I'm thinking about Tesla Model S. Let's say if we reduce the drag to 0.06 from 0.24, How far the car could run on single charge. Currently they say it runs 200 miles or so. I know they won't be able to reduce the drag so low... but this is just imaginary situation I'm thinking of.

Thank you, According to that article, if we reduce nearly half the drag, we will gain around 2.5 miles per gallon extra. I was hoping to get higher mileage advantage that that :)

I was wondering what would be the car mileage, if we reduce the current Drag coefficient from 0.30 to 0.15? Or to 0.10?

Unfortunately I don't have equipment to measure it, but I guess that would be easy to measure using the GPM / DPM filters. Or in an enclosed laboratory, that could be done. Just my thoughts. But looks like it is difficult, as it hasn't been done before.

Not conspiracy theory, but how hard is it for car manufacturer to mention the PM mass / gallon at idle running condition or at some rpm? It must be very easy to measure it, right? Also I see GPM and DPM, are they still researching on what would be the mass of it? I see the particle numbers they...

Thank you! So it looks like we don't have exact or approximate values published by Auto makers? They should mention that our vehicle emits this much particles and this much gas per gallon. That would be very useful info, but looks like they want to hide something and don't want to let us know.

Thank you. 1 gm/gallon was just thrown as example. I used various terms for search but couldn't find the formula or example for particular car model or so. I was wondering whether there is certain range for different vehicles, based on how much mileage they give.

I'd like to know that apart from Gases coming out of tailpipe of a vehicle, how much is Solid particle mass exhausted per gallon of fuel? I tried to search but I couldn't get exact answer. e.g. After 1 gallon of fuel burnout, exhaust pipe emits 1 gm or 10 gm or 100 gm of solid particles (PM10...

Well for the machine shown in video, these gears are in back side of the machine. One gear is driven by motor and that in turn rotates all gears in clock-anti clockwise fashion alternately, which touch each other. I'll have to calculate the resulting load of all these gears on the driving one...

Thank you, that was good one. Can I use the mold to make plastic gear or is there any other technique to create a gear? Like metal gears are made on machine?

1] I guess the load is just to rotate the gear, which initially have mass resistance of 4-5 lb, I guess. Not more than that. I don't see any other load coming in except the tension of the rope/thread from the bobbin. 2] Little difficult for me. Will have to ask an engineer. But considering...

Here is what I'm trying to prototype using plastic gears and other components.

Hello, I wonder whether I can replace the Metal gears and other parts with Plastic material? If so, what kind of plastic material should I use? There is no heat and the force is also not that great but the speed is. This is not for toy but industrial machinery, with gear diameter of about 10...

I'm also curious about the cause(s) of Heat in conductors? Is it because of Back EMF or Just Current drawn? or something else? Virtually, What can be done to avoid the heating of conductors?

That means Electromagnets... so we need electricity to generate electricity. I know Neo Magnets have flux upto 14 KGs. What is the max Flux value we get from Electromagnets?
