As far as the lack of reproducibility and solid evidence goes; it's been a long torturous path but it does appear that reproducibility for experienced researchers is now very high. Eg watch Mike McKubre's excellent lecture: http://ecatnews.com/?p=1430 where he describes the empirical equation and un...

So for useful power we need a reaction chamber roughly 14 meters across. That is way too large for use in a fusion powered rocket... Perhaps using D-D (and dealing with the neutronic mess) rather than pB11 would allow for a small enough reaction chamber to use in an interplanetary rocket. Why would...

Unfortunately they haven't yet matched the output of the PF1000 machine, and haven't moved beyond the known scaling laws or saturation limits. http://www.mdpi.com/1996-1073/3/4/711/ I applaud their open approach, but it is hard to see where the required breakthrough is going to come from - the above...

One piece of qualitative evidence, which is certainly not sufficient to adequately prove or disprove the simulation result, is the observed venting of the square e-cat in the september test. If you watch this video from around 6:30 you will note that there are many questions that remain unanswered....

From what I see on the construction of the demo reactor, Who in their right mind would buy it (for a utility purpose). It's only value if it works is to be torn down and reverse engineered, that's all, and I am sure Rossi would have legal's in place to prevent capitalizing on that. If the above is ...

If that aluminum trick is used, then where do you propose all the H2 was vented? Also, the oxide layer would interfere with all the metal getting into the reaction. If aluminium powder is hot enough/fine enough it burns/reacts. Could vent hydrogen with steam - though a bit dangerous, or perhaps rea...

A few examples, on the input side: -poor intensity measurement -one or more cells hiding a pre-loaded battery (fraud) -hidden micro-wave emission (fraud) -poor measurement of the cold water temp (due to sensor-fluid interface or due to sensor itself) -poor measurement of the flow in the secondary c...

Ridiculous to stop it after 4 hours when you have spent so much time organising the event and particularly after the many hours spent electrically heating it (with similar power output). There would be no problem finding 1000's of people who would be willing to monitor it for days to establish the s...

Looks like today could finally be the day to remove doubt. According to a number of tweets it is running in self sustaining mode. Nyteknik will have first dibs on reporting story tonight/tomorrow.

Could you get away with using toroidal billets of superconductor to eliminate fabrication problems? Put those billets inside insulated cryostats. While warm insert them axially between two high field helmholtz coil solenoids to create a large flux through toroid bore. Cool cyrostat below superconduc...

For cheaper testing purposes liquid helium cooled pulsed coils make a lot of sense, at 10K it appears that very pure copper can have less than 0.01% of room temp conductivity: http://indico.cern.ch/getFile.py/access?sessionId=1&resId=0&materialId=1&confId=90787 And it is a lot cheaper and easier to ...

Their info release is very short on substance, no experimental data or theoretical justifications, just a lot of hand wringing about CO2 and a few claims of breakthroughs. I guess we should all just take their word for it and give them a lot of money. Sadly a lot of people will probably do just that...

As for why I used a flywheel - basically it's because, given working Mach-effect technology at a good thrust efficiency, this setup is an eminently practical steady-state power generation scheme, and it is thus very easy to understand the energy balance. Linear acceleration can illustrate the point...

That's interesting.

Be even more interesting if we knew who CSMN was (getting a bit sick of opaque acronyms on the web)

Old 1998 paper (submitted 1996) where Focardi, Piantelli et al report 30-60W out of a sealed 50cc reaction vessel loaded with a few nickel plated metal rods and roughly 1 bar hydrogen heated to 700K by a resistor: http://www.lenr-canr.org/acrobat/FocardiSlargeexces.pdf Note there is no 'secret sauce...
