ATTN: ALL MAJOR POWERHEAD MANUFACTURERS

[tsav87]

Here's an idea to any and all manufacturers of aquarium powerheads. Wireless Electricity.

Put the pump propeller and motor inside of the tank, on a swivel to make it directional, hold it with a magnet from the outside, have a power cord attached to the outside magnet and supply wireless electricity to the motor inside of the aquarium. Boom, no wires, and you could point it in any direction.

There, that's my idea. No idea if it's possible, but.....maybe...

Thoughts anyone?

 

[Crabs McJones]

Interesting idea. I think the closest that they'll ever come to that would be the ecotech vortechs. Problem is that you can't really send electricity through glass into water into a motor. As soon as the electricity hits the water it's going to disburse everywhere as water is a great conductor of electricity. So not only will the motor get the juice, so will everything in the tank.

 

[tsav87]

Well, maybe. Wireless electricity works differently than AC and DC.

Cant watch the video at the moment, but all of his demonstrations are in air though aren't they? Not sure if doing it through water (especially saltwater) changes anything.

 

[tsav87]

Yes it is through air. But we aren't talking much water that it would be passing through.

 

[tsav87]

I'm no expert by any means, but there has to be a transmitter and a receiver for this to work, what happens in between, I don't know.

As explained by crabs, once the electricity hits the water ( especially saltwater), the whole tank is electrified. No matter how small the distance is.

 

[tsav87]

It isn't electricity, it's a magnetic field.

 

[tsav87]

In inductive coupling (electromagnetic induction[19][40] or inductive power transfer, IPT), power is transferred between coils of wire by a magnetic field.[16] The transmitter and receiver coils together form a transformer[16][19] (see diagram). An alternating current (AC) through the transmitter coil (L1) creates an oscillating magnetic field (B) by Ampere's law. The magnetic field passes through the receiving coil (L2), where it induces an alternating EMF (voltage) by Faraday's law of induction, which creates an alternating current in the receiver.[13][40] The induced alternating current may either drive the load directly, or be rectified to direct current (DC) by a rectifier in the receiver, which drives the load. A few systems, such as electric toothbrush charging stands, work at 50/60 Hz so AC mains current is applied directly to the transmitter coil, but in most systems an electronic oscillator generates a higher frequency AC current which drives the coil, because transmission efficiency improves with frequency.[40]

I would think Ecotech would have made something by now if it were possible.

 

[mta_morrow]

It's very similar to induction...…..it will not work through water

Satisfaction with the status quo halts innovation. ;Shamefullyembarrased

Would love to hear from them or anyone else who has thought or tried to do this.

But magnetism works through glass and water? Is this totally different? Again, I am nobody.

 

[tsav87]

Hmmm, wirelesses electricity under water.

Magnets work much differently.

A magnetic field is totally different than inducing electricity.

I hear ya, but it’s still a “no can do”

You are a “somebody”, not a “nobody”.

Somebody asked a good question

Nobody never asks!

.

Then do something about it.

 

[tsav87]

Well Somebody would like to know the why behind the answer of "no can do"

I want to learn something new today. ;Smuggrin

So basically if someone were to design a new wetside cover for an MP10/40/60 where you could direct the output stream ... goal accomplished?
