Chunk in the Trunk!

chocolate chunk, that is.

Wouldn't it be neat if you had a car, but instead of a trunk, it had an ice cream maker. And you could just put in the ingredients as you begin your trip, and the kinetic energy from the vehicle would rotate the tumbler, and by the time you arrived at your destination, you'd have a trunkful of ice creamy goodness!

Yeah, that'd be neat.

Making ice cream http://www.amazon.c...0?v=glance&n=284507
This is how they did it, before cars. [nihilo, Jun 19 2006]

       In retrospect, it may make more sense to have an ice cream maker on your bike. So you pedal and make ice cream. You burn fat calories, and then you eat frozen ones.

       Why not? In the book "Travels with Charlie", (his poodle) by John Steinbeck, the author set up a bungee cord bucket to wash his clothes. The constant jostling was like the agitator to a washing machine, and it worked. Same thing here.

       I don't think it would need to take up the entire trunk (unless you're having a very larege ice cream eating event).

       good ole Dr Nick.   

       Oh yeah, I like ice cream. I like cars. I like this idea.

       Of my 26 ideas thus far, only 4 pertain to food -- and that includes "Gourmet Man Milk", which is a bit of a stretch ... in more ways than one.   

       That amounts to about 15.4%, which, the reader will note, is conspicuously less than "all".   

       Admittedly I did have two of those food ideas today. So maybe I skipped lunch. And maybe I like junk food.
In prodigious quantities.
In lieu of *actual* food.
Maybe.

       Aw, I can teach you to count, Bubby. All you had to do was ask.

       Oh, sit down, both of you... most people are here to read about ideas - and I quite like this one, unusual though it is - not to come across "who's got the biggest ego" contests.

       Besides, there's no contest as long as I'm here. I wish there was a way to capitalize the 'I' even more to signify my greatness.

       The ice cream maker needs to conserve the vehicle's kinetic energy [read: more complicated]. Automobiles already waste too much energy. Ice cream makers need some sort of rotating/agitated container which the ingredients will be placed.   

       A solenoid will engage a clutch connecting the container's eccentric drive shaft to the vehicle's rear wheels or axle (depending on application). The solenoid will be governed by a microcontroller.   

       The microcontroller will know how long the ingredients have been agitated, and it will know when the vehicle's brake lamps are illuminated (this wiring already exists in the rear of the car). When the vehicle operator depresses the brake switch, the clutch will engage, the assembly will spin until the microcontroller shuts off power when sufficient agitation has occurred to create ice cream. At the same time, the mass of the rotating container will provide a tiny bit of help decelerating the vehicle.   

       One downside is highway trips...if the braking system isn't used the container will not spin, and no ice cream will be created. For this, a dash mounted switch could be used.   

       The second downside is that the vehicle must be in motion while braking, meaning you could not park the car and make ice cream. A hand crank would be a decidedly low-tech fix for this issue. Or the user could drive back and forth, slowly engaging the brake to come to each stop.

       Instead of motors in wheels, maybe ice cream makers in wheels? Some sort of slip ring arrangement to get electrical current to a heat pump for freezing, and the rotation and suspension bounce will agitate the icecream perfectly.

       By the way, [david_scothern] has 24. Me? just 2.

       I think 59 is a respectable number.

       Hey, that ice cream bucket on the first link used to be made in the town I live in! (sadly most of the woodshops have left town and gone south) .....and besides that, it's about was about 200 degrees in my trunk the other day, so I think that's a bit hot for making ice cream, but I do like david_scothern's idea of making it in the wheels.
xandram, Jun 21 2006
  

       I believe they make 12V electric ice cream makers, with the bucket that you freeze before using. Just install a lighter socket in the trunk (boot). Granted, it's using electricity from the alternator, not using the car's kinetic energy, but probably would affect overall efficiency less than a pure mechanical arrangement (not to mention a LOT cheaper to retrofit).
