Let's see... thousands of very expensive and unreliable windmills blighting the landscape and affecting local environments while killing off birds or... some nondescript buildings "burning" some water. Oh, let's go with the windmills because... because... hmmmmmmm.

But, if you are like some people who hide under an umbrella when they hear the words "nuclear" or "fusion" [sorry, Ford], then maybe this holds promise... unless they fear "chemistry."

Navy Chemist May Have Rediscovered 'Cold Fusion'

Thursday, March 26, 2009

Twenty years ago this week, a pair of previously unknown scientists stunned the world by announcing they'd done the impossible by achieving nuclear fusion in a lab flask at room temperature.

Martin Fleischmann and Stanley Pons quickly became celebrities as the news media hailed them for discovering a cheap source of nearly limitless power. But it all fell apart as other scientists couldn't duplicate their results, and the pair later admitted they'd made mistakes in the experiments.

Now a U.S. Navy researcher, speaking on the anniversary of their announcement and in the same city where they made it, thinks Fleischmann and Pons may have been right.

In a paper presented on Monday, chemist Pamela Mosier-Boss told the annual convention of the American Chemical Society in Salt Lake City that her team had gotten "very significant" evidence of some sort of nuclear reaction.

"To our knowledge, this is the first scientific report of the production of highly energetic neutrons from an LENR device," said Mosier-Boss, a researcher at the Navy's Space and Naval Warfare Systems Center in San Diego, in a press release.

Highly energetic neutrons, which Mosier-Boss' team detected using special neutron-trapping plastic, are emitted from atoms splitting apart — or fusing together — and indicate that a serious nuclear reaction is going on.

"LENR" stands for "low energy nuclear reaction," which in this case happens in a lab flask containing palladium chloride mixed with deuterium, or "heavy water" made with a special form of hydrogen — the same setup Fleischmann and Pons used.

When an electrode was dipped into the flask and the power switched on, Mosier-Boss said, odd patterns of triple neutron strikes would appear on the adjacent plastic receptor.

Fleischmann and Pons' results centered on unexplainable excess heat resulting from the reaction. Mosier-Boss didn't get that, but the neutrons are even more significant.

"People have always asked 'Where's the neutrons?'" Mosier-Boss said in the press release. "If you have fusion going on, then you have to have neutrons. We now have evidence that there are neutrons present in these LENR reactions."

Nuclear fusion occurs at the center of stars, which fuse hydrogen nuclei together to create helium. It creates enormous amounts of energy, but it takes huge amounts of heat to happen at all.

Humans have so far generated the necessary heat only by detonating fission-based atomic bombs, which heat up cores of special two-neutron hydrogen to create a second, fusion-based explosion — a hydrogen bomb.

Decades of efforts to create controlled nuclear fusion, which could power reactors endlessly using cheap, abundant hydrogen, have so far been fruitless.

Go back to 1999-2000 and see what the Fed did. They are following the same pattern for 2005-06. If it ain't broke, the Fed will fix it... and good!
August 29, 2006 The Federal Reserve always acts on old information... and is the only cause of U.S. recessions.
December 5, 2006 Last spring I wrote about what I saw to be a sharp downturn in the economy in the "rustbelt" states, particularly Michigan.
March 28, 2007
The Federal Reserve sees no need to cut interest rates in the light of adverse recent economic data, Ben Bernanke said on Wednesday.
The Fed chairman said ”to date, the incoming data have supported the view that the current stance of policy is likely to foster sustainable economic growth and a gradual ebbing in core inflation”.

July 21, 2007 My guess is that if there is an interest rate change, a cut is more likely than an increase. The key variables to be watching at this point are real estate prices and the inventory of unsold homes.
August 11, 2007 I suspect that within 6 months the Federal Reserve will be forced to lower interest rates before housing becomes a black hole.
September 11, 2007 It only means that the overall process has flaws guaranteeing it will be slow in responding to changes in the economy... and tend to over-react as a result.
September 18, 2007 I think a 4% rate is really what is needed to turn the economy back on the right course. The rate may not get there, but more cuts will be needed with employment rates down and foreclosure rates up.
October 25, 2007 How long will it be before I will be able to write: "The Federal Reserve lowered its lending rate to 4% in response to the collapse of the U.S. housing market and massive numbers of foreclosures that threaten the banking and mortgage sectors."
"Should the elevated turbulence persist, it would increase the possibility of further tightening in financial conditions for households and businesses," he said.

"Uncertainties about the economic outlook are unusually high right now," he said. "These uncertainties require flexible and pragmatic policymaking -- nimble is the adjective I used a few weeks ago."

December 11, 2007 Somehow the Fed misses the obvious.

December 13, 2007 [from The Christian Science Monitor]
"The odds of a recession are now above 50 percent," says Mark Zandi, chief economist at Moody's "We are right on the edge of a recession in part because of the Fed's reluctance to reduce interest rates more aggressively." [see my comments of September 11]
January 7, 2008 The real problem now is that consumers can't rescue the economy and manufacturing, which is already weakening, will continue to weaken. We've gutted the forces that could avoid a downturn. The question is not whether there will be a recession, but can it be dampened sufficiently so that it is very short.
January 11, 2008 This is death by a thousand cuts.
January 13, 2008 [N.Y. Times]
“The question is not whether we will have a recession, but how deep and prolonged it will be,” said David Rosenberg, the chief North American economist at Merrill Lynch. “Even if the Fed’s moves are going to work, it will not show up until the later part of 2008 or 2009.
January 17, 2008 A few days ago, Anna Schwartz, nonagenarian economist, implicated the Federal Reserve as the cause of the present lending crisis [from the Telegraph - UK]:
The high priestess of US monetarism - a revered figure at the Fed - says the central bank is itself the chief cause of the credit bubble, and now seems stunned as the consequences of its own actions engulf the financial system. "The new group at the Fed is not equal to the problem that faces it," she says, daring to utter a thought that fellow critics mostly utter sotto voce.
January 22, 2008 The cut has become infected and a limb is in danger. Ben Bernanke is panicking and the Fed has its emergency triage team cutting rates... this time by 3/4%. ...

What should the Federal Reserve do now? Step back... and don't be so anxious to raise rates at the first sign of economic improvement.
Individuals and businesses need stability in their financial cost structures so that they can plan effectively and keep their ships afloat. Wildly fluctuating rates... regardless of what the absolute levels are... create problems. Either too much spending or too much fear. It's just not that difficult to comprehend. Why has it been so difficult for the Fed?
