Graphene stress produces gigantic pseudo-magnetic fields

Researchers have reported the creation of pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory – just by putting the right kind of strain onto a patch of graphene (a sheet made from a single layer of carbon atoms). The finding, reported in Science, adds to graphene’s growing list of […]

Wireless Power Transfer Revisited

In 1904, renowned electrical impresario Nikola Tesla proposed a method whereby electrical energy could be transmitted without wires by using high frequency alternating current potential differences between two plates. For some reason (possibly the inconvenience of having two enormous, highly charged slabs of metal on either side of a toaster to make it work) the […]
