One-Molecule Nanocar Takes a Test Drive
MrSeb writes "Just a couple of months after nanoengineers at Tufts University developed an 18-atom single-molecule electric motor, researchers from the University of Twente in the Netherlands have gone one better: They've made a car using just a single molecule. To create the vehicle, Tibor Kudernac and colleagues crafted a molecule with a long body and four 'paddle' (wheel) features attached at each corner. The molecule was created with a bottom-up process, where each part of the molecule is gently slotted together. By applying tiny amounts of electricity with a scanning tunneling microscope (STM) to the finished vehicle, the wheels are forced to make a quarter turn. The wheels naturally take another quarter turn to restore equilibrium — and then the STM starts the process all over again. The end result is very slow forward movement — six nanometers per 10 electric pulses."
Not at all. Have you seen the parking fees in town lately? This product serves a real need. Now you can drive to work on a molecule, and keep it in your pocket during work hours. Moreover, it's eco-friendly. I'm told molecules run on electricity.
Where do you store the millions of STMs that you need to run them?
In the millions of molecular trunks, of course.
Someone will always want a bigger molecule. The longer, the better. Huge chains of atoms that demand more and more electric.
Why can't people be happy with what they've got?!?
