Electric skateboards are certainly building up some momentum as a form of urban transport, and they seem to just keep getting lighter and lighter. Florida-based start-up Marbel is the latest to set its wheels in motion, this week launching a crowdfunding campaign for what it claims to be the world’s lightest electric vehicle – the 9.9 lb (4.5 kg) Marbel.
Last week, the story broke of an extremely hopeful “Ryden dual carbon battery” developed by Power Japan Plus (PJP), and responses have ranged from optimistic, to pessimistic reminders that unfulfilled battery “breakthroughs” have been touted before. If you’re just hearing of this prototype chemistry now being proof tested by an undisclosed “famous” go-cart race team and with results expected in
Segway made a name for itself with self-balancing, two-wheeled scooters that could quickly get pedestrians around town with a minimal footprint. Despite the hype leading up its launch, it did not, as it turned out, “change the way we think of cities”. It did, however, change the way we think of mall cops – but the Segway’s success in the
Consolidated Edison is one of the distribution utilities that will be acutely affected if New York’s Reforming the Energy Vision, or REV, proposal becomes a reality in the coming years. The utility is not necessarily fighting the changes happening at the grid edge. It already has a “utility of the future” group, explained Andrew Reid, a senior engineer at Consolidated
Elon Musk has probably been given a lot of advice during his time at Tesla–some good, and some bad. Bond manager Jeffrey Gundlach is the latest to offer his own take on the business to Musk though–and it isn’t what you might be expecting. According to Bloomberg, Gundlach has suggested the Tesla Motors [NSDQ:TSLA] CEO get out of the car-making
Researchers at the University of California, Riverside have developed a novel nanometer scale ruthenium oxide anchored nanocarbon graphene foam architecture that improves the performance of supercapacitors, a development that could mean faster acceleration in electric vehicles and longer battery life in portable electronics. The researchers found that supercapacitors, an energy storage device like batteries and fuel cells, based on transition
Interference-free charging is a major prerequisite for the economically efficient use of electric vehicles. After about 120,000 km driven electrically, the RheinMobil project has proved that a combination of quick and conventional charging is ideal for the battery performance: The controlled mix ensures a high utilization rate of the vehicles and protects the battery. RheinMobil is a joint project of
Researchers around the world have been working to harness the unusual properties of graphene, a two-dimensional sheet of carbon atoms. But graphene lacks one important characteristic that would make it even more useful: a property called a bandgap, which is essential for making devices such as computer chips and solar cells. Now, researchers at Massachusetts Institute of Technology (MIT) and
Toshiba Electronics Europe (TEE) has expanded its family of high-efficiency and compact super junction MOSFETs with devices offering voltage ratings to 650V. The new 650V MOSFETs are suited for applications that may have to operate in environments with fluctuating mains supplies or very low temperatures. Extended voltage capability also supports improved design flexibility by increasing safe operating margins. Toshiba’s latest 650V
At PCIM Europe, LEM S.A. announced the addition of three new HO series of high performance current transducers which extend nominal current measurement up to 250A and offer a range of mounting options. The recent launch of the first devices in the HO series enabled a breakthrough in the trade-off between performance, cost, size and mounting versatility. These three new
