I see one mistake in the calculations above.
The number of reactions you would get is
# reactions = rate * vol * t = <ov> * n1 * n2 * vol * t
The total ions in the fuel is
total ions = (n1 + n2) * vol
Therefore, the fraction burned is
f = # reactions / total ions = <ov> * n1 * n2 * t /...
I recently came upon a reference to http://www.focusfusion.org, which led me to discover http://www.prometheus2.net and http://www.electronpowersystems.com. What these companies have in common is they propose to generate power using "clean" proton-boron fusion in a pulsed reactor. By pulsed, I...
