Cant we run a generator with the electricity generated by itself?

Answer 1

all conversions of energy involve a portion of the initial energy being "wasted" as heat or entropy.

this is known as the second law of thermodynamics and is universally accepted and never challenged. It is a cornerstone of physics.

because of this wasted energy, no conversion of energy is ever 100 % efficient. Because of this, the output of a generator ( a type of energy converter ) can never power itself indefinetly.

To date, there have been NO observed violations of the second law.

hope your question was answered :)

Answer 2

No. If we could, we'd have a perpetual motion machine, which is a physical impossibility because of mechanical (and in this case electrical) inefficiencies. Inefficiencies simply say that the amount of energy we get out of a machine or tool has to be less than what we put into it. Tools and machines just change one kind of energy into another kind, but they do not create energy.

Your generator, for example, converts mechanical energy into electrical energy. An electric motor converts electrical energy into mechanical energy. But in each case, due to inefficiencies, the amount of energy taken out is less than the amount put into the system.

Inefficiencies come from many sources, but the main one is friction. As things move over surfaces, friction creates heat and that heat subtracts from the energy output. So, in equation format: O = I - H; output equals input minus heat energies. There are other inefficiencies, but you can see where this is going.

Answer 3

you have an interest in a dynamotor. that is a unit containing a motor and a generator. Many military radios from international warfare 2 used 12 volt skill from vehicles and used a dynamotor to generate 250 volts to activate the vacuum tubes. You look interested in creating 33,000 volts from one thousand volts at 5,000 watts. this can artwork, besides the undeniable fact that the most present day you're able to draw from it can be 5/33 , that is 0.151515 Amps at 33,000 volts if it were 100% effective. As all and distinctive else referred to you could't get more effective acceptable than 100% performance, and in practice dynamotors were more effective like 30% so the optimal present day you're able to get could be about a million/20 amp. do no longer try it without professional help because 33,000 volts will bounce about 2 inches by ability of air and a million/20 amp is more effective than adequate to kill someone.

Answer 4

No, because the generator does not generate enough electricity to power itself. This is a type of perpetual motion machine and all such machines violate conservation of energy.

Answer 5

Not really, but there is such a thing as free unlimited energy from the vacuum. There are batteries can will keep building up a charge, forever. Look up the work of "Tom Bearden" (www.cheniere.org) and another good one is John Hutchison. Tesla was the one who originally pioneered free unlimited energy, however the concept is pushed out of mainstream knowledge by the corporations who profit from a market of scarcity. Alot of physicists will deny that this is possible - they need to search deeper and open their minds and models.

Answer 6

No, because a generator requires power to turn, and that power is greater than the power it generates (i.e. the efficiency is less than 100%, around 90% to be precise, for the best generators that could be obtained).

Answer 7

You will notice that a generator also generates heat (through friction of its components). Creating that heat requires energy.

Answer 8

there are many ideas that border that very thing...and a good idea it is..but on the outskirts of cutting edge technology where the common people are[us] perpetual motion has not been conquered yet...there are many hybridized machinations that border that, but not quite yet have they perfected it...

you know if it was, the industrial bigwigs would never let it see daylight, don't you??? there is too much money to be lost by the big industries to let that cat out... ; }

Answer 9

No, perpetual motion is impossible outside a vacuum. Only Alan Greenspan is that efficient.

Answer 10

If it were 100% efficient, then yes. But since that's not likely, the energy dissipates.
