Italian scientists will build up large power cold fusor for business application soon, T/F?

<r>Italian scientists Rossi and Focardi claim cold fusion success<br/> <br/> The reactor uses less than 1 gram of hydrogen and starts by consuming about 1,000 W of electricity, which is reduced to 400 W after a few minutes, according to PhysOrg report. The output of the reactor converts 292 grams of...

Re: 50 Ohm 4000W dummy load

of cause you can by parallel and series to get the power.
but rf 4000w is too large and easy radiation. and the load will has distribute parameters. is it 4w[4000mW] or 40w? not 4000w?

Re: X-Rays from Rectifiers

<t>There will be no x-ray give out when you use HV recitifier.<br/> 1] the cause of x-ray due to elelctron beam strike target, the path of telectron in the target changed by the extra energy will produce photon. this is so called x-ray.<br/> 2] you can't find such high speed electron stream in state...
