So lets get back to the basics in electricity. As everyone knows, electric current is just a flow of charged particles, so there is nothing special about it. But what about the type of particles and the differences of produced currents?
To make things simple let's take a look at 2 basic charged particles - protons and electrons. They have the same charge, but with the opposite sign. Also electron weights about 2000 times less compared to proton.
As far as I understand, in electric appliances we use only electron currents. They originate as flow of electrons in the crystallic structures of atoms in conductors between protons (just like Dirac's concept, it is an ocean of electrons). But what happens if we choose protons as a charge carrier?
Since it is much heavier with the same charge, its current flow will produce much more work - just about proportionally to the weight ratio.
And also it is quite ineffective to use light electrons in heating elements and mechanical appliances like electric motors or transport devices (cars, scooters, planes, helicopters and drones).
So my guess is that electrons currents are good at communications with low losses. But when it comes to heavy work or heating, protons currents are about 2000 times more effective as much more massive particles.
So the question is - why aren't we still using proton currents - are there some technical difficulties about generating or transporting it?
Also is it possible to generate the opposite flows of particles with the same charge value, but much differences in weights?
That would allow us to create devices to get 2000 times increasing force just by generating small amounts of electrons with no problems with energy conservation laws.
