Scientists have created a rechargeable battery using the lignin from pulp and paper mills

Scientists have discovered that lignin, a plentiful byproduct of the pulp and paper industry, can be used to store an electrical charge. They've used the material to create a prototype lignin-based rechargeable battery, and suggest that it could one day be used as a less expensive, safer alternative to the precious metals currently utilized in battery cathodes.  Read More

When you want to isolate communications between two devices or locations, a fiber optic link is one of the best ways to go. Under some circumstances, however, you might also want to isolate the transmission of power – in situations where traditional copper wire might prove unsafe or impractical, for instance. That’s why researchers at Sandia National Laboratories are developing a power-over-fiber (PoF) communications cable. It carries not only data, but also optical power.  Read More

Pavegen tiles harvest kinetic energy from pedestrian traffic

Can you imagine the power of 50,000 steps a day? Well, Laurence Kembell-Cook, the director of Pavegen Systems imagined it and created Pavegen tiles - a low carbon solution that aims to bring kinetic energy harvesting to the streets. Not surprisingly, the tile is receiving a great deal of attention as a solution for power-hungry cities with a lot of walking traffic.  Read More

The amusement park features over 40 rides and attractions (image from Wunderland Kalkar)

The Wunderland Kalkar amusement park in Germany has been converted from a disused nuclear power station, following the government's decision to abandon all nuclear energy plants. The site was sold in 1991 to a Dutch investor who, leaving the reactor building in place, created Wunderland Kalkar. The proportions of the park are enormous, positioned on over 55 hectares (80 football fields) and features over 40 amusement attractions.  Read More
