Or, by the use of stonking great electromagnets, the tap can be dispensed with.
Water is susceptible to magnetic forces, and so the flow could be halted entirely, or by [insert percentage of your choice] flow rate.
No more of them dripping taps, or ones that are a bugger to turn on or off.
May
or may not come with little levitating frog to indicate flow rate, so long as they get a free meal, they ain't bothered.
Sales plug comes with "Now with extra tetrahedrality!!!" according to one London university. Link

London something something university, so it must be true. [not_morrison_rm, Dec 11 2016]

What is Dialectical Materialism and how is it related to plumbing ? |
|
| |
Ah, you're thinking of Diamante Mesopotamians. |
|
| |
If that stuff is true why don't MRI machines kill you? |
|
| |
Ah .. they can - but they don't. |
|
| |
Because what they're doing is lulling you all into a false sense of security. |
|
| |
...and even if the flow doesn't change much, just
think how many mpg you'll get. |

Call me boring, but this idea should actually work, don't ask me what the huge magnetic fields would do (realises no one has a CRT monitor or a mechanical watch these days)...oh. |

Anyway, you could even do pumping water around with a kind of magnetic peristaltic effect, getting water with a high dissolved iron content would help, and would be more humane than just jamming a load of frogs into the water pipe to affect a seal*. |

*No, not a seal as in a pinniped. |

//water with a high dissolved iron content// I'm not at all sure that dissolved iron (which would iron ions) would make water magnetic. |

The helical linear induction pump is Baked and WKTE for pumping liquid metals like NaK, for - amongst other applications - fission reactor cooling. |
|
| |
They can also be used for ferrofluids, mercury, and some molten salts. |

Hmm, it might or might not work, as iron is attracted by magnets, whereas water is repelled by magnets. |
