Maybe you'll get iPhones to cost under $100.<br /><br />Not sure how winning the nanosat contest translates to printing liquid fueled engine nozzles. Printing sounds more applicable to solid fuel. A machine that "printed" solid fuel rockets in large quantities would be a good step.heroineworshipperhttps://www.blogger.com/profile/08441970270714146188noreply@blogger.comtag:blogger.com,1999:blog-36913768.post-48078372866164529982010-11-11T19:11:45.322-08:002010-11-11T19:11:45.322-08:00EMC^2's new facility is 1/2 mile from my offic...EMC^2's new facility is 1/2 mile from my office.

I wish LPP the best of luck in their scientific demonstration of net energy and hope they get the funding for follow on development after that success.QuantumGhttps://www.blogger.com/profile/17336493213317053535noreply@blogger.comtag:blogger.com,1999:blog-36913768.post-86735088806233879812010-11-11T15:36:01.013-08:002010-11-11T15:36:01.013-08:00For myself, I think the guys to beat is the EMC2 C...For myself, I think the guys to beat is the EMC2 Corporation with the Polywell reactor in terms of who is going to get fusion to work first, although Focus Fusion may also work. It also seem as though the Tokamak reactor is a dead end.<br /><br />Robert Bussard also did some interesting work with the Polywell designs in terms of making it into a high powered interplanetary rocket engine. If you can dig up some of those proposals, it is certainly worth reading. Then again, he also came up with the first practical (not violating basic physics) concept for interstellar propulsion based upon real systems. It would be awesome if instead of a cetrafugal artifical gravity system for a trip to Mars is replaced simply by a ship under near constant lunar-levels of acceleration or greater that is accomplished in only a few weeks instead of taking the better part of a year.<br /><br />I've suggested in the past that the potential for fusion energy to come on line is likely going to be the nail in the coffin for space solar power... except perhaps for space-based applications. When you are in space doing space manufacturing requiring a whole bunch of concentrated energy, you don't have many options available and solar power starts to look very good. If a company invested several billion dollars into a dozen power sats only to see their investment become worthless because fusion sources came on line about the same time they started to beam power down to the Earth, I'm sure there would be some very ticked off people. Merely the threat of something like that happening might be enough to keep space solar power from happening on a large scale.<br /><br />Some interesting things are happening with fusion research, and it seems like those who are playing around with different concepts that eventually something is going to stick. I keep hoping that it is sooner than later.Robert Horninghttps://www.blogger.com/profile/12496217305843430098noreply@blogger.comtag:blogger.com,1999:blog-36913768.post-9088358978989747352010-11-11T14:51:30.494-08:002010-11-11T14:51:30.494-08:00Interesting idea, Trent, but definitely not Gen-1 ...Interesting idea, Trent, but definitely not Gen-1 stuff -- they should concentrate on scaling up the physics first. If the physics won't work at scale, the capacitors don't matter.<br /><br />That said, I doubt you could daisy-chain the devices together. The fundamental problem is inductance. You need very small inductance (==fast rise times) for the trigger, and I don't know if that's compatible with the output of the MHD generator. There seems to be some research on "pulsed MHD generators" -- see <a href="http://www.google.com/search?q=mhd+generator+inductance" rel="nofollow">google</a> -- but these seem to indicate that MHD generators are very sensitive to changes in load, which is probably not good news for daisy-chaining. Decoupling input and output via an energy storage mechanism looks like a good idea.<br /><br />Capacitor banks are bulky, but I don't think they are necessarily heavy. Thinking about using LPP in flight vehicles seems to me to be pre-hatched chicken-counting though.C.

I wonder about whether the capacitor bank could be removed by feeding the electrical output of one FuFo device into the shot of another and the output of the second FuFo device back into the first. In that fashion the capacitor bank becomes necessary only for the "starter". <br /><br />The problem, of course, would be getting the timing down but the resulting weight savings would be crucial for using a device like this for propulsion - which is usually described as running liquid hydrogen through just a single device. Replacing the LH2 with something more operational (perhaps even just water) would also be a great improvement.QuantumGhttps://www.blogger.com/profile/17336493213317053535noreply@blogger.com
