Taking stock of cold fusion

A guy walks up to me at a par­ty. A busi­ness type. I think his name was McGuire.

Chet.”

Yes.”

I just want to say one word to you. Just one word.”

Yes?”

Fusion.”

A long pause.

I asked, “Exact­ly how do you mean it?”

There’s a great future in cold fusion. Think about it. Will you think about it?”

I hes­i­tat­ed. “Yes, I will.”

He slapped me on the back: “ ‘Nuff said. That’s a deal.” He left to rejoin the par­ty. I stood there, slack-jawed.

The last time some­one gave me a one-word tip for finan­cial suc­cess was back in 1958, when I was a young grad­u­ate. The word then was “plas­tics.” I dropped the ball. I did­n’t invest.

This time I was deter­mined not to fum­ble. I con­sid­ered what I knew about cold fusion.

Three years ago, chemists B. Stan­ley Pons and Mar­tin Fleis­chmann cre­at­ed a furor with their claim to have pro­duced ener­gy by fus­ing hydro­gen into heli­um in a sim­ple table-top exper­i­ment at room tem­per­a­ture — so-called cold fusion.

Fusion is the source of ener­gy that pow­ers the stars. The fuel for the fusion reac­tion is cheap, inex­haustible hydro­gen. The “ash” of the reac­tion is harm­less heli­um. If cold fusion worked, it could answer the world’s ener­gy needs forever.

The trou­ble is, cur­rent the­o­ries of physics pre­dict that hydro­gen fusion hap­pens only at tem­per­a­tures of tens of mil­lions of degrees. Such tem­per­a­tures occur nat­u­ral­ly in the cores of stars, but they can be pro­duced on Earth only with nuclear explo­sions or colos­sal­ly expen­sive fusion reactors.

Pons and Fleis­chmann claimed to have har­nessed fusion ener­gy with an appa­ra­tus con­sist­ing of a jar of heavy water (water made with deu­teri­um, a heavy form of hydro­gen) into which was dunked an elec­tric cur­rent-car­ry­ing rod of pal­la­di­um. Cheap. Portable. Sim­ple as pie.

Physi­cists exam­ined the claim of fusion in a jar and decid­ed it lacked mer­it. The exper­i­ments of Pons and Fleis­chmann could not be reli­ably repli­cat­ed. The furor passed.

Now this guy McGuire was giv­ing me a red-hot invest­ment tip. Did he know some­thing I did­n’t know? I called my broth­er-in-law, the stockbroker.

Joe,” I said. “What do you know about cold fusion?”

Hot top­ic.”

How so?”

Lots of sto­ries in the busi­ness press late­ly — the Wall Street Jour­nal, Busi­ness Week. Almost every day there’s stuff on my elec­tron­ic bul­letin board about suc­cess­ful cold fusion exper­i­ments. The finan­cial com­mu­ni­ty sniffs money.”

That’s fun­ny. There’s been almost noth­ing about cold fusion in the sci­en­tif­ic lit­er­a­ture, at least not since the Pons and Fleis­chmann hoopla died down.”

You know those physi­cists, Chet. They’re con­ser­v­a­tive as hell. Scared to admit they don’t under­stand what’s going on. They resent the fact that it is most­ly chemists and engi­neers who are doing the cold-fusion research. And they’ve got vest­ed inter­ests in expen­sive hot fusion projects. They’ll go right on debunk­ing cold fusion until the Japan­ese have a cor­ner on the mar­ket. Take my word for it, this mar­ket will make Per­sian Gulf oil look like small potatoes.”

What do you mean?”

There was a cold-fusion con­fer­ence in Japan late­ly. Sci­en­tists from around the world report­ed suc­cess­ful pro­duc­tion of ener­gy in exper­i­ments involv­ing hydro­gen, pal­la­di­um rods, mag­ne­sium-oxide-coat­ed pal­la­di­um wafers, and God knows what else. Some peo­ple claim to get 10 times more pow­er of their exper­i­ments that what goes in — with a device the size of an auto­mo­bile bat­tery. It’s the clos­est thing to per­pet­u­al motion I’ve seen yet.”

Cold fusion does smack of the old per­pet­u­al motion scam.”

Come on, Chet, get with it. It’s no acci­dent the con­fer­ence was held in Japan. Nip­pon Tele­graph & Tele­phone Cor­po­ra­tion, the Japan­ese telecom­mu­ni­ca­tions giant, is doing cold fusion exper­i­ments and claims suc­cess. The Toy­ota Motor Cor­po­ra­tion has a sub­sidiary work­ing on cold fusion. It is said that Japan­ese mon­ey is behind the new lab­o­ra­to­ry that Pons and Fleis­chmann have set up in France. By the time Amer­i­cans wake up and smell the cof­fee, the Japan­ese will be light-years ahead.”

What do you suggest?”

Give me a thou­sand bucks, 10,000, what­ev­er you can afford. I’ll put it into Nip­pon stock, or pal­la­di­um futures, or cold-fusion ven­ture cap­i­tal. When the new tech­nol­o­gy takes off, you’ll make a killing.”

Sor­ry, Joe, but it sounds too risky to me. Every­thing I know about physics sug­gests that hydro­gen fusion at room-tem­per­a­ture is extra­or­di­nar­i­ly unlike­ly, prob­a­bly impos­si­ble. The cold-fusion boom­let looks to me sus­pi­cious­ly like a com­bi­na­tion of wish­ful think­ing, con­t­a­m­i­nat­ed data, and slop­py exper­i­men­tal tech­nique. Some­thing may be hap­pen­ing in those labs, but I doubt if it’s fusion. I think I’ll keep my mon­ey in a sav­ings account.”

OK, but don’t say lat­er that I did­n’t give you a chance to get in on the ground floor.”

I won’t. Remem­ber, I missed out on plas­tics, too.”
