When I reach to twiddle the temperature control knob on my car's thermostat, I get confused. I can't remember if the red or blue color code means hotter or cooler. Why? Because everyone who has studied thermodynamics knows that cooler objects emit redder light and hotter objects emit bluer light. Yet
the code in the typical car has it exactly backwards! (Designers seem to associate red with fire and blue with ice water - silly if you ask me.)
Solution: A full spectrum thermodynamically correct color code on the control knob. Blue is hottest, red coolest, other colors in between in correct order.

Do you mind if I slip in and swap the coloured knobs
on your shower taps, while you're not looking? |
|

Thats exactly how I 'repaired' the kids shower last month. I crawled under the house to see why there wasn't any hot water and couldn't see anyway there could be a problem. The wife was going to call a plumber (ie someone who knows what they're doing), when I went to the shower and put the knobs back on the right way 'round. |

How about running resistor wires through the knob or lever? As you experiment moving it to the left or right the knob gets instantly hotter or colder to your fingers. |
|
| |
I don't think the idea, as written, is of much use to
the 10% of males who are colourblind. |
|
| |
Perhaps some different colors would be better, because you are trying to overturn Tradition. |
|
| |
So, how about green for cool and fluorescent violet for hot? Thermodynamically, violet is hotter than green, and people tend to associate green with coolness, about as much as they associate blue with it. |

I am eternally thankful that the engineers who build cars
have the common sense and restraint to not build cars
_for_ engineers. |
|

Oh, do shut up. You actually imagine that a Series IIA
Land-Rover station wagon is a car, don't you? |
|
| |
Certainly not; it is far superior to a mere
car… |
|
| |
// slip in and swap the coloured knobs // are you talking
about my bundy pants again? |
|
| |
This could be expanded so that, for example,a car has all
instruments and controls in some sort of Physics
representation.i.e. SI units, increasing average wavelength,
probability distribution. |
|
| |
Mate, I'm trying not to even *think* about your Pervy
Intrapersonal Hanky-panky Panties. |
|

//all instruments and controls in some sort of Physics representation.i.e. SI units// |
|
| |
I actually prefer the American system of units: e.g., for speed, 'furlongs per fortnight,' etc. |

Howabout some ISO pictures of 'fire' and 'ice?' |
|
| |
Pshh, cars with knobs? Most cars have buttons that let you
tune the temperature to the degree. |
|
| |
// Howabout some ISO pictures of 'fire' and 'ice?' // |
|
| |
I've seen some with a little pictogram of a flame on the
right and a snowflake on the left. Can't remember what
make, though. Volvo, maybe? |
|
| |
Just for fun, I am sure there's an Over-Engineer somewhere who programmed the control so that the snowflake represented "I feel cold". |
|
| |
// Howabout some ISO pictures of 'fire' and 'ice?' //
I've certainly seen them - possibly in a VW circa 1982? |

Thermodynamically correct? |
|
| |
Let's see: PV=nRT, that's pressure times volume equals number of moles of gas, times the gas constant, times the thermodynamic temperature. The thermostat doesn't change your house's volume or atmospheric pressure, so you could combine all that with the gas constant, (PV)/R=nT. So it would be perfectly valid to set up the thermostat to dial up/down the amount of air molecules in the house. |
|
| |
//the amount of air molecules in the house// |
|
| |
You will need to compensate for changes in atmospheric pressure. |

Sounds like something from "Blast From The Past",
starring Brendan Fraser as an anachronistically inept
time traveller... again. |

This is a super idea. If I weren't renting this place I would swap my taps at once. |

You RENT the HB, [pocmloc]? Holy cow! How the
other half lives, eh? |
