If you check out the technical PDFs referenced from Reaction Engines' site, you'll get an idea of how much reaction mass 'air breathing' saves. http://www.reactionengines.co.uk/ IIRC, they also realised that it may be better to carry extra hydrogen as coolant and burn it *inefficiently* than to carr...

http://www.kennethsnelson.net/circ_sph/index.htm I was looking for something utterly unrelated to polywells etc (*) when I stumbled across this site. All I can say is the geometry is pretty, and some of the configurations seem to match the different generations of whiffleballs... Fun, too !! --- (*)...

Sure is blue-ish when pressure and voltage suit, but I hope he's taking precautions against the UV... Um, not in 20A league, but I changed and aligned a lot of spectrophotometer deuterium lamps... Slightly OT: For a while, the *very best* deuterium lamps were hand-made by an elderly craftsman in Kob...

Sure be worth a try once a round' one can be got working... Um, as I see it, there may be uses to extending the 'hot-spot', one being a gradual extension to linear, to rocket engine or plasma source. These notions hanker back to the original fusion experiments with toroidal or figure-8 configuration...

Would ther be any advantage in grafting this approach onto something like the SABRE core from Reaction Engines ??

Solves the problem of trying to get additional energy into a hot-shocked hypersonic flow...

Perhaps relevant to the proposed scheme is our experience of a HV & Water utility renewal scheme... Contractors dug a trench approx four feet wide and nine deep along a quarter mile of busy road. Okay, it was fun watching the new pipe-sections being butt-welded, the cable's mega-bobbin being unrolle...

How does graphene stack up against silver for electrical conductivity, or mono-isotopic diamond for heat ??

Okay, I'm being a tad facetious here, as one is outrageously expensive in industrial quantities, and the other requires nano-g orbital industry...

Um, justifying some really fancy 'controlled fusion' tech by claiming it would help learn to set off a fission bomb's explosive charges strikes me as 'tight-rope walking'... Certainly lets them play with real-neat toys and Ooh-Shiny stuff, gives them some lovely buzz-words to put in their annual rep...

Several years ago, I was walking past a local hair-dressing salon when one of the customers came out with a cell-phone to her ear and several yards of alu foil portions tied into her hair.

The reception did not appear impaired...

"Extraordinary claims require extraordinary evidence" Sadly, too often, they do. They must cut through a heap of pre-existing opinions and interpretations, literally change the paradigm... Um, couple of examples across several fields... Continental Drift / Plate Tectonics. Idea was around for a long...

Remember those neat kitchen hobs that work by induction ? A down-side of transmitted power would be accidental pick-up. Like fragments of foil or gold trimmed plates in your microwave... Nearest we have today beyond the locale of eg BBC World MW & LW transmitters is that US ELF system which apparent...

Trick is to have just enough 'fuzzy' light to remove concealment but maintain some night-vision.

Floodlights create enough deep, dark shadows to hide a football team...

Our neighbour took down her motion-sensor flood-lights overlooking garage roof because local cats would go there to bask...

If power costs approach 'too cheap to meter', reverse-osmosis desalination may be by-passed due to the expensive membranes and bio-fouling...

Old-fashioned, low-pressure distillation plus heat-pump energy-recovery (to minimise thermal pollution may be the way to go...

Um, this work could be related to the recent discovery that if you zap alumin(i)um hard enough, the inner electron structure briefly mimics silicon, so material becomes transparent to far-UV... http://www.physorg.com/news167925273.html Big zap. Very, very briefly. Far-UV. Mind you, the life-times se...

Um, can your coil tolerate temperatures ~120C ? Co-winding 316 stainless steel capilliary tubing as used for HPLC (High Pressure / High Performance Liquid Chromatography) analysis hook-ups might do the trick. They'll take daft pressure ~ 200 Bar barely beyond finger-tight. Complex s/steel Ts & feed-...
