I agree with you mostly, but you're saying some pretty silly things, too.
You read a report saying the world has 150 years of oil. Well, five years ago I read a report saying the world had 40 years of oil left, and that in 20 years we'd already be scraping the bottom of the barrel and it would skyrocket in price. There were reports in the 1950's saying we had 50 to 80 years of oil left. Nobody knows, and there are no signs that anything drastic will happen within 100 years. People keep finding more oil, and there's totally untapped oil that people know about all over the place. On top of that, they can turn coal into an oil substitute (currently fairly expensive, but getting cheaper), and keep in mind that the US is full of coal. Wyoming is basically one big coal deposit.
The SR-71 is really advanced, but newer aircraft are obviously much more advanced in their own ways. The SR-71 is the fastest jet, but it's not going to go on precision low-level bombing runs. In that respect, the B-1 is far more advanced. A bomber guiding itself just feet above the ground at supersonic speeds -- now that's impressive. Let's look at a more environmentally-friendly definition of advanced, though. Did you know that the SR-71 requires expensive JP-7 fuel, which nothing else uses and has such a high ignition temerature you can put out a fire with it? The SR-71 uses so much fuel from takeoff (and the cold seals leaking) that it has to refuel 7 minutes after takeoff. If they wanted to build something faster, they could, but they finally figured out that there isn't much reason. Boeing and GE are mostly making more efficient versions of the same planes and engines they were 30 years ago.
Now let's think about the internal combustion engine. It's not like there haven't been any advances. This isn't a global conspiracy. There are no scientists being murdered for trying to develop a car that runs on water. Compare some cars:
1908 Ford Model T
13-21 mpg, needed oil added daily
1963 Corvette Z06
2003 Corvette Z06
Volkswagen 1-liter prototype
8.5 hp (top speed 70 mph)
Why isn't VW doing anything with this prototype they presented over a year ago? Because people don't care. There's a trade-off between mileage and power, and most people buy the car with power. Sure, they've got 70 mpg hybrids for sale, but nobody's buying. Just think about the fact that the new Corvette accelerates faster than a Viper and gets 30mpg on the highway, though. Now that's some progress.
If they could make a car run off of water, you wouldn't just pull it up to a river and fill up. You'd have to get good water, and that's almost as much as gas. And nobody would buy the thing because it would be ridiculously expensive and have no performance.
It's not that nobody could come up with something that doesn't run on gas. It's that there really aren't any legitimate signs that the world's running out of oil anytime soon, and given the last couple winters there aren't any signs of global warming, either, so most people just don't care.
It seems weird that so many people complain about pollution and using too much oil when there are plenty other legitimate environmental concerns to worry about, like deforrestation and the huge amounts of strontium 90 in random places all over the former USSR.
