NASA Tests Hypersonic Blackswift

dijkstra writes "Blackswift was previously rumored to be a super secret hypersonic scramjet-based aircraft co-named HTV-3X, essentially a 21st century version of the SR-71. Today NASA has unveiled the real Blackswift (video link), which uses pulse detonation engines (PDEs). A PDE is essentially a modern version of the old V-1 buzz bomb engine. This engine requires significantly fewer moving parts and achieves much higher efficiency than a turbofan, and is technically able to go hypersonic without any kind of 'dual-stage' engine."

Disappointed in people

It disappoints me to see such unintelligent conversations he at /. I remember when when the reader comments where about the topic in general and not slamming the people. Does it make you feel like a smarter person to slam someone else who does not understand the technology? Are you so bigoted that you lower yourself to making fun of people who do not have the same understanding of a particular topic? The funny thing is who are you? Are you a nobody? At least these people have good jobs and are taking care of their family, can you say the same? And after reading that last line I bet you are defensive and ticked off thinking I am implying something when all I am doing is asking a question.

It is a sad state of affairs when all we care about is belittling someone else to make ourselves look better. What is really sad is I dont care if someone is liberal or conservative, we are all people and deserve to be treated with respect, and that is definitely not being displayed here. I hope for your sake that you get treated with the respect you give to others (which does not seem to be very much).

The leadership around the world has led to this demise in our thinking and compassion. We hear all the time politicians and political figures telling us and each other how stupid they are, so we follow their lead. I think we should be better than the people that govern our lands. Just remember what Politics really is poly meaning many, and a tic is a blook sucking insect. So politics must many many blood sucking insects. Dont become one of them.

We no longer use our brains to think we use them to react and express our feelings. Logic no longer prevails. The only stupid ones are the ones that do not realize that the leaders around the world are working together to own everything you and everything you have. They find new ways to keep our eyes off the ball and what is really going on in the world today. This green movement is a perfect example, why do you think it is called "Green"? Yea right, to save the planet, bull@#$% it is because someone is making some greenbacks on this BIG time! Do some research of your own, many people involved with the "Green" movement have been selling us "environmentally unfriendly" things for years. The heads of many of the "unfriendly" companies are the ones also funding the protests and the lobbyists to force laws into place that will restrict what we can do/buy/etc. I think it is a great idea for people to use light bulbs that use less electricity. However, the new light bulbs that they are passing laws to force everyone to are ridiculous, you want to save power and money on light bulbs, switch everything to LED bulbs. The use far less power and last even longer than the "new" bulbs. And the bigger problem is why are we passing laws when at least in the US we are supposed to be FREE?

So lose your freedom go green, follow our leaders and lose your soul. Believe everything you hear and read without validating anything yourself. Watch your carbon footprint, and eventually be charged for breathing. Is there a God, we better hope not or we will all burn in hell!

Have a great day!

Have you ever read Marx? Intellectual, eh?

The Progressive era in the 20s and 30s was a hotbed of intellectualism. Oliver Wendell Holmes argued that his "starting point for an ideal for the law" would be the "co-ordinated human effort. . . to build a race." W.E.B. Du Bois was sympathetic to racial theory (his "talented tenth" was a racial term). Marcus Garvey was the man who claimed to have led "the first fascists".

"The opposition tells us we ought not to rule a people without their consent. I answer, the rule of liberty, that all just governments derive their authority from the consent of the governed, applies only to those who are capable of self-government."
Would this qualify as an intellectual statement? It was made by Sen. Beveridge, intellectual and keynote speaker at the first Progressive convention.
