Almost Frictionless Gears With Liquid Crystal Lubricants

Lubricants in bearings and gear units ensure that not too much energy
is lost through friction. Yet it still takes a certain percentage of
the energy to compensate for friction losses. Lubricants made of
liquid crystals could reduce friction to almost zero.

With these Lubricants we may see more efficient cars and bykes. And
also it will boost all Machines used in Production. Saving lots of
energy. And Transportation costs will go down.

I think it will take atleast 4-5 years to commercialise.

> Lubricants in bearings and gear units ensure that not too much energy




Most bearings, gears, pistons/cylinders and other wear surfaces are
designed so that fricition with conventional lubricants is < 5% output
so there isn't much room for improvement as far as directly saving
energy in conventional machinery is concerned.

If wind resistance is a factor then the advantage would be even less.

The only way to get real energy savings from a super lubricant is that
it could result in so much less wear than conventional lubricants that
previously impractical designs, i. e., lighter gears made of softer
materials, could suddenly become attractive.

When teflon was invented it was supposed to give us near frictionless
bearings.

Then it was discovered that it would flow under a load.

Glaringly lacking in all the breathless announcements of liquid crystal
lubes is any mention of load and temperature range.

If you read complete article you will get the details. Yes, It works
on high load. Not sure about temperature.

another factor is cost. if it's too expensive to manufacture, it would
be more worthwhile to go with the older but cheaper lubricants.

No, you won't.

The article you referenced is a rip from a Fraunhofer-Gesellschaft
press release with zero useful details.

Investigations into the lubricating properties of liquid crystal
materials goes back to at least 1994.
