@AutoPap Fully agree. We kid ourselves we make money on cars. Some have been good - best ever for me my CGT. But take in to account all the costs, including the opportunity cost of the cash, and it’s hard to make a real profit. My view is if I get back what I paid for it that’s a win

Scientists have reinvented the gear for the first time in 5,000 years.

How? By swapping out solid mechanical teeth for dynamic fluid flows.

For thousands of years, machines have depended on the exact meshing of physical gear teeth to transmit motion—a principle originating in ancient China that still suffers from issues like wear, contamination by debris, and misalignment.

Now, researchers at New York University have developed an innovative "fluid gear" system that removes these mechanical contact points entirely. By submerging rotors in a carefully chosen liquid, the team showed that a driven rotor can create precisely controlled fluid currents to spin a passive rotor. This setup mimics traditional gears or pulleys without any direct physical contact, using the liquid itself as invisible, wear-proof "teeth."

What makes this breakthrough especially powerful is its flexibility: unlike fixed metal gears, these fluid-based mechanisms can dynamically adjust their speed ratios and even switch rotation directions on demand. Simply by varying the gap between rotors or the flow velocity of the liquid, the system can shift from counter-rotating like classic gears to co-rotating like a belt-and-pulley drive.

This advancement promises major improvements in robotics, precision machinery, and other fields by offering a robust, jam-resistant alternative to conventional mechanical components. The research, published in Physical Review Letters, points to a future where complex machines might transmit power through flowing liquids rather than clashing metal.
