Teach by example. Be responsible with your money and occasionally explain your behaviour. There is no age limit.

The details about economics, taxes, stocks etc are simply not relevant until late adolescent. (Besides, it is quite possible our current economic model, which is already horribly outdated, won't survive the next 20 years.)

The most important lesson about money to teach by example : never compare your wealth to that of others. Never make envious remarks about those that are more wealthy and never make degrading remarks about those with less wealth.

One rotating row and one stator row forms a stage. A traditional design with 10 stages would need 20 rows (10 rotating, 10 stationary).

A counter-rotating design with 10 stages would need just 10 rows (no stationary blades). That's a 50% reduction.

Check out wikipedia for a better understand on how axial compressors work: https://en.wikipedia.org/wiki/Axial_compressor

Is a step in a counter-rotating design equally efficient? I would guess not, since the effect of the reversing vanes decreases when they rotate.

Lets say that I build two prototypes (one with a traditional design and one with a counter-rotating design) and find that the counter-rotating design is better, what then? Where do I publish the results? Care to give some contacts? Otherwise I just spent a lot of money for nothing.

I wouldn't worry about that. There is quite a difference between some anonymous nobody who claims to have a new idea, and someone who has experimental results to show. If you perform the experiments properly, publishing should not be a problem.

Perhaps you can do a relatively cheap proof of concept with 3D printed scale models and pressurised air?

How do you get less parts and weight by replacing the stator blades by more complex and more fragile rotating blades?

What difference in purity levels are we actually talking about here? Even 99% pure Nitrogen is only a 21% difference.

Yet when someone talks about nitrogen, they don't mean air. If you do, you'll just confuse people.

Air.

Heat the tire and release the hot, moist air.

Try turning the tire around so that the valve stem is at the bottom where you can let off air pressure to extract collected water. Just TRY!

That's pretty difficult, since the value is at the inside of the tire.

- regenerative braking is not worth the bother on a bike. The potential energy gain is negligible and you need additional electronics to convert the power back so it can actually load the battery.

- There would be no issue with regenerative braking on the rear wheel. The difference between rear and front only matters during an emergency break, something regenerative braking is not suited for.

- the pedals are (nearly) in all bikes permanently connected to the rear wheel. I don't think it would qualify as a bike otherwise. Usually there is a freewheeler, but that only decouples in one direction.

- putting an alternator on pedals which are connected to the wheel is completely pointless. Adding a clutch to be able to disconnect is even sillier. It would be possible to forgo having a chain altogether by loading a battery with the pedals and discharging on the wheel, but that would be less efficient than a simple chain. Again, I don't think this would still qualify as a bike.

No band gap = no holes = no recombination. 

To get recombination in metals you need to turn them into a semi-conductor.

Besides, I already have stated that I would be discussing the existence of a higher power in a different thread when asked such.

 

Please do. If you provide examples, I, and others on this forum, will be happy to explain statistics to you.

Don't expect to fool anyone here, though; we know quite a bit about statistics.

My acceptance of a higher power does not have to based in faith. It can be based on reasoning, and also involve an observation of naturally occurring synchronicity in reality.

Here is a video describing some naturally occuring "synchronicity". It doesn't require faith. It doesn't even require trust. It's just math.

Or because we use mathematics to describe nature?

(It depends whether you are a mathematics is invented or discovered kind of person!)

The patterns and rules that cause them were present in nature long before humans existed to describe them.

Very good. The two things that do make me wonder are...

The existence of Romanesco:

And the fact that the following joke works: "Why do hackers confuse Halloween and Christmas? Because OCT 31 = DEC 25" 

There are 10 kinds of people: those that understand, and those that don't.

Did you know that if you count the number of spirals on the romanesco in different directions (or pineapple or pine cone or flower leafs or...), you get consecutive numbers of fibonnacci?

Nature is full of mathematical patterns, because it uses simple mathematical rules to achieve complex structures.

It becomes statistically less and less likely to be a coincidence as it appears more and more times in reality. Eventually, it becomes obvious that it is not a coincidence.

No, statistics predicts that stuff occurs more often in a larger group or longer Period of time.

What is wrong with the idea that consciousness is fundamental to existence?

Nothing, but this is a science forum, and nobody cares about ideas without evidence.

They can be evidence when they are all taken into consideration as a whole and not looked at as individual cases with coincidences. Once the perspective is changed in this way, patterns emerge which clearly show some sort of synchronicity to be occurring.

Off course patterns emerge, because it is statistics.

Eg statistics dictates that every group of 20-25 people roughly has a 50% chance of containing two persons with the same birthday. If you look at an entire school, about half the classes will have such a pair. You can divide the classes by year or by topic and in each category, roughly half will have such a pair. There you go: a patterns. 

Another example: people wake in the middle of the night and see 3:33 on the clock. You search the Internet and find others who saw 3:33, or perhaps 2:22, because those are not unusual times to wake up (you will never see 8:88 in the middle of the night), and some people look at the clock 10 times each night, so chances get pretty high. If we see 3:28, we're likely to still be awake by 3:33 and look again, because we like patterns. So you get a pattern of people supposedly waking at 3:33, much like you get patterns of people waking at 3:12, but nobody cares about that.

Evidence for a higher power is clear in number synchronicity. Supernatural or not, it doesn't refute the concept of a higher power.

Number synchronicity is not evidence, it is lack of understanding of statistics (which humans have a horrible intuition for), combined with our extraordinary pattern finding skills (which we have evolved to catch heaps of false positives).

I may have to buy me a set too. And I hardly ever use my die grinder...

These are properties inherited by the ant from it's parents so still these properties came  from outside the ant. You can ask, why that is the ration of antenna length to body length? Answer: It is inherited by the ant combined by environmental and developmental factors. So still outside the ant. You really can't explain why that is the property of the ant if we search the answer only on the ant

Only because the ant has an environment to influence it. A proper analogy would be the properties of things that do not necessarily have an environment, such as the universe.

I don't mean literal shapes, but ideal shapes that are possible to exist like square, triangle, circle, because there are shapes that are impossible to exist in all possible worlds like square-circle. It is really impossible obviously

While I'm no expert on topology, I would be very surprised if there are no topologies in which squares and circles do not exist; such as eg fractal geometries.

A square circle on the other hand, would exist in a spherical universe.

You have two conflicting requirements: materials which heat up fast also cool down fast. Speed of heating depends greatly on the method of heating.

You will also need to quantify: "solid", "durable", "fast" and "the same".

Accumulator heating uses stone, which could qualify for all your requirements, depending on the details.

That's a different question, would we give human rights to a computer? Who pays the energy bill? Would it be murder to switch the computer off? Etc...

It is unethical to switch off life support. The computer is required for the "survival" of this digital mind, so yes, it could be unethical to switch off the computer.
