Glucose to Power Pacemakers

Researchers at the Technological Institute of Energy, Valencia, Spain, are working to create a bio-battery that uses blood glucose to produce energy. Such a battery, they say, would cut down on the number of surgical interventions a pacemaker user must undergo.

Public Lighting System Runs on Solar and Wind Energy

A researcher at the Barcelona College of Industrial Engineering, in collaboration with the company Eolgreen, has developed the first autonomous industrialized public lighting system that works with solar and wind energy. This system, developed after four years of research, is designed for inter-urban roads, motorways, urban parks, and other public areas. It is unique in the world, and reduces the cost by 20% compared with conventional public lighting systems. The prototype is 10 meters high and is fitted with a solar panel, a wind turbine, and a battery. The turbine runs at a speed of 10 to 200 rpm and has a maximum output of 400 watts. Work is being done on a second prototype generator that runs at a lower speed (10 to 60 rpm) and has a lower output (100 W). An electronic control system manages the flow of energy among the solar panel, the wind turbine, the battery, and the light. Source:

Glass as Electrode Makes Batteries More Efficient

Today’s batteries provide a reliable power supply for our smartphones, electric cars and laptops, but are unable to keep up with the growing demands placed on them. Researchers have discovered a material that may have the potential to double battery capacity: vanadate-borate glass. The glass is being used as a cathode material, which is made of vanadium oxide (V2O5) and lithium-borate (LiBO2) precursors, and was coated with reduced graphite oxide (RGO) to enhance the electrode properties of the material. The vanadate-borate glass powder was used for battery cathodes, which were placed in prototypes for coin cell batteries to undergo numerous charge/discharge cycles. In tests, the glass electrodes demonstrated a vast improvement in these batteries’ capacity and energy density. Source:

Going Off-Road With Hard-Carbon Lithium-Ion Battery Technology

EnerDel’s second-generation Mobile Hybrid Power System (MHPS) was delivered in May to the U.S. Army Corps of Engineers’ Research and Development Center in Champaign, IL. It offers a reduction in diesel fuel consumption of up to 70% “in most use cases as demonstrated by the military.” The MHPS-80, as delivered to USACE-ERDC, features an onboard 15-kW charging generator, an 80-kW·h lithium-ion battery system, power inverter, and dc input for wind and solar energy.

Aircraft with Hybrid Engine Can Recharge in Flight

Researchers from the University of Cambridge, in association with Boeing, have successfully tested the first aircraft to be powered by a parallel hybrid-electric propulsion system, where an electric motor and gas engine work together to drive the propeller. The demonstrator aircraft uses up to 30% less fuel than a comparable plane with a gas-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.
