The electric combustion engine

I've just come across this thread so I've only glanced over it so far and haven't had the time to take it all in. However, with regard to that last comment, why would you need a vacuum within the piston? Do you mean a vacuum within the cylinder?

 

I don't think a vacuum would be required, in fact the opposite, as I don't even think the piston would need a gas-tight seal as in a normal IC engine because any form of compression would work against the movement of the piston.

 

 

 

 

The vacuum is needed because the movement of the piston is not dependent on the movement of air coming in and out.

I still can't see why it would need to work in a vacuum. Air in the system would make no difference provided it had a free flow (such as drilling vent holes in the piston head). In this way, the piston would never be able to compress the air, negating the need to work in a vacuum.

 

(Please keep correcting me if I am wrong. I'm still trying to get my old head around this!).

When the magnet is pulling the piston towards itself it would be compressing air over and over again. When you do that in a vacuum then you don't need to deal with the air.

The point I am trying to make is that provided the air was allowed to move past, or through the piston (ie. vented), then it would equalise itself either side of he piston as it moved up and down.

 

An example: Take a bicycle pump and block the air hole. Now, when you try to squeeze the pump you can't because it's compressing the air above the piston, but if you were to pierce holes in the piston seal then the shaft of the pump would move up and down freely with no resistance.

The problem with managing the air is that you become restricted by the speed of moving the air in and out. So a vacuum should be faster in theory.

Hmm, you have a point there Simon.

 

It just shows what's involved in getting an idea up and running. It always seems to be one step forward and two steps back!

The piston crank shaft would be design in to the down position and the weight of the piston would bring it down. I don't know how much of that is even needed, if the power of the electro magnets were large enough in scale to the vehicle that it was moving then the weight of the piston would be irrelevant.

[webtrekker]

You could always arrange a series of electromagnets in a radial configuration and fire them consecutively. This might give more power in a smaller space.

 

If you make each of the cylinders an actual coil then the pistons would move within the coils, as in the simple youtube video shown above.

Instead of using micro-switches, you could have magnetic or optical sensors tracking the camshaft position and use SCR's or GTO's (gate turn-off thyristors) to use the small sensor currents to switch much larger currents through the coils.

While they sound similar to what I am suggesting they are very different.

Had a new idea the Hydro electric syphon cycle energy solution 

 

 

It uses the principle of a syphon to move the water from a hydro electric generator back in to the water source of the hydro electric generator. 

[SimonTV]

Wouldn't even need a siphon, could just create a tall thin water tank after the hydro electric dam power plant and then by gravity fill the dam back up.

I was thinking about this syphon assist hydro electric idea. If you think of this next image as a bird eye view. 

 

 

 

This is basically using the water from the river to fill the tanks up rather than relying on the flow rate of the river itself. This could be useful if they don't want to affect the flow rate of a river but they still want to generate electricity using hydro. Rain could also top up the tanks if they were open air but you would then need to clean them for leaves while if they were sealed you could get away with filtering the water at the infill which would be easier. 

 

In this tank situation the same amount of water is reused again and again and only topped by the river, this is the most efficient use of water to generate electricity.
