Linear Laboratories operates (if you take their video at near face value) out of a barn in Texas and partners with Abtery in Sweden.   The partnership is significant, since Abtery is working on a Swedish regional airliner Elise (“Elektrisk Lufttransport i Sverige” or Electric Aviation in Sweden). The project is funded by the Swedish innovation agency Vinnova. And has multiple partners including Chalmers University.  Their goal is to apply the HET (Hunstable Electric Turbine) technology developed by Linear to real-world uses. Swedish Partners Anders Forslund, researcher at Chalmers in Gothenburg, Sweden, leads the development project Elise.  “We started a little later than they did in other countries but now we’re up and running probably faster than they do. Intensive research is ongoing …

Two Different Carbon Batteries

With lithium-ion batteries seeming to have topped out in their capabilities, battery researchers are looking at new ways of storing energy.  Zap&Go in England and Graphenano in Spain are exploiting a more common element  to good effect, crafting carbon batteries that charge quickly and last thousands of charge-discharge cycles.  Both attack their goals in very different ways. Zap&Go Carbon-ion Battery According to Microbattery.com, the Oxford-based organization Zap&Go has created and delivered a carbon-particle battery consolidating the superfast charging capacities of a supercapacitor to gain rapid charging and long cycle life.  Unfortunately, as far as electric vehicles go, it’s not quite ready for prime time.  The good news is that it’s on a well-structured timeline that will bring it to the vehicular world …
