The use of batteries for vehicles and agricultural machinery promises to revolutionize the cultivation industry by lowering costs and improving production. From large tractors to small harvesting machines, all vehicles will be completely transformed by electric. On the other hand, current agriculture is under pressure: on the one hand the need to produce more food to avoid the food crisis.

In nanomachine towards the future

It's not the first and it won't be the last. Scientists from the University of Groningen (Holland) and the Empa research center (Switzerland) have created a nanometric transport system equipped with four motor units (translation: a “namomachine”). It's electric, four nanometers long and every half turn of the wheels has to fill up... It works thanks to a scanning tunneling microscope positioned above it, which transmits a tiny electric charge that causes reversible structural changes in the wheels (translation: … Read more
