    Can I use thermal expansion to hold together materials?

    Okay, I will give a quick run down of what I am trying to do here. What I want to do is build a tesla turbine from old hard drive disks. Being that they're already rated for high RPM, it seems like a viable option. Now these disks are probably going to be aluminum and I am probably going to buy...

    Electrical Efficiency of Ionized Air?

    Why can't you use a coil-disk in a unipolar dynamo? I guess I am trying to think of a way to combine this concept with a tesla turbine. Where you have a magnets on either side on the outer casing of the turbine, and the copper disks inside and attached to a steel shaft. Tesla turbines are...

    Electrical Efficiency of Ionized Air?

    So basically high energy arcs with very little distance in between does what I was thinking they would? Awesome! Reading the pdf as I type this. I am not sure if I'd have to post another question I have elsewhere but I will give it a shot here first. When building a unipolar dynamo from what...

    Electrical Efficiency of Ionized Air?

    Alright so from what everyone here has told me, transferring electrical energy through an arc is just a waste? I thought that might be different because when air is charged enough it's said to behave similar to metals. If that's the case wouldn't it behave similarly to something like aluminium...

    Electrical Efficiency of Ionized Air?

    Alright It's been over a year since I've posted and received amazing help the last time I did. Now I've a question I cannot seem to find an answer to. Say you have an electrical charge and use a transformer to step up the voltage high enough to where it arcs in air. Then you have a conductive...

    Calculate pressure from vehicle moving through air

    Sorry for having taken so long to reply, but if I use a drag coefficient, that accounts for the drag in its entirety not a specific sectional area. Stagnation pressure, from what I understand applies to pressure in pipes. I guess what I'm trying to find out is the amount of drag on that single...

    Calculate pressure from vehicle moving through air

    I tried F=MA in relation to P=F/A but the vehicle isn't accelerating, its moving at a constant rate. Unless I'm confused about the definition of acceleration itself? Is there anything I'm missing?

    Calculate pressure from vehicle moving through air

    Alright, I've been looking everywhere, and tried to use a few formulas but they don't answer what I'm trying to find. Let's say I have a car that weighs 1815kg )4000 pounds) and its traveling at 90kph (roughly 56 mph) with a flat one square meter (10.76 sq ft.) grill facing the wind as it...
