Re: Mach Effect progress

McCulloch is also talking to a consortium in California who are creating their own Horizon Drive experiment. This group includes the University of Southern California and an organization, which he is only allowed to describe as a ‘major aerospace company.’ Their goal is to demonstrate the effect “v...

Re: Mach Effect progress

I guess they could just cycle the frequency in a range. It wouldn't be very efficient, but they would get bursts of acceleration over time as the frequency repeatedly passes through the resonant frequency of the moment.

Re: Diamonds turn nuclear waste into nuclear batteries

It's not carbon-14 alone. They plan to use a blend of different isotopes to achieve different power density targets. A table was provided in their investor pack, but that's been taken offline. Some have not only shorter half lives but also generate more energetic beta particles, so even if present a...

Re: Diamonds turn nuclear waste into nuclear batteries

NASA's KRUSTY (1 kW) weighs 134 kg with a 28 kg uranium 235 core. If we apply the optimistic figure of 1.57 W/kg (100% efficiency), about 636 kg of Carbon-14 would be required for a 1 kW nuclear diamond battery. If they use isotopes with shorter half lives, they could increase power, but they lose t...

Re: Diamonds turn nuclear waste into nuclear batteries

My biggest problem with them is that there are no numbers. I am most interested in the power density. From all the back of the envelope calculations that I have seen, it might not be very good. They claim they can achieve better power density than lithium ion. Either the person who wrote the articl...

Re: Diamonds turn nuclear waste into nuclear batteries

Here's a company, Nuclear Diamond Battery (NDB), that's been working with this idea: California company NDB says its nano-diamond batteries will absolutely upend the energy equation, acting like tiny nuclear generators. They will blow any energy density comparison out of the water, lasting anywhere ...

He called it. I don't think anyone can reasonably deny the incredible left wing bias of the media anymore. And now that social media has popped up, the growing censorship of any opinion conservative.

This isn't a very high volume site to start with, but some of the foremost posters seemed to have left last year, and then the downtime from January to May put a further damper on participation (i.e. some people stopped checking in).

World-first "impossible" rotating detonation engine fires up

the rotating detonation engine is tantalizingly simple in a mechanical sense, but this self-propagating detonation wave has proven torturously difficult to achieve and sustain. Until now, it seems. A team at the University of Central Florida, working alongside the Rotating Detonation Rocket Engine ...

Here's a three-minute video presentation by their CEO, Jonathan Carling:

He says they've completed another round of funding and are very well funded going into the "end of 2019", so it's a little dated.

Re: EM Drive

The thing that started Roger Shawyer off was his observations of certain perturbations in satellite orbits. I wonder whether anyone ever came up with a plausible explanation for them.
