Research Team Sees Water as a Replacement Form of Lubricant

Hmmmmm.

Didn't mineral oil replace water as this lubrication?

Can you paint doors with it?

Dunno, but I'm willing to give it a try!

Soooo, water + some readily-available biopolymer = mineral oil replacement.

Got to give them credit for what is effectively repackaging......water.

It's called "Water soluble coolant"

And there are many companies making it!

I've been using it to cut metal for more than 20 years, and I''m sure there are some out there who have used it for even longer.

Water, oil, soaps etc. have different lubricating a and cooling properties. The dim bulbs wise researchers in germany may say whatever, but it does not affect the properties of the liquids. The quantities involved in metal turning? Get lost and stay lost with this inane proposal.

Have a closer look at the article and the product ranges offered as it isn't as bad as you think, and in some cases may be better than just plain filtering and recycling used mineral oil lubricant (which you should all be doing anyway).

Would that be tap water or a special water, like Dasani?

Recycling is the sane, standard way of using lubricants. Preventing of oxidisation is one of the main purpose. A year or two ago, the city of Los Angeles prevented the use of hydrocarbons in machining. The same tinpot twits had no say in shipping and freight use of the same hydrocarbons. So, let me see, no control of millions of gallons, control of single gallons. Yeah, the way of the tinpots.
