New method for converting solar energy into electrical power using photo-bioelectrochemical cells

One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle — sometimes doubling in volume, and then shrinking back. This can lead to repeated shedding and reformation of its “skin” layer that consumes lithium irreversibly, degrading the battery’s performance over time. Now researchers have found a novel way around that problem: creating an electrode made of nanoparticles with a solid shell, and a “yolk” inside that can change size again and again without affecting the shell.
The production of energy from natural gas without generating carbon dioxide emissions could fast become a reality, thanks to a novel technology. Researchers have been researching an innovative technique to extract hydrogen from methane in a clean and efficient way. After two years of intensive experiments the proof-of-principle has now been provided. With the experimental reactor running reliably and continuously, the future potential of this technology has become apparent.
Researchers are looking beyond the usual suspects in the search for microbes that can efficiently break down inedible plant matter for conversion to biofuels. A new comparative study finds the natural abilities of unconventional bacteria could help boost the efficiency of cellulosic biofuel production.
Ontario’s Independent Electricity System Operator released its annual “Electricity Data” report on Tuesday, and it breaks down the supply mix in 2015, 2014 and 2013. On the surface there hasn’t been a big shift over the past three years. We see that nuclear and hydro output has been fairly consistent. Natural gas generation was up slightly in 2015 compared to 2014, but was still lower than 2013 levels. Coal has been completely phased out, but at only 2 per cent of the mix in 2013 it wasn’t a dramatic change. Wind as a share of the electricity mix has doubled to 6 per cent since 2013. Electricity from biofuels more than doubled, but still represents less than 1 per cent of the mix. Then there’s solar. Looking at 2013 data, you might be confused …
