NiceHash, a Slovenian-based marketplace for mining digital currencies, says its payment system has been hacked and the contents of its Bitcoin account stolen. According to its Facebook page, every week NiceHash paid out millions of dollars in Bitcoin weekly, meaning the loss could be significant, especially since Bitcoin has had a precipitous rise in value. Uncertain is whether NiceHash users’ accounts have also been hacked. In light of the unknowns, NiceHash has closed down operations for 24 hours. Meanwhile, Bitcoin enthusiasm continues to rise, as illustrated by a 40 percent jump in price yesterday. Continue reading Despite Hacks, Cryptocurrency Mania Drives Up Bitcoin Value

Energous and Witricity have developed new ways to charge smartphones, tablets and other small devices without needing wires to plug them into an outlet. Energous’ WattUp technology allows users to recharge phones in special cases or receivers that can pick up signals from a transmitter that is plugged in more than 10 feet away. Toyota and TDK are already planning to utilize Witricity’s wireless charging technology in upcoming hybrid and electric cars, and car batteries.

Scientists and engineers are working towards making wireless power possible by harvesting and transforming existing energy from the world around us. Models they have looked at include nanoscale pillars that turn waste heat into electricity and a spongey smartphone case that generates electricity from sitting on a vibrating surface. One source of energy is thermoelectricity, which works by creating electricity from the current created by electrons moving from hot to cold, an approach that may be ideal for humans.

A materials research team at Vanderbilt University has designed a new supercapacitor that is made of silicon and has the potential to power many types of devices, from solar cells to mobile devices. The supercapacitor may be made from excess silicon and can provide significant savings in manufacturing costs. The technology cannot store energy the same as lithium-ion batteries, but supercapacitors have promise in consumer devices.
