Re: Water based propulsion for deep space efforts

The owner of the company replied to a comment attached to the article: If the specific impulse is as they say, 150 to 180, then this is completely worthless technology. Chemical rockets get a specific impulse of up to 400, I think they meant either 1500 or 15,000. GET YOUR FACTS RIGHT PEOPLE Hey CJ,...

Water based propulsion for deep space efforts

https://techcrunch.com/2018/07/21/propelling-deep-space-flight-with-a-new-fuel-source-momentus-prepares-for-liftoff/ First product has a specific impulse of 150 to 180, later products higher as the supplied power increases. The chief benefit seems to be cost. EDIT: more information on the website of...

The list of duds

Looking back over the past few years in the forum: EEStor (final death rattle) Graphenano (big promises in 2016, nothing since) Brilluion (seven years later, still no demonstration model) Cannae Drive (were going to send one into space, nothing since) QuackX (should be at the top of the list) Flywhe...

Re: Mach Effect progress

Nasa is spending billions on SLS when they could buy all the lift they needed far cheaper and have money left over. Pollywell is sitting in the corner not because it will not work; but because it's the ugly kid at the dance. its just not sexy enough. Worried about carbon in the atmosphere? offloadi...

I hope it flies, but fear there's going to be one heck of an explosion before it gets to max Q. EDIT: They did it! T...

Re: BLP news

So, roughly a year ago today: The saga of Brilliant Light Power has reached its apex. (It's culminating! It's culminating!) In a conference on October 26, Dr. Randell Mills and several industry partners presented the design and prototype of an energy generation device that is scheduled to go to fiel...

Re: Unusual Looking Space Rock

Definitely curious, but given that it's (1) tumbling, and (2) showing no sign of any sort of acceleration of its own, it's most likely a rock.

Re: Mach Effect progress

I don't believe there's enough evidence to conclusively state the effect is real, but it's disappointing that there isn't more interest from both those concerned with propulsion and those concerned purely with science.

Re: Applied Fusion Systems to build prototype reactor in 3 years

OK, I may be stupid, but what is the point of doing exactly the same thing Tokamak Energy is already doing in the UK? It seems to be that all it will do is cause funding to split between these two almost identical projects. I'm not entirely sure, but I think he's looking ahead with the assumption t...

Re: EM Drive

Just out of curiosity...is it reasonably possible that both EM Drive & Mach Thruster drive will turn out to work? Or are their "theories" of operation in some way incompatible? My understanding is that the proposed theory for the workings of the EmDrive involves rejecting wave-particl...
