With enough electrical know how, would it be possible to electrify the exterior of a car to levels that could incapacitate or kill a very large animal? Also, what sort of power supply would be required? Would a bunch of car batteries connected together do the trick? Asking for a friend.

Something like the robocop 2 car defense thing? https://www.youtube.com/watch?v=bMtqRir7dco

This feels almost Puckin-like. We uh We don't have anything to worry about here, do we?

The most illegal? Also yes. Pretty sure that qualifies as a booby trap which is extremely not a good look; if something happens and a human gets caught in your bear-shocker, and dies, you are very likely to be charged with murder. There is no use case which makes this a good idea.

So what... is the OP going to start the Edison car company?

I'm getting the impression that anyone asking this will kill themselves like that guy who decided to 'hack' a streetlight.

Thanks everyone! Way more helpful than the post in the science thread! I'm writing a speculative fiction story. Never gonna try it. I just had to know if it was possible! If "electrical know how" didn't give it away I dont know much about electricity or cars or science. Thanks again!

How about flames instead? https://www.youtube.com/watch?v=aLhWzMOccTg Could you really get this to work? Does automotive paint conduct electricity? Would you need to use a delorean instead of a normal car?

I feel that there is an optimum level of electrical know-how to achieve this aim, and further know-how beyond that admittedly low bar will be more of a hinderance than anything else.

Well for it to work the way that you mean, the system would have to generate potential to ground so that the body of the "animal" would complete the circuit much like touching a power line. One problem with that is, I don't think tires are great insulators what with being fully impregnated with steel belts and not designed for that at all. Secondly, the electrical generation would have to be grounded itself somehow or else you don't have a circuit. That's really difficult to do with a vehicle that isn't stationary. What you could do however, is cover the exterior of the vehicle with small areas of potential difference that are isolated from the structure. Think like, defibrillator pads. The subject would have to touch two at the same time to complete the circuit, but they could be spaced such that experiencing potential difference is almost assured by the subject. The system could also operate at a relatively lower voltage as it would not have to overcome nearly as much impedance to achieve the desired result. angryrobots fucked around with this message at 03:06 on Jul 26, 2018 |

I wonder how well it would work to drag a ground strap, like those buses that have a dangling chain underneath to keep static from accumulating.

Yes: https://www.youtube.com/watch?v=rTGn76YljUM&t=610s You can have single points on your car that are positive and when you touch them, you form a circuit to ground with your body. You can't do this with the entire car body as modern cars are designed so that the entire body/chassis is connected to the negative terminal of the battery and acts as a ground. https://www.quora.com/How-many-AA-batteries-would-it-take-to-electrocute-someone This articles suggests that you could kill someone with 220 AA batteries - I am sure that li-on batteries could do the same and would fit in a shoebox.

It's not voltage that kills it's amperage. https://www.physics.ohio-state.edu/~p616/safety/fatal_current.html

spog posted:Yes: I don't think that's how this works. There are two visible strips behind the electrified door handle. I would bet they are mounted on an insulator, and you complete the circuit by touching both of them. "All electricity is trying to get to ground" is an awful  saying.

This video is ancient, but here you go. https://www.youtube.com/watch?v=9nRqbQr7VGk You can probably electrify the skin of the car using a similar tesla coil inside the vehicle, faraday caging the occupants and using an earth ground. Voltage limitations are present with the smallest charged air gap (the wheel to ground) so you probably have a max theoretical voltage of 75kV or so. Skin has a resistance around 100kohm, so you have a max theoretical current of 750mA. Across the heart, this gives you up to 5% chance of cardiac fibrillation. So regardless of how much power you could drive, it's extremely unlikely do do anything lethal, but I can promise you it would hurt like hell. I know my answer was supposed to be a joke answer but I was curious.

Lifted suspension and fitting tires with high sidewalls will help increase that minimum airgap distance to get you up to lethal
