Generation Definition and 363 Threads

See http://www.arxiv.org/abs/physics/0510071" excellent paper on the latest technology research on using tiny pellets of DT to yield explosions in the 100 ton range. Also includes brief but illuminating discussion of earlier nuclear weapons, from an international standpoint.

Does a device exist which can generate microwaves using heat (e.g. hot air) as a power source?

I give to you, the apple iSuck:

I recently read an article where the author stated that the momentum transferred to the air by a passing wing will eventually strike the earth, even from a high cruise altitude (in other words, out of ground effect) I have a problem with this for the following reasons, feedback would be...

I have read a number of the forums on lift generation, and I would like to add some comments for feedback. I read the forum describing lift as the centripetal force required to curve the airflow (streamlines), and I must say this makes absolute sense, I myself have always believed that...

In the Milky Way?

How can I find the rate at which heat is generated in the resister in an electric circuit connected to a 40-ohm resistor that is embedded in a .20 kg solid substance in a calorimeter. The external portion of the circuit is connected to a 60-volt power supply. I calculated the current and it is...

Can anyone tell me how dynamical mass generation works ? what is effective mass? thanks in advance matt

How does dynamical mass generation works ? In QFT-textbooks, the process of dynamical mass-generation is often used. For example one gets an effective quarkmass as a solution of the Schwinger Dysonequation. This mass is dependent on the quarks momentum.The effective quarkmass as a function of...

Hi, I am unsure which forum is most appropriate for this query but i'll start here. I am interested in building a device which works on the principle of using a stationary bike to drive an electrical generator to produce electricity, and, if practical, store it efficiently. Ultimately the...

It seems pretty much a given fact that the next generation reactors after the current nuclear fission reactors will be nuclear fusion reactors. What will be the source of energy for the next generation giga, tera and petawatt reactors? Reactors which use the strong nuclear force like a...

Regardless of our particular views on science, religion, philosophy, every one of us (I include myself) seems to be convinced of a belief which, I'm afraid, lacks any substantial support. That would be the belief that we are the first generation of humans who are not deluded about the simplest...
