Here's a skateboard that doesn't need a hill (or a push-off from your foot)
for propulsion. James Howland and his project buddies, Pat Rimel and Nate
Davis, created a motorized mountainboard as a project for their mechanical
engineering class at Colorado
The gadget has a handheld speed control, and the team was able to get the board
up to speed of 13 miles per hour. The speed decreases while traveling up hills
but still has enough torque to conquer hills with ease. The mountainboard also
has buzzer on the nose that acts as a horn.
A new federally sponsored manufacturing innovation center to strengthen US manufacturing abilities in fiber-reinforced composites has formed, bringing together materials suppliers, OEMs, university R&D labs, and national labs.
