How easy is it really to get steam from 300 Watts only? The difference between 12kW and 300W must be obvious, even for the naked eye.
I'd say that this is quite a naive understanding. First of all, what was the *peak* heating for that "12 kW" result? The Ny Teknik report has 1 kW peak, reduced to 700 watts. This is easily enough to produce steam! (You can produce steam with 300 watts, it's all a question of how much, and it would only take a small amount of steam to drive water out the outlet pipe.)
Sorry, my "naked eye" doesn't see power generation. Steam, as well, is invisible, what is seen is condensed water. Ever see an ultrasonic humidifier? It seems to be "steaming," but it's just mist. It's cool.
And no reports on input power? Is it measured at the plug, before whatever electronics he uses?
The pictures shown by the blogger who was there with Krivit showed a current meter being clamped on the power wires, so, at the plug, is the short answer.
Or at the input in the reactor? If the latest and if that is RF/pulsed there is definitely a measurement issue there, much more difficult than measuring steam.
No, it's total power in, a safer, conservative value. This isn't the problem. The problem is that Rossi does have an electrical heater in there, and it's quite capable of bringing the device up to operating temperature, about 450 C. and that could be maintained above the boiling point, 100 C., with quite a bit less power.
Someone who is highly experienced might be able to tell the difference, but I wouldn't bet on it. If pure steam is coming out of a pipe, into the air, where it can be seen entirely, and where the plume disappears, a big wet spot doesn't appear, it's dry steam. The steam will be invisible right where it comes out, but will turn into vapor quickly, which is the "steam" that we see. And then, as this spreads out, it revaporizes. When you boil water on the stove, does the stove get wet around the pot? Only if I allow it to boil over!
