That's agains thermodynamic laws!!!!!

Umm no theres no such thing as 'free energy' in this sense. Buy a solar cell its as close as youll get.

where did you get this video? i would like to try this out, all you college people are confusing me and im not sure wether youre saying it works or not.

lol what a retard

No, the hot air it spews forth is toxic, damages brain cells and is highly contagious to those lacking a physics education! Sadly, for some people there is no cure. >:D

so does this shit work in term of emission free energy?

Stwryrch (November 30, 1999 at 12:00 am)

The energy source must work against the back emf. This energy is not lost, but stored in the magnetic field. On the ramp down however, the field dissipates, again causing a back emf that creates a current that does dissipate all the magnetic energy as Joule heating. I cannot determine this power loss without knowing the circuits time constant (Google RL circuit). However, it appears a large field is generated and I'm sure there is more energy lost on the ramp down than the ramp up.

Yes, 1.05336 is in units of Joules. Thats willingness to learn. Multiplying by 3 pulses and then rounding gives 3.16 Joules per cycle. Watts is energy divided by the amount of time to give said energy. 3.16 Joules is given in one cycle that takes 0.6283 seconds (Notice this is not 3*0.028s). Thus, 3.16J/0.6283s = 5.03W. This however is just of Joule heating on the ramp up. The generation of the magnetic field isnt free as the solenoid self inducts in the transient state, due to Faraday's Law.

Quote: The frequency is 10 rad/s and thus one cycle is 0.6283 seconds. Therefore, the power dissipated on the ramp up of the electromagnet is 3.16/0.6283=5.03W --------------------------------------------- This is where you are so very wrong. It seems like you believe the pulse is ongoing for one whole cycle. But it is not. It's only 1.05WS (1.05J) for each cycle. 3*1.05J=3.15J... No more enery than 3.15J is input to the EM. And the continously shaft output is approx 6W. PERIOD.

Google Paul Sprain and find this: 19.8v @ 1.9A = 37.62W each pulse is 28 milliseconds = 1.05 W Paul Sprain world physics - 19.8V*1.9A*0.028s=1.05 Watts Real world physics ---------- 19.8V*1.9A*0.028s=1.05 Joules P=IV=E/t is something you should have learned in a High School physics class. At the very least, google power or look up in a physics book this very simple relationship and then you will know more about physics than Paul Sprain.
