How your Kurt Kinetic fluid unit works
Pretty old video but a search didn't show it posted already.
The magnets are cool. https://www.youtube.com/watch?v=NZkEezODNbo |

That's pretty cool.
I'm sure to have some time to think about that when rolling on mine in the living room during February rains on the Pacific coast... |

One failure mode of automobile water pumps is the seals. One wonders whether, if car water pumps were designed this way, it would eliminate these failures and less likely to leave you stranded.

Maybe too much torque in a car for the magnets to handle? That's my uneducated guess.

there is no way they would do something like this in a car design. Simply because of money. Seal failure is slow and generally doesn't cause harm anyway.

I love my kurt kinetic rock n roll. Great product.

can't see water/anti-freeze mix providing any more spin-up resistance than the silicone fluid used in the KK.

The best way to think about this is power. An automotive coolant pump needs anywhere from roughly 200W of hydraulic power to several kW of hydraulic power to do the work of pumping coolant through the restriction of the engine water jacket and the rest of the coolant circuit branches. The low end above is for vehicles that use electric main pumps (where the electric machine can be rated as low as 400W or so) and the high end is for large engines with conventional pumps (where the mechanical input from the accessory drive can be close to 10kW.)
For most of us, the sustained power dissipation in a trainer unit is 200-300W. Jan G. Quote:
