Engine Coolant

[MrT]

Red Line Water Wetter - See demo. There is debate about this product but scientifically it makes sense.

@ Mr T - Thanks for the link - Red Line Water Wetter sounds like a product that would be good to buy and try out.


This may sound off topic, but:

@Chris - I recommended returning to the original thread on coolants, why disorganize a subject dividing ideals relating to coolant all over the site? The original thread concerns alternatives to standard glycol and water based coolants. Why not post on the original thread concerning speculation on alternate coolants. Perhaps you have confirmed the original threads subject content?

I support members of this forum posting many links and opening threads supporting their ideas, current and future success, for instance, although not an engineer and having not attended a University ( except to take a few courses in the Humanities with a high co-ed ratio ) and I do not have a degree, I began a University Student Resource thread to promote our student members ambitions and success. Not having basic knowledge of the sciences can inhibit natural creativity from developing into a technology ... wouldn't you agree?

For instance, in another thread a member remarked on the caterpillar drive mentioned in one of my favourite movies, Red October, starring Sean Connery (I 'll post about that on a movie site). There are several patents issued on the caterpillar drive. The mere mention of it started a cascade of creativity in my fertile mind.... what if you interpret it more literally, imagine 1000's of bi-metal strips, basically bi-metal caterpillars, warmed by passive solar heat, crawling across a matrix of piezo-electric film, generating kinetic energy, electro magnetic energy, wriggling faster and faster, perhaps they could activate a layer of fero-magnetic fluid beneath the film, perhaps they would generate harmonics that would somehow solidify the MR to a solid, turning it into a type of chain drive that could be harnessed by a series of levers. But I didn't for several reasons. Without knowledge in a variety of fields, my concept has no basis. I would need knowledge in many fields, materials, solid state electronics, physics, chemistry, mechanics. My fellow forum members are not reading the forum to supply me with a working knowledge, an education in these in these fields. I would be embarrassed to take up their time tutoring me in these subjects, of monopolizing the forum when there are other forums dealing with each of these subjects.

Why - I have listed on a thread and generously sent you a PM that deals specifically about innovation, conceptualization of technologies. I also put several links on the forum, for your benefit and members. One listed Innocentive - a site that links ideas to technologies, to experts in a many fields, to industry and institutions with the purpose of creating technology and commercializing it.( I thought this was generous, alturistic, while at the same time perhaps self serving to some small degree )

On Innocentive; NASA asked for a better spacesuit glove, a guy had an idea, developed it to a FUNCTIONAL PROTOTYPE ON HIS DINNING ROOM TABLE, and NASA PAID HIM.

I'll list it once again.Innocentive http://www.innocentive.com/

Goggle 'articles about Innocentive' for lots of examples every bit as inspiring and well paying as the NASA example. Just think, major corporations asking us for ideas. You don't have to be an engineer or have degrees, all they want is a working prototype or an outline of an idea to test, then you GET PAID, I didn't notice anything about F1 on it though.

Actually I would recommend reading about it to everyone.

My previous post did not refer to your conceptualization, but to the replys based on engineering and science which seemed in conflict with conceptualization.

"obviously, water is ideal here because of it's specific heat capacity"

Ginsu,

On a practical basis you are correct, but in theory I don't believe you are. In theory, the best coolant would be a liquified metal or salt, such as mercury, sodium or potassium, since they would allow the highest deltaT as the coolant passes through the circuit. While metals and salts have been successfully used as coolants in sealed exhaust valve cores, they are obviously not practical coolants for blocks/heads.

If water is your chosen coolant, you want to pressurize the coolant loop so that you can operate the coolant circuit at as high a temperature as possible without the water boiling. The primary benefit of doing this is to allow the smallest surface area possible on the heat exchanger, and thus minimize the weight and drag penalty associated with it.

Running highly pressurized, high temp water cooling circuits in engines is nothing new. The engineering principles and benefits of doing so have been known and well understood for decades. Back in the late '20's, Rolls-Royce spent a great amount of money and effort to develop a "steam cooling" system for their piston aircraft engines. They got the cooling system to work OK, but found that there were other, more practical reasons for not using coolant temps higher than about 220degF. Combustion detonation, loss of strength in aluminum block/head structures and lubricant film failure (flashing) on the cylinder walls all become limiting problems at high coolant temps.

So they put rust in the water and think it works better?

Hmmmm.
