mjan22640··on Why Everything in the Universe Turns More Complex
Reproduction is not really a purpose. What makes copies of itself, happens to persist.
mjan22640··on Drag racers are ditching superchargers for scuba-style tanks and compressed air
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.

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)

Entropy is the opposite of potential.

Rabies virus induces the same behavior across different species (the victims in terminal state are terrified by swallowing liquids).
mjan22640··on Mitochondria Are Alive
The benefit of mitochondria is in the isolation of the high power reactions, that involve chemically aggressive elements, from the rest of the cell. That allows for high energy throughput without self damage. Cells that do not have mitochondria run the same or analogous power producing reactions, but at a much lower volume, to keep the damage sustainable. An alternative option to mitochondria would be to evolve some means for isolation of the power production.

> Laws are generally clearer if you write them as general definitions and general rules and if those cover too much carve out exceptions in the rules rather than the definitions.

Similar motivation as exceptions for error handling

mjan22640··on Buy, Borrow, Die – Explained
At the start of the circuit the government prints and spends money, at the end it collects the money as taxes. This creates a current of economic activity. The duty to pay tax is the primary incentive that stimulates the citizens to put in effort and gets this into motion. The proper action is not to try to pay less taxes, but to put in more effort and make the money to pay the taxes.

It is actually the opposite. It all belongs to the rulers, and they generously gift you a portion of it.
