F-22 is the only US airplane able to fill the air superiority role for the next 30+ years against likely foes. All the other planes mentioned have migrated more and more towards ground attack (the usual evolutionary direction as a fighter ages, with associated weight gains and increased airframe fat...

I'm an American, but I'm no longer fooled by the phony two-party paradigm. A wise teacher in elementary school taught us that the political spectrum is really a circle, with the tips of the left and the right wings touching, both wings being connected to the same turkey.

And the entire point of the F22 program was to replace the aging F15 program. No argument from me on that: http://www.avweb.com/avwebflash/news/USAF_Grounds_F15s_StructuralFailuresSuspected_196521-1.html Note the numbers; 700 F-15s to be replaced by (now) 187 F-22s. Cold war over or not, that's cra...

I like the roto-elastic aether theory of MacCullagh: http://maxwell.byu.edu/~spencerr/phys442/history.pdf "1839 - James MacCullagh invents an elastic aether in which there are no longitudinal waves. In this aether the potential energy of deformation depends only on the rotation of the volume element...

And to bring this all back on topic, the 175.5GJ it would take would also be much easier to apply by building a magnetic coil gun on the surface, driven by a Polywell fusion reactor.... Now we're getting close to Heinlein's "The Moon is a Harsh Mistress". Just a little more energy and you'd have a ...

Turning heat to electricity... efficiently

http://www.physorg.com/news177761180.html "Hagelstein says that with present systems it’s possible to efficiently convert heat into electricity, but with very little power. It’s also possible to get plenty of electrical power — what is known as high-throughput power — from a less efficient, and ther...

Re: Pentagon's DIA Issues Qualified Support of LENR

It's curious that they completely ignore the Widom and Larsen research, which attributes LENR effects to the weak, not the strong, nuclear force:

Agreed on Constellation. I despise any launcher using solid rockets. Rutan's hybrid engine approach is somewhat better, but still not a long term solution, although I'm curious to see Scaled put micro/smallsats into orbit, as they have hinted. The heat shield fiasco is just another example of short-...

On the other hand, the idea of a multipurpose vehicle that can go to orbit, while still retaining unlimited supersonic flight range in atmosphere, is very appealing... perhaps I should try to run some numbers... Please do. Given the realities of air (hopefully soon, aerospace) traffic control, airp...
