"Resulting replacement power... requirements for electric... is obtained"
http://www.grc.nasa.gov/WWW/RT/2004/...S-johnson.html
"Future advanced aircraft fueled by hydrogen are being developed to use electric drive systems instead of gas turbine engines for propulsion. Current conventional electric motor power densities cannot match those of today’s gas turbine aircraft engines. However, if significant technological advances could be made in high-power-density motor development, the benefits of an electric propulsion system, such as the reduction of harmful emissions, could be realized." --- Mark |

Sailing comes to mind -- it's like flying but the airfoils are more adjustable and mostly vertical. |

Sailing comes to mind -- it's like flying but the airfoils are more adjustable and *mostly vertical. No, I'm flying Cessna's with a CFI friend on board. I don't have access to an LSA right now, which is just as well, because I plan on buying an LSA and it would be prudent to have a CSI that's proficient in that make/model train me. AFA alternative enjoyment to electric recreation, been doing it for years. My 14' boat has a large solar panel from West Marine, (which is unnecessary as it turned out) that charges the deep cycle battery which energizes my powerful electric motor/prop manufactured by Minkota. Pushes white water off the bow, and it's never gone dead. Ran it continuously for 4 hours before. So quiet and pleasant. The fish follow me around and I hear everything. Good for sneakin' up on stuff too! My interest for discussing electric airplanes here is to share the latest developments in this field, because that is really what people want, whether they realize it or not. The military and NASA sure know it. Flight schools want it. Really who wouldn't? So smooth, quiet, clean, simple, and efficient. I'd buy a sailboat ( I used to sail ) but I like to keep my toys locked up on my own property. This is possible but it'd require adding a 4th building to my place and that's just too much indulgence. --- Mark --- Mark |

Maybe it would be prudent for you to get seat time in an LSA before you shoot off your mouth like you are some kind of ****ing expert? Maybe that's just me, wanting to be all accurate and non-fukknutzoiod. -- A fireside chat not with Ari! http://tr.im/holj Motto: Live To Spooge It! |
