Re: EM Drive

Good to hear. My predictions, for what they're worth:

1. The paper won't settle the controversy.

2. Just possibly they'll be able to report reproduction by another group in NASA.

3. Skeptics will continue to attack the experimental apparatus and the signal to noise.

Re: EM Drive

Can you quote me their claims of thrust? There are no press releases on their website with any claims that I can see. Here's something at least: http://cannae.com/cubesat/ Cannae’s thruster technology is capable of generating thrust from a few uN up through several newton thrust levels and higher l...

Re: Flywheel energy storage

Unless they show what type of material they are going to use with a proper tensional analysis at 100K RPM and 144K RPM, than this article is pure vaporware. Could it be some combination of graphite/carbon fibers and something else to provide the magnetism? Meh, I guess PowerTHRU is already doing th...

Re: Flywheel energy storage

This is commercially available technology. Flywheel UPS systems with magnetic bearings (for zero wear) have been available for years. Here is just one supplier: http://www.power-thru.com/flywheel_ups_technology.html Not for home use, yes. Probably only available at military prices. Also, the websit...

Re: Flywheel energy storage

What if you were to put the home-storage sized unit into a big, fat vat of water (large in mass and radius compared to the unit)? Would that suffice to contain the transfer of angular momentum upon failure? Water is inexpensive in many places. Could use seawater instead of fresh water in places wher...

Re: Flywheel energy storage

Levitation of a static object is unstable with just permanent magnets. Levitating a gyroscope on permanent magnets can be stable, baring parasitic forces that can be corrected with a minor force active correction system. Though it becomes a problem if the axis is tilted away from vertical. Like whi...

SpaceX seems to have a big head start though, seeing as Blue Origin has never reached orbit.

Yep. The article's words, not mine. Well, at least it means they're doing more than simulations now, which I didn't know.

Re: in the lifestyle section of the bangkok post ?

Lockheed Martin, for example, has developed a compact fusion reactor that can fit in the back of a large truck, which, according to the company's claims, can power a city of 100,000 people.


Uh, what? This has been a done deal since when? More shoddy reporting.
