i was wondering if youve ever heard of a steam turbine....now if someone has
a lathe and some rally nipghty tools , you sould make a small steam turbine
in less than a single square inch...i also think that as far as fusion goes ,
lets jst leave that to he scientists, we do all remember hiroshima and
nagasaki right?? no ? thats cuz they were BLOWN UP BY NUCLEAD FUSION!

just thoughts ,

But I don't know about quality, cause I haven't ordered anything from them. They have pager motors for 2.50, but they aren't the one's that solarbotics has, here are the specs: 1.5 Volts, 80 mA. Motor body is 0.28” dia. x 0.67” long. Shaft is 0.03” (1mm) dia. x 0.16” long. Only bad part I can see about Allelectronics is NO microcore chips:(

13212 9 Apr 2000 02:29:36 -0000 74HC14 for a microcore, or 74xxx240? beam@sgiblab.sgi.com "Chris" How many neurons can i get on on 74HC14,would it be easy to attach two together without too much drain on the votage, and how would I attach them???

Is the neuron architecture for a 74xxx240 the same as the 74HC14???

Thanks for your help!
I'm new to walkers can you tell?

can't be completely mirrored (some atoms won't be covered). but if you had
an orb mirrored on the inside then ran a laser through it the light would
bounce off every side it would create an interesting site. you would see
the light and every so often there would be holes in the mirror so it would
appear to be a lantern.
