STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

So do ultra capacitors. So why are they ignoring that.

Capacitors are very linear, and the energy is 0.5*C*V^2.  The battery that Steorn uses is considered drained at 1.2V. Huge difference.  It's well known that batteries are non-linear and do not resonant nearly as much as a capacitor.

Surely a 50$ ultra capacitors the size of a D cell battery would end all speculation.

A $50 bcap1500 ultracapacitor has 1500 farads and has as much energy as a 1500mAh battery. People would complain. Maybe if they had a smaller capacitor, say 100000 uF, not that many people would complain, but then again we have the resonance issue.

do this at 100.000 rpm (10 times speed of modern HDD) and you have yourself a winner in the collapse field theory. That's why they can't prove you for real the COP>1 but they want to sell patents (the idea works) to interested companies who can do that kind of RPM. Remember what Sean was talking about all along the presentation? (HDD)

Resonance happens when the capacitor gets depleted, but with these high capacitance ucaps they won't get near depletion during the on state. As for people complaining, all steorn has to show is the voltage rising and maybe discharging through a zener to not explode the cap.

I don't know how much current the eorbo uses during the on state. But even if it's 10 amps, and the on time is 0.1s a 350 F ucap would only drop 3mV in voltage. Either Steorn doesn't know of the existence of ultra caps or they are hiding something.

A capacitor resonates regardless. See the two attached images. Top graph is for a capacitor of 100000uF. The bottom graph is for a battery. There's no need to simulate a large ultra capacitor because they hold a lot of energy like batteries, so people will complain.

The only reason people are saying to use a capacitor is because it does not hold a lot of energy like a battery. A 350F cap @ 1.3V holds a lot of energy.


The drop in voltage is significant in the capacitor simulation. The current drop is low, but Sean has made it clear that it has to be very constant.

I'm not saying resonance is the reason, but that it will exist if a cap is used.

I'm curious what Sean means when he mentions that the use of a torroid is irrelevant in http://www.steorn.com/forum/comments.php?DiscussionID=62319&page=1#Item_14. Anyone have an explanation?
