Has anyone had a chance to check out the Nov. 19 posting on DVICE, Nuclear fusion: Coming to a basement near you soon. We seem to be be getting more attention which is great. I wonder if Eric and staff found any inaccuracies? omissions?

Do you have a link for that?

Wait!  Got it:  http://dvice.com/archives/2009/11/nuclear-fusion.php

Thanks!

I posted a reply to the site as follows:

The Focus Fusion process is designed to work with hydrogen and Boron-11, not neutrons. The protons (ionized hydrogren) and boron fuse, then decay into 3 heliums. NB the early experiments will be done just with deuterium to verify the plasma conditions.

The device is designed to be pulsed at several hundred Hz. So although a small amount of energy is released per pulse, a focus fusion device running at ~300Hz could produce a few MW of nett power output. If the experiments verify the theoretical models.

Conventionally nuclear reactions involving light nuclei are termed fusion and those over the mass of iron are fission. This is due to the shape of the binding energy per nucleon curve http://en.wikipedia.org/wiki/Binding_energy#Nuclear_binding_energy
Most nuclear reactions involve combining two nuclei (or a nucleus and a neutron or proton) followed by the breakup due to the amount of energy available due to the mass difference between the compound nucleus and the final end products.

The beauty of the focus fusion approach is that there are no appreciable neutrons or radioactive products produced. Also since the products are all charged the energy can be recovered much more directly to electricity than conventional fission power stations, and proposed tokamak fusion designs which rely on heating water to drive steam turbines.

Jamesr’s right they use the term neutron instead of proton to describe the process in the DVICE blog. Still they seem to get most of the broad brushstokes correct. More importantly its positive.  Perhaps someone could respond to that issue and others (ERIC)? and we could get another blog out of them.

maybe because a proton decays into a neutron or other way round, beta dacay :/
