beer cooled motor

Post by staft » May 20, 2012 10:31 am

hi,
Has anybody ever tried a beer cooling system for a motor/controller? The frame of the bike could be used as a reservoir,possibly with cooling fins radiating out from all tubes, or else a conventional radiator up front?

On second thought, I picture all the thirsty riders draining their coolant halfway through a ride...

I gotta say that's a ridiculous idea, who likes warm beer? plus if you get stopped by the police on a bike which requires water cooling since its overvolted and is already illegal the last thing you need is to be smelling like a brewery. Just a waste of beer. beer cooled biker is what you need.

:D




I think I'd rather just cool me with the beer.

Sorghum Beer is the only brew I know that is drank warmly; it ferments quickly and is not allowed to age. Created in Africa, refrigeration is not an option. I don’t think Chicha is refrigerated either.

British Beer is served at cellar temperatures, those being roughly 55*F, whereas lagers are served at their cellar temperature of origins, about 45*F. This is the chief distinction between ales and lagers. Some may argue that the class of yeasts are different; they’re not. The genus is the same (Saccharomyces), however the variety has localized. Eskimos, Auzzies, Californicators, and South Afrikaans: We’re all part of Human, it’s just that we’ve been localized.

To answer the beer-cooled motor, I was thinking perhaps using the same technology for cooling hot wort so we could pitch the yeast. Two most common methods for homebrewers are immersion chilling and external chilling. My RIMS had both and I could chill 15 gallons of just boiled wort down to 74*F in 25 minutes. The immersion chiller takes a copper coil of tubing and is immersed into the wort and has cold water pumped through to remove the heat. The external chiller is the reverse: A coil of copper tubing is immersed in an ice bath and the hot wort is pumped through.

So, for cooling a motor using beer technology would likely require the insertion of copper tubing within a hub motor (presuming we are talking hub motors) or wrapped around the outside of RC motor and having cold water pumped through. This is straight-up no-brainer thermodynamics heat transfer and fluid flow problem. If I were building a motor that required cooling, I’d likely fetch a descent radiator with two variable-speed ducted turbine fans connected to a brain that monitored the temperature of the motor in at least one point inside, and then force-pump fluid through the coils until the heat was below the selected threshold. The fans would kick in when the bike was at rest or in hot climes to assist in radiant removal. Options for the system could be that we replace the water with organic mineral oil which has a higher thermal coefficient over pressurized water and glycol. For that matter, some brewers use water and glycol to maintain temperature of their jacketed fermenters and conditioning tanks.

So it’s completely possibly to create a beer cooled motor using like technology. But HAROX nailed it (pun intended) that Iron, plain Steel, and Brass should never EVER have contact with beer due to the acidity of Carbonic Acid (CO2 in solution) which readily reacts these metals, and that which leads to create a horrible drinking experience. :P

OK, then. Hot sake, maybe? There could be a spigot mounted on the headtube. Hub nut tiny cups.Espresso sounds good, too, but all that crema gunking up the motor?
