Nanocars

nanocar
This smart-looking image is a model of what James M. Tour at Rice University (Texas) and his research team like to call a 'nanocar'. The clustered molecules can roll around on a glass slide at about nine nanomiles per hour, and its wheels actually turn. The nanocar is no more than 4 nanometers across, which is slightly wider than a strand of DNA. Nanovehicles like these are designed to study the materials and movements, to make it easier for researchers to build more sophisticated molecular machines. Eventually the researchers want to build tiny trucks that could carry atoms and molecules around in miniature factories.

So in the future, we could have tiny ambulances racing through our veins instead of antibiotics.

One of the minor details that need to be solved: At room temperature, strong electrical bonds hold the buckyball wheels tightly against the gold, but heating to about 200 degrees Celsius frees them to roll.

I suspect this nano-car is currently the most energy inefficient car in the world. Hope this improves in future prototypes.

Should men be able to give birth to children?


Joyce Nabuurs: To me this question seems to be a logical next step in the emancipation movement of the past century. More and more women entered the workspace, but the responsibility for pregnancy and childrearing remained female.
