Just listened to the Lerner podcast. Not much news to those familiar with their earlier presentations, except that they are currently 'baking' the oxygen and water out of their tungsten electrodes, and ought to be done next Monday. I guess some chance that there will be more substantial news in thei...

I'm quite surprised that there has been no comment on one thing which caught my eye in the paper: they talk of an 'avalanche' reaction with energetic alphas provoking further reactions. Isn't that a chain reaction? Is the gain so high because they have managed to provoke a small (ok very small!) exp...

Since the topic is 'LENR is Real' not just 'Rossi acts like a fraud', I thought this was interesting.

Mitsubishi Heavy, Toyota, Nissan are pretty real...

Oops. Apologies, you're right, the currents are opposed but I realise now the B-fields actually reinforce where the rings approach, so there is no dead spot.

R.

Yes, you're right, my mistake: if the top & bottom coils are set to match the direction of flow where they meet the sides, the corners don't have a complete 'virtual' flow. But that kind of gets me back to where I started: we are now up to 12 dead spots, because every coil's flow is going in the opp...

OK, thanks. I hadn't appreciated how the cubic arrangement looks if the 'side' faces all circulate the same way relative to the cube centre, opposite to the top and bottom. At the cost of 4 apparent dead spots where the sides approach, the arrangement approximates the truncated cube shown in the pap...

Sorry if this was asked an answered eons ago, but the FAQ link is currently broken... Why is a cubic arrangement of coils considered a good idea? Geometrically, the dual shape, a regular tetrahedral 'diamond' seems much better, for the following reasons ( I am assuming current circulates in one dire...

Apparently from Ed Storms. Quite interesting.

Sigh. It comes to something when between the EMDrive,
Rossi, Sonny White, and aliens building a truncated
Pyramid on Pluto, it isn't clear which is the most crazy
thing to believe in...

I have a 2.5 kW solar system in Scotland (for the subsidy!).

I calculate I could pay $2400 for 4 kWh of diurnal storage, or $4800 for 20kwh of weekly storage, at local power prices.

The powerwall seems reasonably well targeted, but for the installation cost!

R.

With that number of people, refering to e.g. 'the engineering department' would be kind of disingenuous... R.

It's late on Friday night, after the bulk of a bottle of red wine, so I contribute this with some trepidation as to how it will look in the morning. I hope you will all still respect me in the morning. Two points: Einstein made us choose between Newtonian mechanics and Electrodynamics. Doubtless it ...

(V2 X (r X V1)), of course! R.

GIThruster: the guy whose textbook I quoted (P.C.Clemmow of Cambridge University), as well as DeltaV, explicitly says that momentum conservation can be recovered. Tuval and Yehalom say the same thing at the start of their paper in the revised format. Nonetheless, the mechanical system will experienc...

Back to the root topic I'm afraid... I just read the paper - the Arxiv version. The says nothing I could spot about reaction forces, but simply does a careful calculation of the total force on two current loops in the case where the Lorentz force propagates at the speed of light. The answer (equatio...
