Instead of an airbag, why not just have your car battery
switch on a high powered magnet to release a burst of
negative magnetism? I don't think the battery would need
too ridiculous but it would have to be very powerful.
I figure the higher power the magnet the more electricity it
would draw
but to only activate it for a short burst would
not require as much energy. Impact, deceleration and other
things will initiate the
magnetism. I imagine that there would have to be some
sort
of detection mechanism so you don't send some poor biker
flying through the air.
I think one way to avoid the magnets doing too much
destruction would be to initiate a burst of negative
magnetism and then send out positive magnetism maybe
20%
of the strength to prevent sending things flying too far.
There would have to be some sort of short circuit
to prevent the car's battery from completely dying. That
way you
can drive away from the crash, assuming the magnet
worked.

//negative magnetism//
There may be a problem with this. |
|
| |
I usually find magnet ideas to be attractive. This one is
repulsive. |
|
| |
There aren't enough screwdrivers in this idea. |
|

You can package a whole-width of the car air bag, with
explosive inflation for a few of kg in weight. A massive
elctromagnet will need a significant soft iron core, a whole
massive copper coil and some fairly hefty cables and control
gear. Let's say 50 kg. Now, you're about to crash into the
back of a car, the magnet deploys, but the car in front is
made of regular steel. Now you're accelerating toward the
back of the car. So we need, coils front and back. Of every
car. |
|
| |
This is an excellent idea, apart from the bits between
"H" and "5". |
|
| |
Why not have an anti-gravity button? |
|
| |
Anti-gravity is always on, the button would be rediculouse. |
|
| |
What if you make the electromagnet out of antimatter? |
|
| |
What's needed here is not a powerful anti-magnet,
but a stupidly powerful normal magnet. Then you
have to ensure that the car in front is made of water,
or possibly frogs. |
|
| |
Magic; there's no such thing as "negative magnetism".
However, if you use alternating current, you can
(hypothetically)
induce a current in the other car, and then repel that
current's magnetic field. |

Also, [marked-for-tagline]: |

So you think ... <snigger> |

|

.... and it's not in "Other: General" ... |
|

//some sort of short circuit to prevent the car's battery

|

Seems to be some misunderstanding in the space between
//prevent// and "ensure" |
|
| |
Now now.
Clearly, Max's stupidly powerful magnet could do the trick. All cars must be fitted with one. Adjacent to the stupdily powerful magnet would be mounted a coil. |
|
| |
As the cars approach head on, the approaching magnetic field on each car induces current in the coil, producing a magnetic field which will repulse the oncoming magnet. This would work regardless of whether you installed your stupidly powerful magnet north side out or south side out which is good because otherwise pranksters would always be flipping them around on parked cars. This is in principle the same effect as moving a gold sovereign by aggressively waving a magnet on it. |
|
| |
Thinking more on this: if one wants eddy currents maybe a large flat plate would be better than a coil. |
|
| |
Thinking more this stupidly powerful magnet could serve double duty by picking up ferrous road debris, if mounted low enough. I am sure there are other things it would be good for too. |
|
| |
You can sell that on for its scrap value. There's decent weight in manhole covers. |
|
| |
" There would have to be some sort of short circuit " |
|
| |
It is spring... And the Rites of Spelling flow through the HB. |
|
| |
How much "negative magnetism" would it take to keep my electric car from hitting that wooden telephone pole over there? |
|
| |
And what kinds of "other things" would initiate the magnetism? A small child running after a ball? A deer/skunk/raccoon/redneck? Another X-Men movie? |
