Reproduction is not really a purpose. What makes copies of itself, happens to persist.

I guess the cooling alone cannot reach the density (and oxygen amount) necessary for the designed power output.

Yes, they put in the energy to compress the air 'offline' and then have that free to propel the vehicle. The cooling of the charge also improves the efficiency, the useful energy output is proportional to the temperature difference before and after the combustion.

A high capacity intercooler would be an interesting experiment also in utility vehicles.

An aluminium part with 105/72 cross section of the titanium will have the same modulus and incidentally the same weight.

Aluminium is also significantly cheaper, and easier to machine.

Titanium (or high strength steel, which is the strongest both per area and per weight and also the most expensive and difficult to machine) would be used where the volume of the part would be a concern.

> Also how they use aluminum for the connecting rods instead of stronger and stiffer metals like titanium

The 7000 aluminium alloys are similar to titanium in strenght/weight

The 10psi is still essential, saying 'it's not boost like a turbo or supercharger' is not entirely correct.

It is actually practical position for an automated swap. You drive to the position, the door on the ground open, the robot pulls the old battery and installs the new one, no hassle.

I guess the comparison to drinking a poison and having to not work, which sounds like you think that taxes are damaging. Taxes are the whip part of the monetary system, that compels everybody to work significantly more than they would otherwise, and which is behind the good things that you attribute to corporations.

Joules is the solution to both the problems (the second is that Wh for energy is as silly as speed hours for distance)
