Do you REALLY think that they're ignoring this, It's an excellent conspiracy theory that you have there, Jim. The record shows that US car makers ignored seat belts, pollution controls, air bags, crash zones, anti-lock brakes, and many other such innovations until they were either legislated screaming and kicking into it or were losing massive market share to offshore car makers who did innovate. Based on this track record, yes, one can easily imagine they may be ignoring it publicly. Mike --- Blue Wave/DOS v2.30 * Origin: Juxtaposition BBS.

On 10-17-97 Kyle Hearn wrote to all... KH>... if there is any way to solar power a first floor apt KH> with a western exposure or if it would be worth it at all KH> for the time being. Probly not. 70% of solar power being the hours just before and after solar noon... you'd loose at least half. As to a remote homestead... A new manufacturing method for the solar panels is in production. Look for prices to continue to fall significantly over time. I would not buy panels until at the last minute unless you see the economy becoming unstable, and wish to be set up before a crash. Earth bermed house on a SSE facing slope with diciduous trees; shade in the summer, sun in winter, no AC needed. Full sun in the 3-4 hours before and after solar noon; earlier or later in the day, the lower angle has too much atmosphere for much over 10% of rated panel power, even if on a tracker. Convert a chest type small freezer to a fridge- dick around on the thermocouple if you havta. 4X8 foot of solar will run it. I have run a peltier on 12v @ 5-6 amps, water cooled it with a line from my spring, and got frost on the 5"x5" condensor. It would keep the milk cold in a large picknic cooler, that I had added more foam insulation around... 3-4 cu ft. Another 4X8 foot array to power the rest of the house, stereo, 9" 60 watt color tv/vcr, one of my 12 volt desktop computers, RV florescents (when the tiny tube burns out, you can rig up a large long lasting tube of the same wattage that works years) a few halogens [bright but power hungry] and normal car bulbs in the rest of the house- yard light, shop, bath, etc. I have used inverters to run infrequently used stuff, like a blender, cake mixer, vacuum, etc. I have also seen inverters *fry* Canon BJ printers. some stuff nowadays has PFC types of power supplies, and no telling how it will react to the jags in inverter output. IF you see "PFC" skip it. ___ * OFFLINE 1.58 * Pessimist= an optimist in recovery --- Maximus 3.01 * Origin: * After F/X * Rochester N.Y. 716-359-1662 (1:2613/415) --------------- FIDO MESSAGE AREA==> TOPIC: 272 HOME POWER Ref: EEP00010 Date: 10/19/97 From: JIM DUNMYER Time: 08:55am \/To: MIKE ROSS (Read 2 times) Subj: RE: ENGINE DESIGN >JD> Low fuel economy and low torque are >JD> the big problems.

Would you please, tell > me how you come about your low fuel economy conclusion so I can > reconcilliate it with what I learned from the above? My stock ol' VW Jetta will do nearly 600 miles 'per tankful'. That is a meaningless measure if I ever heard one; I'll bet that there's a number of semi-tractors with huge fuel tanks that can go '1000 miles per tankful'. You're probably too young to remember the fuel crunches of the '70's and early '80's, but let me relate an example. One auto manufacturer (either Buick or Olds as I recollect) put an extra-large tank in their car so they could brag about 'mileage between fillups'. The car got the typical kinda poor mileage of the time, certainly less than 20 MPG, but it would go a long way on a tankful. My comment about low fuel economy (as compared to piston engines) comes from observations about turbine engines. I've never seen one yet that claims to do better than a recip. Your much-vaunted turbine conversions of a particular airplane is a good example. Check the details and you'll almost certainly find that the fuel cost per mile is higher for the turbine than for the recip that it replaced. There are mitigating circumstances that make it feasable to do such a transplant; it's done to DC-3s, too, you know. But overall fuel economy isn't usually the main reason. Cost of the conversion to the 'much simpler, only 1 moving part' turbine vs. simply replacing the old recip engine with a new/rebuilt one isn't usually the reason, either. --- FLAME v1.1 * Origin: Telnet toltbbs.com or call 313-854-6001, Boardwatch #55 (1:234/2)
