Knowledge learned from airplane propeller development, as well as from jet plane wing aerodynamics, has had a great impact on the design of wind turbine blades, which are now affecting the evolution of birds.
If anybody ever happens upon this thread, I just want to point out, for the record, that froren is lying. He has obviously listened to and remembered this old Ron Paul speech and he understood exactly what Dr. Paul was saying, but for deceptive reasons froren choses to feign misunderstanding.
The (very clear) point of Dr. Paul's RNC speech was that regular people are better at solving problems than the government. If the government stopped taking tax money to monopolize "helping the poor" (while wasting most of that money on ever ballooning bureaucracy) then churches and other private initiatives would step in to do the job better, and at better value for the money. We wouldn't just let our sick and our poor die in the street, because unlike a faceless bureaucratic machine that inevitably comes to exists only to perpetuate itself and its own power, we are humans who care about other people.
The people at the RNC were cheering for the goodness of regular people, for the fact that Americans give more to charity than any other nation, and for the positive libertarian vision championed by Dr. Paul.
When the government gets in the way, and makes everyone poorer (by excessive taxation and bureaucracy), however, people become colder, and they can always excuse it to themselves by pointing out that the government promised to solve the problem, and they already forced us to pay them to solve it. So now it is the government's responsibility, but a bureaucracy cannot have any feelings of responsibility, because it is a machine and not a human.
This is also what happens in communist countries like China and the USSR before it.
Unfortunately, many people will probably just read deceptive statements like feoren's, and never go listen to the actual speeches. The left loves to dissuade people from actually listening to conservatives. Just see how they are shamelessly lying right now about Trump's "bloodbath", hoping to stir up actual political violence from people who they manage to trick and frighten.
The left is always trying to use 1984 style newspeak to prevent people from having an honest debate, so naturally they talk as if it was an established fact that either a government bureaucracy must continuosly rob Peter to pay Paul, or everyone starves.
This is because the left wants as big and powerful of a state apparatus as possible, because they intend to use it as an army against their political enemies. A recent example of how the left sees the role of the government is Letita James' lawfare against Donald Trump.
Ron Paul's message was that whenever the government tries to "help", it always backfires. Expecting the government to solve social problems, and allowing them to take money from regular people, leads to financial ruin for the country, and it won't even fix the very problems it claims as the reasons why we must give up our freedom and prosperity. In fact it always manages to make the problems worse.
