Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Isn't most of that cost red tape and over the top redundancy? The technical issues haven't changed much, just the environment.

Re: EM Drive

All that, and I got the impression that it would still be at photon rocket efficiency, which at this point it's above.

Re: Diamonds turn nuclear waste into nuclear batteries

Nuclear and radiation have been demonized far too much over the past decades for this idea to see the light of day.

Re: Mach Effect progress

All of which also misses my point, to put a spaceship in your garage you at least need airliner reliability, automobile level if you want to use it a lot. While technically a thruster could be made in a garage, it would take a lot to make one with the mean time before failure as well as the thrust a...

Re: Mach Effect progress

I'll have to retract that, it makes it sound much worse than it is. If they have trouble with that though, imagine trying to do it in a garage. Point remains, to get a reasonably safe ship, you either need a lot more paperwork than I'd like to do in a garage, or a lot of work to build systems that t...

Re: Mach Effect progress

Having been in the Air Force, and in manufacturing...let me put it this way, Spacex has been QC issues, imagine what that will look like in most garage shops.

I'd love to have a spaceship in the garage, but I'd hate to have the paperwork that comes with it these days.

Re: Mach Effect progress

I would imagine devices running at far lower frequencies will happen eventually, if only by hobbyists. Once details are worked out, they should be easier to make. High school science projects should be easy, building space ships in garages less so. That's part of the excitement for some of these tec...

Re: Mach Effect progress

I think it was talked about either in this thread, or in a previous MET thread. That was also where talk of the new dielectric and why it was chosen was. I might look it up later, but as I recall they wanted something in the gigahertz range or even higher, and with a few hundred watts, apparently th...

Re: Mach Effect progress

Frequency yes, I recall they wanted an electrical engineer with a master's to design a new power supply though. Apparently they don't come off the shelf at the lower levels Woodward needs at the frequencies a better thruster would operate at.

Re: Mach Effect progress

I recall they were limited in how high they could drive both in frequency and power, both of which would boost thrust. They were also looking at capacitance materials with higher values, K I think was the letter they used. That and frequency were supposed to scale exponentially as I recall.

Re: Mach Effect progress

I don't know about em drive, but as I recall, Mach effect has a couple of orders of magnitude of improvement available from better materials, drivers, etc. That can be had.

Re: Mach Effect progress

Building a commercial device is engineering, an we've done similar engineering before. Piezo electric stuff an capacitors are known, and it will simply be a matter of time to get reliable systems.

Re: D B10 fusion?

I had a thought when I first heard of the Polywell, I'd had the thought that a civilization using it for power might use more advanced reactions as they exhaust fuels for the easier reactions. This would take larger reactors to get the well depth needed, but it would work. It sounds like there would...

Re: boostrapping a mars colony

Probably no coal on Mars to refine iron the normal way, wonder if you can get it direct with an arc furnace. Aluminum shouldn't be difficult as long as you have electricity. There is a similar process that promises other such difficult metals, I'll have to look up if they've got their pilot vanadium...
