Re: Superfluid Helium

As a practical matter, the resources needed to make and keep the super-fluid and the technical challenges for extracting even the most minuscule amounts of energy from the system are extreme and lossy. So in short, yes, you could extract energy from the system, but it'd never be over unity or perpetual motion accounting for all inputs (gravity being a big one in this case.) Efficiency? HA!

Objection. :) You are never producing energy in any system (in the more practical classical sense anyway, theoretically, there may be ways.) As for the friction argument, I'm not so sure, since a super-fluid has no viscosity and frictionless. In the case of the Helium II fountain, you could extract minute amounts of power from the system in theory (less than the gravity pulling the fluid down from the upward flow.)

well that makes a cheap fountain for home

No thanks JaimeChootheJuBu, I'll stick to Robots, Solar, and Nuclear Power. It's easier.
LOLOLOLOLOLOL.

You two are kinda on the right track. I holds energy ALMOST forever. (possibly longer than the age of the universe!) But as soon as you take energy out of the system, you take energy out of the system... So, there's no energy being created from nothing. But as for keeping energy, get a project started and check on it in say: 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years...

ryanhaart, Your right it still would'nt work.
Once friction is introduced it would create heat. Increasing the temperature of the superfluid. Changing its characteristics. stoping the flow. Oh well back to one.

ryanhaart, after thinking it over I have come to the conclution that we CAN NOT produce energy WITHOUT at least (2) elements of earth.
Elaboration: Heat and Friction. Gravity and Friction. Heat and Gravity, or any Combonation. The question is will this Foutian flow, if friction is introduced into the flow. The superfluid seems to respond to gravity as most liquids would.

ryanhaart, That makes sense. Friction and/or Heat and/or Gravity. Yea, but we're getting close. or are we??

woah
intense...
defy gravity!

The frictionless fountain of superfluid helium is a perpetum mobile. The same perpetual phenomenons occur with superconductivity. Currents induced in a superconducting ring have been demonstrated to continue for months. The laws of physics do not forbid a self-contained perpetual motion. However, you cannot extract any energy from this. If you tried, the motion (or in case of superconductivity, the circular current) would stop.

There is if you do it in deep space (2-3 kelvins)

BBC FTW!, high quality stuff... please post more.
