The standard joke about nuclear fusion is that it's the energy technology of the future, and always will be. Well, fusion is still an energy option for the future rather than the present, but small steps forward are being reported on several fronts. That even includes the long-ridiculed campaign for "cold fusion."
Efforts by the Italian-based Leonardo Corp. to harness low-energy nuclear reactions (the technology formerly known as cold fusion) have reawakened the dream of somehow producing surplus heat through unorthodox chemistry. Today, Pure Energy Systems News reported that Leonardo's Andrea Rossi signed an agreement with Texas-based National Instruments to build instrumentation for E-Cat cold-fusion reactors.
Will this venture actually pan out? The E-Cat reactors are so shrouded in secrecy and murky claims that it's hard to do a reality check, but most outside experts say that the concept just won't work.
Some observers are similarly pessimistic about the other avenues for fusion research. The basic physics of the reaction is well-accepted, of course. You can see the power generated when hydrogen atoms fuse into helium when you look at that big ball of gas in the sky, 93 million miles away, or when you watch footage of an H-bomb blast.
But no one has been able to achieve a self-sustaining, energy-producing fusion reaction in a controlled setting on Earth, even after more than a half-century of trying.
