forums energies: society, ecology and clean technologies

Under this somewhat provocative title, I have had an idea in my head for a few months. At the time, I put a piece of absorbent paper in a jar of deodorant perfume and a good part of the liquid ended up coming out of the jar ... I specify that the paper does not was not soaked beforehand so it is not (that) a communicating vase phenomenon ... thereafter there was undoubtedly this phenomenon.

In short, capillarity is the possibility of raising a liquid via an absorbent solid without the addition of external mechanical energy: we can therefore speak of displacement of matter against gravity!

Obviously a fine energy is thermal, the displacement does not come from nowhere. It is the drying and the evaporation of the liquid in the absorbent body which will attract the rest of the liquid upwards!

It doesn't prevent, wouldn't there be a track to make a Capillarity motor or capillary motor? Obviously this engine would be slow and / or very large but I think that the voice must be studied. The principle would reach a little minto wheel without going entirely through a gas phase, often very energy-consuming ...

Anyone have an idea of how to start sizing calculations?

This is my contribution of the day to the safeguard of humanity ... Not sure that Greta could have had this idea!

ps: I believe that all plants use capillarity to raise their sap ... Didi67 would certainly say more on the subject!

That's right for plants.
The water rises to the leaves by capillarity.
Where the evaporation attracts the next drop at the level of the stomata.
Only. At the end of winter (except frost) the root has the strength to push the water only a meter high.
And the plants do more than that (one meter), especially the trees.
So the mechanism above a meter to the bud is mysterious.
Once the sheet is ready for the synthesized photo, it is self-maintained.
It seems that this water is the purest that can be found on earth

Well let's invent the greenhouse engine against the effect of sap! Oops no it's the opposite!

Lots of specialists leaned under it and made white cabbage

Well, we have to be better than them!



Then we work in open source to save humanity!

This will make things much easier! (the average human being so mean ...)

The Free-lance has neither a printed diploma nor a boss, but cut my Oaks to test, I will cry like Idà © fix

The international specialist is Maitre Capillotractà ©, you will have to ask him.

The force that pushes the water from the roots makes me think of the ram pump. Loss = bà © nà © fited. It is in the win-win spirit, nature often uses it.
Besides, the water which evaporates at the stomata is in pure waste, which self feeds the capillarity (in continuous flow) winning winner.
It is "pure water", which forms clouds for nature further away. And the cycle begins again

No there is no analogy possible with the ram ... well, I don't think so! But maybe microscopically ???

I can't wait to see Didier's opinion on the issue!

The ram climbs water well higher than the river with loss on the flow. Like compressed air in a water syringe (head down) with a hose pointing up
