3D water sensors
One of the great problems worldwide is the scarcity of water, added to pollution. 3D sensor technology provides the ability to regularly monitor and measure pollution in water on a large scale.
The current innovation is that these 3D sensors created by a group of researchers from Columbia University, allow to control water on a small scale in an economical and efficient way.
The sensors collect data on pH, temperature, chlorine levels and can detect pathogens and other pollutants. These measurements are sent wirelessly to a central system.
Even with the possibility of a sensor failure, the others will continue to work as part of a cluster system, which means that they can be deployed through a water network and a distribution system.
Recovering ancient strains
Climate Change has increased the need for new agricultural practices in the production of grapes, since the wine industry is being affected by Global Warming because the increase in temperatures is killing some strains, which are not capable of adapting to new ecosystems.
Bodega Torres, located an hour from Barcelona, is determined to reverse this problem, so it has dedicated itself to investigating the potential of reviving regional varieties of wine grapes, which are capable of growing, in hotter and drier climates. .
These strains were mixed with other stronger and more resistant to certain diseases years ago and the original was lost. Now, in collaboration with the National Institute of Agricultural Research of France, these ancient varieties trying to recover in greenhouses.
Some of these varieties have the ability to ripen just before winter and thus can retain high levels of water. Paradoxically, the future of the wine industry could be in the past.
Clean and environmentally friendly supercapacitors for transport and energy efficient applications
Supercapacitors have a charge storage capacity 1,000 times greater than that of capacitors. An initiative of the European Union has presented the new generation of environmentally friendly, cost-effective and high performance ultracapacitors.
Capacitors, essential components of electrical circuit boards for years, now have a capacitance thousands of times greater than their original design thanks to technological advances. By expanding their charging capacity, supercapacitors or ultracapacitors are powerful enough to store energy in hybrid and electric vehicles or in technologies based on intermittent renewable energy sources.
The ENERGY CAPS (Development of a sustainable and safe hybrid supercapacitor with high specific energy and maintained high specific power and cyclability) project, funded by the European Union, aimed to address some of the current challenges associated with hybrid supercapacitors.
From bracelet to battery
We have bracelets that can measure steps, calories burned, and even track routes; Apparently the next step is to wear bracelets, which collect energy from movements to power the batteries of various devices, such as a smartphone or a pacemaker.
Researchers from Chongqing University of Technology and the Sichuan Chinese Academy of Engineering Physics have designed a bracelet, which can collect biochemical energy from wrist movements, to convert it into electricity.
The bracelet uses electromagnetic induction, through the use of conductive copper coils, which are placed inside the bracelet. Inside it, the magnets rotate around the bracelet in response to wrist movements and as they pass through the coils, they create an average power of more than 1 milli watt.
