Some cold water for cold fusion

The grand old man of sci­ence fic­tion, Sir Arthur C. Clarke, recent­ly weighed in once again with the opin­ion that there may be some­thing to cold fusion.

Cold fusion? I thought that will‑o’-the wisp had been laid to rest.

Back in 1989, Stan­ley Pons and Mar­tin Fleis­chmann, chemists at Uni­ver­si­ty of Utah, set the world abuzz with their claim to have pro­duced nuclear ener­gy in a sim­ple table­top experiment.

What was so excit­ing? When the nuclei of light ele­ments fuse, they release ener­gy. But it takes a heck of a high tem­per­a­ture to make it hap­pen, mil­lions of degrees. Nuclei are pos­i­tive­ly charged. To make them fuse, they have to be mov­ing fast enough to over­come their mutu­al elec­tri­cal repulsion.

This hap­pens in the blaz­ing hot cores of stars when hydro­gen nuclei — pro­tons — fuse to form heli­um. Pro­ton fusion is the source of the sun’s heat and light, and ulti­mate­ly the source of ener­gy for almost all life on Earth.

Researchers have been work­ing for years — build­ing colos­sal appa­ra­tus­es at stag­ger­ing expense — to har­ness the ener­gy of hot fusion, so far with­out much prac­ti­cal suc­cess. Thus the excite­ment when Pons and Fleis­chmann claimed to have caused hydro­gen nuclei to fuse at room tem­per­a­ture, in an inex­pen­sive appa­ra­tus that any­one could build.

The prospect of inex­haustible, near­ly free, non­pol­lut­ing ener­gy was splashed across the front pages of news­pa­pers worldwide.

But many sci­en­tists, espe­cial­ly physi­cists, were skep­ti­cal. The Utah exper­i­ments seemed to vio­late every known law of nuclear physics. It all seemed too easy. And besides, what did chemists know about top­ics that prop­er­ly belonged to physicists?

Phras­es like “junk sci­ence” and “patho­log­i­cal sci­ence” were bandied about.

After an ini­tial flur­ry of excite­ment, the hub­bub resided. The exper­i­ments turned out to be noto­ri­ous­ly dif­fi­cult to repro­duce. Only believ­ers seemed to get pos­i­tive results. Even­tu­al­ly, the sci­en­tif­ic com­mu­ni­ty arrived at a con­sen­sus: Cold fusion was a bust.

But believ­ers in cold fusion did not give up so eas­i­ly. They accused the “Church of Sci­ence” of squelch­ing any­thing that did not fit the offi­cial ortho­doxy. They remind­ed us again and again of the fates of oth­er unortho­dox sci­en­tists — Galileo, for exam­ple, or Alfred Wegen­er, the father of con­ti­nen­tal drift, whose ideas were scorned by their contemporaries.

No one has been a more ardent cham­pi­on of cold fusion than Eugene Mallove, a sci­ence jour­nal­ist who pub­lish­es cold-fusion-boost­ing Infi­nite Ener­gy mag­a­zine out of Con­cord, N.H. For some rea­son, I have been on the mag­a­zine’s mail­ing list since its incep­tion six years ago. While I can­not claim to be an avid read­er, I usu­al­ly flip though the pages to see what’s going on.

What’s going on is all smoke and no fire.

Every year the cold fusion com­mu­ni­ty gath­ers for an inter­na­tion­al con­fer­ence on recent research, and every year the mag­a­zine breath­less­ly reports world-shak­ing break­throughs. Mean­while, the num­ber of sci­en­tists attend­ing the con­fer­ences dwin­dles. Accord­ing to a recent issue of Infi­nite Ener­gy, most atten­dees are retired pro­fes­sors 65 to 75 years old. It would seem the bright young physi­cists and chemists who stand to gain the most from cold fusion break­throughs know a dead end when they see one.

Infi­nite Ener­gy can be applaud­ed for its inter­est in alter­nate ener­gy sources, and sci­ence can use an occa­sion­al icon­o­clast, but the mag­a­zine should set its bar higher.

A glance through any issue shows what’s wrong. In addi­tion to reports on cold fusion, there are ads and arti­cles tout­ing per­pet­u­al motion, UFOs, anti­grav­i­ty, Atlantis, water mem­o­ry, and oth­er flaky ideas. You can’t dress up in a clown suit and expect to be tak­en seriously.

For years, Mallove has been pre­dict­ing in his edi­to­ri­als the immi­nent arrival of a com­mer­cial­ly viable cold-fusion pow­er source, the sort of thing we could all have in our base­ments to sup­ply our homes with essen­tial­ly free ener­gy. One by one, new start-up com­pa­nies have promised prac­ti­cal cold fusion tech­nolo­gies. One by one, the promis­es have fall­en silent.

I have nei­ther the knowl­edge nor the time to eval­u­ate a lot of the stuff in the mag­a­zine, but I think I know shaky sci­ence when I see it. I’ll put my mon­ey where my mouth is. I here­by promise to write Infi­nite Ener­gy a check for $10,000 when the first home cold-fusion pow­er unit shows up for sale in Sears, or any oth­er mass-mar­ket­ing store, or when the first kilo­watt of cold-fusion elec­tric­i­ty enters the pow­er grid.

Hey, for me it’s a no-lose propo­si­tion. If cold fusion enthu­si­asts are chas­ing a will‑o’-the-wisp, then my 10 grand is safe. If I’m wrong, I’ll save 10 grand on my ener­gy bills.

As for Authur C. Clarke, he also pre­dict­ed that humans would be trav­el­ing to Jupiter by 2001, on a space­ship run by a will­ful com­put­er. That’s not going to hap­pen either.


As of 2022, suc­cess­ful cold fusion reac­tions have not been repro­duced. Infi­nite Ener­gy mag­a­zine still car­ries the torch, how­ev­er. ‑Ed.
