to become a practical power source.
As much as harnessing new energy sources
like nuclear fusion, it is solving this basic storage problem that could revolutionize our faltering energy supply systems.
Not exact matches
For less massive stars
like the Sun the process that brings them into existence is quite well understood — as clouds of gas are pulled together under gravity, density and temperature increase, and
nuclear fusion begins)-- but for the most massive stars buried in regions
like RCW 106 this explanation does not seem to be fully adequate.
Carbon, oxygen, iron, and the
like had to wait for stars — especially the massive ones — to form and create heavier elements via
nuclear fusion.
«We will almost certainly learn things
like how to achieve useful
nuclear fusion.»
Nuclear fusion seems
like the perfect solution, with virtually limitless supplies of fuel, no greenhouse gases, and little radioactive waste.
True star travel will probably require technologies
like antimatter or
nuclear fusion rockets, which are currently not much more than dreams.
In lower - mass stars
like the Sun, however, there is insufficient mass to squeeze the core to the temperatures needed for this chain of
fusion processes to proceed, and eventually the outermost layers extend so far from the source of
nuclear burning that they cool to a few thousand kelvins.
While using
nuclear fusion to power homes and businesses may still be some way off, the work proves that the burning of star -
like fuel can be achieved and contained using the current approach.
As was argued here, this
fusion of environmentalism and advocacy of
nuclear power looks less
like a Damascene conversion, and more
like a Reformation.
Deep in the psyche of these over 50s men, other than those
like me who have resisted the
nuclear siren's call, there is a non-rational belief in the endless safe power of
nuclear fission and delusions of
fusion.
Green options
like solar, wind, geothermal; Advanced
nuclear options
like fusion.
But I sincerely hope it does cross them — or, against all the odds and the known physics, we can develop
nuclear fusion power — because, being a cautious (and precautious) chap, I
like insurance.
