- Several postings ago, I mentioned the possibility of quark-catalyzed fusion.
- As promised (and requested) here are some additional details...
-
- I smilied [:)] my original reference to quark catalyzed fusion since it
- doesn't really apply to the problem of catalyzing fusion in a ramscoop :(
- but it remains an interesting possibility for power generation here on earth
- *if* free quarks can ever be isolated.
-
- Quark catalyzed fusion is similar in concept to muon catalyzed fusion
- with a difference - quarks don't decay.
-
- From F. Close, ``The quark structure of matter,'' in The New Physics,
- P. Davies, Ed., Cambridge: Cambridge Univ. Press, 1989, p. 422:
-
- "Some of the practical details have already been evaluated and are as follows:
-
- "A pair of antiquarks with charge -4/3 come to rest in hydrogen or deuterium at
- a pressure of 2000 psi (1.4 x 10^7 N/m^2). They capture a molecule and form
- a system with charge -1/3. The resulting `quark-molecule' is very excited.
- It takes a short time to settle down, `de-excite', and in this time it captures
- another nucleus, of charge +1, and fuses. A quark is released to go on and
- do the job again. The process can be summarized by the sequence,
-
- Q + [D(pn) + D(pn)] -> [3H(pnn) + p] + (energy) + Q,
-
- where Q = quark, D = deuteron, and 3H = tritium.
-
- "The new quark moves on to the next nucleus and can initiate further fusion.
- The reaction rate is one per second at 2000 psi pressure. For deuterium,
- this releases 3.65 MeV energy per fusion. A few grams of quarks could
- catalyze fusion and generate 10% of the total USA energy consumption!
-
- "There appears to be only one weak link in the whole enterprise: no one has
- yet found isolated free quarks!"
-
- Various people have found evidence which suggests that free quarks exist
- including Brian McCusker (cloud chamber photo in 1968) and William Fairbank
- at Stanford (a variation on Millikan's experiment using niobium coated
- tungsten balls).
-
- At present, theorists conjecture that quarks are confined in colourless
- clusters (hadrons) but this has not been *proved*. It seems possible that
- free quarks may exist.
-
- If nothing else, it is interesting to contemplate the possible consequences
- of free quarks...
