Discussion Overview

The discussion revolves around the necessity of wires in tasers for delivering electrical shocks to targets. Participants explore the implications of using wires versus potential wireless alternatives, examining the underlying physics and engineering challenges involved.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question why wires are necessary for tasers, suggesting that stronger electrical currents might be needed without them.
  • Others draw parallels between tasers and household electrical systems, prompting inquiries about the fundamental role of wires in conducting electricity.
  • A participant proposes the idea of a taser that could ionize air to create a "lightning-like" effect, raising questions about the feasibility of such a device.
  • One participant explains that ionizing air requires a very strong electric field, which is difficult to achieve with a handheld device, and discusses the implications of creating uncontrolled ionization paths.
  • Another participant highlights the potential hazards of a wireless taser, emphasizing the risks to the operator.
  • There is a clarification that a taser requires two wires for a complete circuit, countering the notion that current could return through the ground or the operator's body.

Areas of Agreement / Disagreement

Participants express various viewpoints on the necessity of wires in tasers, with some agreeing on the challenges of creating a wireless alternative while others propose different concepts. The discussion remains unresolved regarding the feasibility and safety of potential wireless taser designs.

Contextual Notes

Participants reference the need for ionization and the challenges of generating strong electric fields, but do not provide specific mathematical details or assumptions underlying their claims.

Why does a wire is needed for carrying the electrical current down the target in tasers?

Perhaps without the wire the elecrical current needs to be much more strong?

Why don't construct some kind of wireless taser that uses ultra-super-strong-electromagnetic pulse (which would make it as efficient as a conventional taser)?

Why is a wire needed to carry current in your house? Or anywhere?

Because (in the case you mentioned) electric current consists of so called free electrons that make up the wire.

I wanted to ask if there is a way of constructing a taser so strong that the electrons are pulled into the air on their way to the target, i.e. a lightning like taser.
 
I;m sorry, I thought you wanted to learn about how real circuits work. Carry on.
 
In order to efficiently conduct an electrical current, the air would need to be ionized. In order to ionize the air, a VERY strong electric field is needed. Generating such a strong electric field over several feet is very difficult to do with a hand-held, battery operated device. In addition, this field would create ionization paths in randomly generated directions, much like how lightning is formed. This ionized path of plasma would easily conduct current, but the current would need to be high enough to keep the ionization path intact for the duration of the shock. The amount of current would be far more lethal than current tasers are. It would be impossible to control, almost impossible to generate, and entirely useless as a less-lethal device.

Not to mention a hazard to the taser operator !

You do realize that it takes two wires, right? The current does not return through the ground, the operators shoes and his unwitting body.

Oh, yes. It should be a closed circuit taser-target-taser.
