Comments on "Inventor of first practical transistor dead at 91" - The Register
Those who Google one T. Henry Moray's work on macro-magnetic field electro-resonance devices ("free" 'leccy drawn from a circuit built on Earth made to resonate with the Cosmos-scale tho' semi-subtle "Vibrations of the Spheres" (sic), more/less, per what I do grasp third-hand of Tesla's "Radiant Energy" hypothesis) will sooner or later scope out patent drawings and maybe a photo or two related to yet another apparent (tho' early) solid-state junction-based switching device. (Offhand, I suspect germanium due to the apparently high frequency being apparently switched, resonated and thus exploited.)
Dr. (PhD) Moray's little breadbox was apparently fitted with a ground rod, an antenna, and a "Bump-um-up" start-switch. It seems to have had a way of powering banks of lamps, multiple high-wattage heaters and suchlike *resistive* loads for indefinite periods, with no inclination toward overload or excessive heating-up on its own part. By the extant photos and descriptions of the nature of the light produced at his live demos, though, it seems quite clear that the as-delivered electrical fluid's base freq was likely much higher than our modern 50- or 60-cycle grids tend to provide today. Franlky, the effect looks to myself just like something a Tesla coil would produce if it rang like a bell, only with more amps and less volts.
Fatter wire, fewer turns, tuned just so... "Tickled" just so, like a resonance kick-start or a rubber hammer on the bell's rim... Hmmm...
The switching device, as illustrated on the sites I visited (you go too; kindly do!) looked (to myself) like a somewhat crude and certainly sizeable (as well as arguably effective) germanium (I deduce; crystal-based, anyway) switching device encapsulated in a blown glass envelope, when I first started puzzling over it on a few "Radiant Energy" Web sites a few months back.
One expects that a decently similar power-capture device might be built from off-the-shelf bits these days, really. Germanium's 300mV forward junction-drop sure takes better to a gentle initial ticklin' than any 700mV silicon-junction device might ever, when the steady-state alternating input energy's mebbe a bit on the feeble side... Hm. Then there's power MOSFETs these days...? (Gee, I sure would like to build one of those workhorses - looks like it;s Worth Doing Right.)
And that is Item One. As for Item Two:
Ah, yes, things worth building. Let us now (at last!) have ourselves a decent triple-expansion, triple-compound, 120° radial-axis Serpollet-design-derived steam-driven expansion engine (with multifuel-capable monotube boiler) for immediate application to the post-petrol challenges of fuel-versatile, closed-cycle, non-toxic (yes) light steam vehicle propulsion purposes, shall we? It seems clear that we shall soon need such cost-effective drop-in conversion packages as these for soon-to-be-moribund explosion-driven vehix, I think...
Seal 'em semi-permanently inside a cut-down 55-gal oil drum or similar enclosure; bolt 'em flat to the rear floor of the ol' SUV like a phat steel pancake. Couple the package's crankshaft thru a right-angle box directly to the differential's universal joint.
Valve timing works thru a simple linkage mech, cable-controlled (If neither digital telemetry nor hydraulic control methods hold any appeal) through the side of the can... Steam enters (and spent vapor exits) the propulsion mechanism through headers in the sidewall, too.
Steam lines route under the floor, of course. Well-insulated, of course, from boiler to engine. The "exhaust" vapor is piped forward to the condenser, naturally. Feed-pump and auxiliary electrical generation from a wee secondary direct-drive double-acting chuffer or hi-tech turbine/gearbox, off to the side under the bonnet. (I like the chuffer, mese'f.)
Little else need change, really... Likely gentler accel off the line, is all. Maybe no more shriekin' jackrabbit tyre-burns left at the crossroads... But no terrible limit on the top speed either, given only proper design. (The "throttle" sets that variable in place; remember it's the variable valve timing that sets the road speed and direction in these pseudo-retro "light steam power" rigs.) No torque converter needed at all, either, US EPA opinions to the contrary notwithstanding, thankyouveddymuch.
The 1913 world land speed record, remember, was set by a steamer. A novel steam bicycle won the annual student/open cycle race at MIT one early year, too, though the builder/driver/winner of that coal-burning three-lap winner tragically died of a heart attack at or a little before reaching the finish line.)
Now consider the Shabbos benefits of a near-silent propane-fueled steam-driven radial-engine lawn mower. Especially when one is the goyische neighbor and Saturday is the *one* day off... That one-lung blappin' stinkin' gas-burner's never ever likely to be made really quiet enough; we all know that.
So the boiler belongs where the V-8 once throbbed. Burn anything from wood- or hemp-pellets thru sugarcane bagasse to peanut oil to cheap perfume if that's all you got. Use a Fresnel array and align that monotube's tracking accordingly, and off you go. (Just Boil It.) Methane and suchlike gaseous scavenge can work well too, with platinated refractory wool sandwiched-in 'tween pancake-wound monotube layers for combustion efficiency's sake.
The condenser goes where the radiator once was. Then the feed-water is pumped back to the boiler as mentioned. Good seals make for little loss and very favorable vehicle range indeed.
Yep, this one's core components are sure due for a wireframe animation treatment any day now. A little OpenGL graphics creativity oughta' do it. You'll know when she hits the post-conceptual stage; just look for a Very Fancy Steam Engine Screensaver. But please, me beloved droogies, don't hesitate to beat me to it - machine shop and all.
Um, the physics review is already long since done. Easier to re-generate it all these days than in most, I'll warrant. I won't mind a bit, let alone sue, should anyone well-positioned pull this one off themselves bigtime, really, and (only collateraly; nothing more though perhaps tragically unavoidable) help starve The Dark Dickster's slick-sick-'n'-sinister torture forces right back to the place from whence they emerged to plague us all, I think. Let them eat their own diesel, they love it so. (Hmph.) Oh well.
Keep on thinking free, me laddy-bucks! Take up lathes and milling-machines and boring mills and diamond-plating surface-finishing gear for PEACE, shall we just, already? I do think so, and I already drive a fine homegrown 24-volt electric PPEV every day, all over town. Haven't burnt but eight measly gallons of diesel and some three quarts of naptha (as BBQ charcoal lighter) in the year gone by, truth be known to all. (My money stays mine longer, that way.)
Uh-oh. There's that pesky Al-Quaida(Halley-burton)/Al-Quaida(Exxon) yee-haw jee-hahd petroslavery-enforcement blacksuit goon-skwad a-circlin' back 'round th' block in this remarkably monolithic moonlight; they musta' homed in on me broadband agin... Glad that dang Hummer of theirs's got a rotted muffler... (Crap tinpot import steel, like as not.) Gotta' log off an' split now; hit the tunnels an' change me hairstyle right PDQ again. Can't sleep now, clowns'll tase me...
Peace. I'm out.
