The 75 MPH Bicycle That's Powered by a Jet Engine [Zoom]
http://technorati.com/posts/NBMPEEukX%2BFGiVkxhFAj7r%2BYWjEmOFqedKUdUAW9s%2BE%3D
Robert Maddox is a builder and seller of real pulse jet engines with powers
up to 1000 pounds... and if that's not a cool enough hobby, he's also bolted
one to a bicycle. The 50-ish pounds of thrust developed by the engine could
push the bike up to 75 MPH, which would be a real bone-shaker of a ride. And
a deafening one too: the pulse jet engine makes a frightening racket, and
its humming sound earned the 2nd World War cruise-missile V1s which used
similar engines the nicknames buzzbomb and doodlebug. You can hear and see
the results of this DIY craziness in the video.
..........................................
During WW-2 a kid in my 3000 population home town bought two of the little
"buzzbomb" engines designed to be built into model airplanes and fastened
them to his bike. Getting up enough bike speed to start the engines was the
big problem but once started, they would wake up every dog in town and you
could hear them running a mile away. He said he had to turn off the fuel
supply to stop because the old fashioned "coaster brake" on his bike
wouldn't do it with the engines running.

First thing I thought when I saw that video.....extra fuel line and a spark
plug, ta da, afterburner! :-)
Probably just as good I don't have kids, eh?

There are a lot of these vids on youtube. Many use Garret turbos. This
would make a great science project provided there is plenty of adult
supervision...more like collaboration. That's a lot more exciting than the
hot wire anemometer I made in 7th grade. Hmm..oldest is in third
grade...few
more years.
