How many here agree that English is the language of the world? Just wondering ,I could be wrong. >> Goedendag, >> [quoted text clipped - 17 lines] > -- > Anon Goedendag (a Dutch word), I would have posted English/American sites if they existed. No doubt this German project will sparc some ideas outside of Germany and we'll see similar sites in the 'language of the world'. Those *&^%$# Germans are just to modest, they need a Dutchman to spread the word. Use http://babelfish.altavista.com for online translation (and a good laugh, automatic translation is far from perfect yet).

It may not be perfect (far from it, in fact) but it's more fun than some TV comedy shows:-) > Vriendelijke groeten (also Dutch), Ron van Sommeren > near Nijmegen, the Netherlands I was over in your neck of the woods last month Ron. It rained the whole time and I couldn't get out quickly enough, although I did try :-) 148mph along that road they've built in the north of Holland connected to two peninsulars going to Leeuwarden/Groningen. Water both sides, water coming down from above and only lightning to illuminate the way:-)  SignatureBeav VN 750 Zed 1000 OMF# 19 "Beav" wrote in > I was over in your neck of the woods last month Ron.

We are having lovely weather here in September, somebody up there must have switched August and September. > ... and I couldn't get out quickly enough, although I did try :-) 148mph Good thing the police did not see you, you would have had to hand over your car to them. Verrrrry stiff fines ... Vriendelijke groeten ;-) Ron near Nijmegen, the Netherlands 2007 E-fly-in, Aug.26. http://home.hetnet.nl/~ronvans/ | That would be interesting if it was in English. Try using http://www.google.com/language_tools or http://babelfish.altavista.com/ to do the conversion for you. They're not perfect, but it's often good enough. | How many here agree that English is the language of the world? English is perhaps the most commonly used language on Usenet, the Internet, and the WWW. If there is a `universal language' for these things, it would be English. However, English is *not* the language of the world, and it's incredibly arrogant for an English speaker to suggest that. And besides, even if you don't understand the language, you can always gawk at the pretty pictures! | Just wondering ,I could be wrong. I guess you could ... | >> Motor: 10mm outrunner kit from http://www.batt-mann.de | >> Fuel: iquid hydrogen (99,9%) in two plastic bottles at 10 bar pressure | > | > The fuel is cryogenic? Like -253 degrees centigrade? How does | > it stay cold? `10 bar pressure' suggests pressurized gas. Looks like a fuel cell too. Neat concept. | > Or is it just pressurised gas? SignatureDoug McLaren, dougmc@frenzied.us Donuts. Is there anything that they can't do? --Homer > That would be interesting if it was in English. It was pretty interesting in German too. How many here agree that > English is the language of the world? Engllish is an interntaional language, but it's not the language of the world. Just wondering ,I could be wrong. You could also try learning a 2nd or 3rd language yourself. It's not quite as easy as you seem to imagine. SignatureBeav VN 750 Zed 1000 OMF# 19 Goedendag ;-) It can fly for 6 minutes, it is said somewhere in the videos. At 1,1kg the fuel cell is pretty heavy, it can be made much lighter. Full scale developments: http://www.initiative-brennstoffzelle.de/de/ibz/live/nachrichten/detail/229.html By the way, the pictures are not mine, they were made by Paul-Henri Tirtiaux from Belgium. I could not make it, my back is giving me troubles (that's what you get when you're over 2 meters tall :( ), I could not drive the 450km. Next year ...

Ed Cregger Well, I think the thing is pretty damn good!! A lot of modellers have enough trouble with their 100 year old technology engines and 30+ year old technology radio gear. I think the guy deserves full congratulations and top marks for inventiveness, skill, knowledge and practical application! Very well done indeed!
