Fusion is hot

Literally.  As written earlier, a pB11 fusion reaction produces 8.7 MeV ( million electron volts) of energy.  This can be represented also by converting to a temperature measurement with this equation below:

Note that a mere 1 electron volt is equivalent to approximately 11, 605 degrees Kelvin.  Now a pB11 reaction above would be multiplied by 8.7 million in order to obtain the heat equivalent of the reaction.  That figures out at 100964 times a million, which is over 100 billion degrees Kelvin.  [between 2 and 3 orders of magnitude hotter than VASIMR] Kelvin can be converted to Celsius by subtracting 273 degrees, since Kelvin begins at absolute zero.  In this example, that is an insignificant difference.  No need to convert this to electricity and back again to heat, wouldn't you think?


Update:

Anybody interested in what I've written about Focus Fusion can put it into the Search the blog google gadget at the top of the page.  Several posts about Focus Fusion will pop up.  As a matter of fact, I did this myself and decided to put a portion of one of my posts up here (cuz I like it so much).  This is from here.

Fusion rockets have to have better alpha he said. He says his generator weighs 3 tons. If putting large fusion rocket, would probably set up a circuit from a single bunch of capacitors. A whole cycle is 8 microsends. For a single electrode, it would melt. In theory, could put a bunch of electrodes to fire off a single capacitor for a better higher energy to mass ratio. Need a switching system. Fire the electrodes in some type of sequence. Get orders of magnitude more energy. (my comment inserted here: this is what I was thinking about, good to hear that it may be feasible) [italics added]

This is in continuation of a proposition discussed here. (fusion rockets)
