Chemists warming to Cold Fusion.

At Annual Convention, Chemists Warm to Cold Fusion

Image

Looking for new energy solutions, scientists are increasingly embracing the idea of cold fusion, once considered a junk science along the lines of alchemy. "Cold fusion" describes the nuclear fusion of atoms at close to room temperatures, as opposed to the epic temperatures at which nuclei fuse inside stars. If realized on a practical scale, it could provide the world with a virtually limitless source of energy.

Note the Calorimeter measuring 50 Megawatts. :)

Did some one make the mW vs MW mistake again?

Snippet from article:
He used the system to measure what happened when he charged an ammonium chloride solution, and found that it formed nitrogen trichloride and 50 megawatts of excess power.
The author didn't know her units, and neither did the editor. Not that I'd expect much from popsci, but sheesh.

How much solution did he charge up? A pint is one thing, 20 gallons is quite another. At 50 MW, how much solution would vaporize?

Science Daily covered the conference as well. Mega or Mili aside, it looks like there's some interesting research being done:

The article lists presentations at the bottom, some of which might be searched up to find out more specific actual details.

.. all of it, along with most of the lab, i should imagine.

You beat me to it.

... though to be fair, no one said anything about the time period involved...

Lets see... 50 MegaWatts.
That would power a 1000 W space heater for 50,000 seconds, or ~15 hrs.,
or a ~70,000 HP jet engine for ~ 1 second. Turn that on in a lab and things would get exciting.

Uh. MW is a rate.

He could have used a swimming pool for his experiment... :)

This calculation confuses me. Those 50 MegaWatts up there are missing a time component in there, or am I missing something. 50MW for a picosecond is a lot less energy than 50MW for an hour... I dont think you can take the 50MW and turn them into Watts/hour just like that...

50 megawatt = 180 000 000 000 joule/hour,
50 megawatt = 50 000 000 joule/second
by my online units converter.

From this I suspect that the experimental measurement was on the order of seconds to minutes and that those who posit a typo (mW vs MW) are correct.

Well I do my numbers with MWh, KWh, etc. Not MW and KW.
If you had said it had produced so and so many MWh and then gone on with your calculation, I would have understood.
A gallon of gas produces so and so many KWh not KW.
