Pyroelectric fusion (the other "cold" fusion)

Postby CharlesKramer » Sat Feb 06, 2010 9:55 pm

One of the possibilities raised by the Navy's recent revelations about cold fusion (or, if you prefer, LENR) is:

- the Pons/Fleishman type experiments that *do* generate heat sometimes maybe are nuclear (neutron generating, element transmuting)

- maybe such reactions are no big deal -- occurring in nature with such low levels of energy output and neutron emission that no one notices.

I recently read about a kind of fusion that maybe has been kicked around here (I didn't search) but it seems not to be discussed anywhere very often: Pyroelectric fusion

If I understand it, UNLIKE LENR

--- Pyroelectric fusion is a proven thing -- reliably reproducible

--- Pyroelectric fusion it is proven to be nuclear (measurable neutrons)

--- so far no one is talking about Pyroelectric fusion as an energy source. A source neutrons, maybe, in a small way

Like LENR of the Pons/Fleishman type, Pyroelectric fusion is low energy, countertop small science. Strictly speaking in requires heat, but it's still a "cold" reaction compared to ITER, NiF, or Polywell for that matter.

Pyroelectric fusion seems to have been proven since at least 2005, but work didn't stop then.

Enhanced pyroelectric crystal D–D nuclear fusion using tungsten nanorods
SUMMARY: Thin films of vertically aligned tungsten nanorods were used to enhance field ionization in pyroelectric crystal D–D fusion experiments resulting in increased neutron production. The tungsten nanorods were deposited on a single LiTaO3 crystal using sputter deposition at glancing angles. The combination of a single tungsten tip with a thin film of nanorods on the face of the crystal yielded about four times the number of neutrons than did either a single tip or nanorods alone.

What you are describing is the ignorance of the media, not a legitimate scientific description of pyroelectric fusion as 'cold fusion'... I mean, look at the words.. 'electricy' and 'fire'!

'Electric fusion', a phrase I am beginning to adopt, I think more appropriately reflects the nature of these techniques because an electric field can accelerate an individual fusible ion to fusible energies, but an ion cannot have a temperature because temperature is a bulk property.

An ion on its own, can be neither hot nor cold. Yet electric fusion is about the individual behaviours of individual ions so isn't really hot or cold.

So, to have called this 'cold fusion' is a media invention of phrase.

Muon catalysed fusion certainly is 'cold'. In a very real sense because it is best done at liquid deuterium/trituim densities, thus at cryogenic temperatures, let alone room temperature. 'Cold fusion' in an electrolysis cell is, literally, 'very hot' by comparison and is well above D boiling point!

Because we can.

Yeah, it is hot fusion, and it doesn't make a heck of a lot of fusion events. But I wonder if you accelerated H ions instead of deuterium, and you used a lead target, could you get some decent spallation neutrons from such a setup?
