Can you pass electricity through Glass?

[basslover911]

^^ I would but they already make pumps like that and they are held by a patent so i can't copy it :/

Plus I want to modify my existing pumps so I can just cut off their AC cord and 'splice' this "wireless inductance" gizmo in between it.

The AC cord would carry the 120v that gets stepped down at the pump, so I would need to do this kind of thing;

AC wire -> 120vac to 12vac -> "wireless inductance" | GLASS | "wireless inductance receiver" -> 12vac to 120vac -> pump

But now I am stuck at the "wireless inductance" phase lol. need to pass 12vac to 12vac on the other side of the glass.

seriously though, why cant the leads go in through the top like a normal fish pump?

Aesthetics.

You can copy and build any patented item for your own personal use or for research without penalty. It is when you sell them, use them in a commercial setting, or even give a number of them to others that gets you in trouble.

One of the requirements of a valid patent is that others with reasonable skill are able to duplicate it from the patent description.

It is possible to drill through glass too, i.e. through the bottom, slow, with lubrication dam and special bit, google.

Note: I would replace the plug end of the pump after feeding the wire through the hole, to keep the in-tank pump power with the original sealing.

That's all I got for asthetics. Except that you could also put the tank on a vibrating table and wirelessly transmit some energy to it that way

That's what you want, but without the incredible price. Aesthetics makes or breaks an aquarium IMO. I've seen these in person, and they are awesome, certainly worth the price. But the principle on which they work is simple, and doesn't require such a hefty $$$ premium. (I know those two statements conflict, but want and need have the same analogy)

...look-up their "patent" on how the system works and see if you think it's worth your effort to attempt DIY building one for your own use.

[dcb]

yah, if you can design your own pump. 3 phase coils on the outside, pm rotor on the inside of the glass, forget all that connectivity weirdness.

There are a lot of magnetic pumps out there that have the impeller sealed off from the motor with out any direct mechanical connection, El Sid pumps are an induction pump that the only moving part is the impeller that is on the other side of a Stainless Steel plate, separated from all of the electronics.
Come to think of it, why not just a small diaphragm pump? much easier to build and on the out side of the tank you just have a coil that pulses on and off with a little iron or magnet button in the center of the diaphragm.
