Todd Sayers: Why non-dilutive funding is revolutionizing B.C.’s cleantech sector

"...The diversity of these recipients is remarkable. Takachar, for instance, is making biomass-based chemicals and biofuels economically feasible by prototyping a small-scale, portable biomass conversion unit on tractors and pick-up trucks to process raw biomass on-site in remote communities. Invinity is accelerating the adoption of renewable energy by delivering vanadium flow battery storage for electrical grids worldwide, while HTEC is building hydrogen fueling stations that can withstand extreme weather conditions..."

Wafer-thin supercapacitor stays strong when bent out of shape

"...Scientists have developed a new type of supercapacitor with the kind of flexibility and durability needed to feature in footwear and clothing, along with other devices making up the Internet of Things. The advance stems from a novel manufacturing method that produces a wafer-thin energy storage device that can be bent and stretched out of shape, all the while maintaining its impressive performance. Supercapacitors have some unique abilities when it comes to energy storage..."

Capacitor-packin' BCool digital thermometer has no need for a battery

"...Although digital body-temperature thermometers may be easier to read than their analog counterparts, there's always the chance that their battery will go flat between uses. That's where the BCool thermometer comes in, as you just give it a few shakes to power it up. Manufactured by Baracoda Daily Healthtech, the BCool features an integrated supercapacitor instead of a battery..."

Bike-mounted Air device monitors air quality along cyclists' routes

"...Users can also set the Air to work as stationary sensor at their home or workplace, when their bike isn't in motion. However it's being used, it will alert its user to changes in local air quality via an LED that changes colors accordingly. Power is not provided by a battery, but instead by a supercapacitor..."

Plants with electronic roots act as energy storage devices

"...An interesting new research project out of Sweden's Linköping University has demonstrated how plant roots can be used as energy storage devices. The scientists see the process, which requires the plants to be watered with a special solution to make their roots electrically conductive, as as proof-of-concept for a root-based supercapacitor, as well as for biohybrid systems that meld biological processes with electronic functionality. Carried out at the university's Laboratory of Organic Electronics, the breakthrough builds on previous research led by Dr Eleni Stavrinidou's Electronic Plants Group..."

Lithium-carbon battery lets electric mopeds recharge in 90 seconds

"...According to analysis carried out on a simulated fast food service with a 25-km (15-mile) radius, using a conventional 500-Wh battery would require electric mopeds to pull over mid-shift and spend 30 minutes recharging. For the sake of comparison, the team says its novel battery pack could recharge these vehicles in 90 seconds thanks to its ultra-fast charging rate. In addition, the team's lithium-carbon battery uses no rare-earth metals and is entirely recyclable, and is also claimed not to be susceptible to thermal runaway events that can cause batteries to overheat and be destroyed..."

Accordion-inspired supercapacitor blends flexibility and high capacity

"...Flexible electronics could open up some interesting possibilities in bendy displays, wearable devices or solar energy, but developing flexible energy storage devices to power them is another challenge entirely. Scientists in China have demonstrated a creative solution to this problem, designing a novel supercapacitor that maintains high capacity when stretched and twisted thanks to accordion-style wrinkles. While today's lithium batteries have a high energy density and can therefore store energy for long periods of time, they have a low power density, meaning they can only deliver small trickles of power and take a long time to charge up..."

Dust-sized supercapacitor packs the same voltage as a AAA battery

"...By combining miniaturized electronics with some origami-inspired fabrication, scientists in Germany have developed what they say is the smallest microsupercapacitor in existence. Smaller than a speck of a dust but with a similar voltage to a AAA battery, the groundbreaking energy storage device is not only safe for use in the human body, but actually makes use of key ingredients in the blood to supercharge its performance. The scientists behind the new device were working within the realm of nano-supercapacitors (nBSC), which are conventional capacitors but scaled down to the sub-millimeter scale..."
