       +, though I do see a problem, involving a thief with a small tank of carbon monoxide.
—Worldgineer, Jan 02 2004
   

       interesting challenge, though the sensors are on the inside and the thief is on the outside.   

       Occurs to me that we can actually put the sensor in the car itself and cut off the engine.

       //inside...outside// But most garages have cracks or leaks somewhere, and it wouldn't be a big trick to be able to get a small tube under a door.   

       I like the car idea even better.

       "Monoxide" is good: "It has been demonstrated that O1, a beneficial free radical, will kill bacteria, viruses, fungus and molds by attaching to them and oxidizing and eliminating them. These lower life form organisms are mostly anaerobic. 'Anaerobic' means they can't live around activated oxygen."

       And also the issue, of 'Who needs a large tank of CO, anyway?'   

       Is there a purpose for having pure Carbon Monoxide in a canister, anyway?

       Does it spread well on toast?
—motive power, Jan 02 2004
   

       Undoubtedly.
—Baker^-1, Jan 02 2004
   

       I disagree with auto-opening garage doors.   

       It should instead activate a ventilation system of some sort - even if it's just a wall vent. Thus, it could be used in locations other than garages. CO build-up can occur inside the house too, from furnace problems, blocked flue, etc.
—waugsqueke, Jan 02 2004
   

       [Gromit] - You're right. I forgot about that.   

       And 'borrowing' a can of calibration gas from an auto shop shouldn't be a problem, especially as an inside job. An important concern.

       To keep people from commiting suicide?
—ariha, Jan 03 2004
   

       The automatic ventilation and alarming of carparks is widely baked in commercial properties. The usual numbers are something like 500ppm to enable extra ventilation and a warning alarm just above that (I'll check some technical specifications later).
Sensors typically cost £200 - £1000 depending on sophistication. Many provide a volt free relay that can interlock with a ventilation fan without the need for the further expense of some form of DDC control system.
I would favour [waugs] solution but would doubt that many people would run a car for long with their garage door shut, apart from the suicide thing when they could bypass any safety overrides anyway.
—gnomethang, Jan 03 2004
   

       If it's to stop people from committing suicide it is easly beaten.Just drive to any open space,run a hose from the tailpipe to a partially open window, tape closed the gap and start the engine. Problem solved.
—python, Jan 03 2004
   

       ill take that one
—Space-Pope, Jan 03 2004
   

       Obviously anyone committing suicide would simply destroy or tamper with the sensor, but it could prevent accidental deaths. [+]

       The sensor-fan idea is tops.
—RayfordSteele, May 14 2018
   

       To find out if my engine is on would simply be a matter of measuring the amount of "What ?" "Say that again", etc. interjections that occur in occupants' conversation.
—FlyingToaster, May 15 2018
   

       Just read an article about this. Accidental deaths in the age of remote starters is becoming a real issue. (Oh, I see TC has put up a link.)
