Conducting Electricity: No Wire Transfers?

In summary: It's called "static" because there is no current. A good way to produce electrical current is to use a conductor, like metal or plastic, and apply an electric field to it.

Is it possible to make electricity travel between 2 places with no wires?

Of course

It's called a TV.

If your definition is the movement of charge , then TV's fire electrons at the screen , high energy accellerators fire electrons and or protons around all the time. Electricity in fluids ( without literal wires) is carried by charged ions .

lightning. whoosh!

once you build up a great enough potential difference... most anything can conduct

can we send satellites to space that get electricity from sun and transmit it to earth?

In wires, the EM fields that propagate at near light speed carry the energy; the electrons move (drift) slowly. A satellite collects the solar energy and converts it to microwaves (EM fields). The microwave radiation (think microwave oven) is transmitted to Earth (just like a radio broadcast), captured by a ground antenna and transformed to usable electricity.

A BOLT OF LIGHTENING...

Talking about lightning, is it possible for human to simulate lightining in order to generate electricity?

Wont this reduce pollution. We could send energy satellites to space send electricity to Earth and use it. The pollution due to thremal power plants can be reduced.

One of the issues with transmitting a microwave beam back to Earth from space is that the energy density of the beams would be quite large this would make it deadly to any bird or plane that passed through it. You would have to have some way of preventing such events.

I have ofter pondered the possibility of huge moon based photoelectic farms beaming energy back to earth.

Is it possible like for eg, that a country launches a satellite for electricity. Is it possible for the beam to accidentally unfortunately hit its neighbouring enemy country?

Ha ha, of course! But what would it do? Other than kill stuff? Knock out electricity too?

Other-than-lighting-ways:

Spark gaps, http://www.voltnet.com/ladder/index.shtml , toroids, and tesla coisl (or http://www.voltnet.com/tesla/index.shtmland ) use air as a conductor to work.

Also, there is something that may be relevant to this, it is called splitting an electron, you can spatially separate an electron's charge and mass I believe.

Reminds me of SimCity, when the microwave beam misses its power station's receiver. Things go ka-boom. :)

Static electricity (lightning, cosmic particles, etc.) is not a good way of producing electrical current.
 

1. What is meant by "Conducting Electricity: No Wire Transfers"?

Conducting Electricity: No Wire Transfers refers to the ability of electricity to flow through a material without the need for physical wires or conductors. This is achieved through wireless technologies such as induction, resonance, and microwaves.

2. How does electricity conduct without wires?

Electricity can conduct without wires through several methods, including induction, resonance, and microwaves. Induction involves creating an electromagnetic field which can transfer electricity between two objects without physical contact. Resonance uses similar principles, but with a specific frequency to maximize the transfer of energy. Microwaves use high-frequency radio waves to transmit electricity over long distances.

3. What are the advantages of conducting electricity without wires?

Conducting electricity without wires has several advantages, including increased safety, convenience, and efficiency. Without the need for physical wires, there is less risk of electrocution or fire hazards. It also allows for more flexible and convenient use of electronic devices, as they do not need to be physically connected to a power source. Additionally, wireless electricity transfer can be more energy-efficient compared to traditional wired methods.

4. Are there any drawbacks or limitations to conducting electricity without wires?

One of the main limitations of conducting electricity without wires is the distance over which it can be transferred. Induction and resonance methods have a limited range, and microwaves can be affected by obstacles and environmental factors. Additionally, wireless electricity transfer can be less efficient and may result in energy loss compared to wired methods.

5. What are some real-world applications of conducting electricity without wires?

Wireless electricity transfer has several practical applications, including wireless charging of electronic devices, powering electric vehicles, and powering remote sensors and devices. It is also being explored as a potential solution for transmitting electricity over long distances, such as in space or in remote areas without access to power grids.
