How high can you fly?
I think the 'electric' powered aircraft is little more than a toy. See http://www.youtube.com/watch?v=fWoLsJz8J5U |

How high can you fly? 95,000ft? This will soon be a real consideration. I don't have the figures available at the moment, but I can tell you what to look for and what to do. Find the Vs for a C152. Find the Mmo, likely about M.75. Your max altitude is where the true Vs == Mmo. * * * * * * * * * * * * *-ash * * * * * * * * * * * * *Elect Cthulhu! * * * * * * * * * * * * *Vote the greater evil. Thank you so much! Can't wait to run the numbers. Had this been a contest, you just walked off with a new trophy. --- Mark |

This video does. http://www.youtube.com/watch?v=t2IrN...eature=related Cruises...90% efficient, 10% heat. Max. Climb...80% efficient, 20% heat. Heat is not a factor. Replacing the internal combustion engine which yielded...85% noise and heat, 15% efficiency. Flys 1 1/2 Hours. And it's beautiful. Where do we send the check?? --- Mark |

While I think Mark is starry eyed (at best,) Heh. prognosticate (prg-nst-kt) tr.v. prognosticated, prognosticating, prognosticates 1. To predict according to present indications or signs; foretell. See Synonyms at predict. 2. To foreshadow; portend you are technically mistaken in the above assertion because in fact electric airplanes (actually solar- electric airplanes) hold some world records: That's not technically. That's actually. When the solar-electric "Helios" reached 96,863 ft in 2001 it set the altitude record for highest altitude flown by non-rocket powered aircraft.. So electric (specifically solar-electric) is indeed superior for certain applications. I estimated 95,000ft. Just not general aviation. Just not general aviation today. In 2055, you take off burning fossil fuel, "you go jail". --- Mark |

AIRPLANE: engine-driven flying vehicle: a vehicle with wings and a jet engine or propellers that is heavier than air and is able to fly [ Late 19th century. French aéroplane aéro- ( Greek aēr "air") + - plane ] Any of various winged vehicles capable of flight, generally heavier than air and driven by jet engines or propellers. air·plane (er′plān′) noun a fixed-wing aircraft, heavier than air, that is kept aloft by the aerodynamic forces of air as it is driven forward by a screw propeller or by other means, as jet propulsion --- Mark |

There may be some niche applications, like unmanned surveillance, where they might be useful but they are terribly fragile. And a range of 90 minutes.... That's barely enough to start a crosscountry. If you want a fun machine that goes places cheaply The Bantam B22 Microlight has a 4 hour range at 60+ knots. |
