Current-limiting Superconductors

Current-limiting Superconductors Current-limiting components based on the latest generation of superconductor materials are proving tough enough for deployment in power plants to protect equipment, says The superconducting material is composed of yttrium, barium, copper, and oxygen (YBCO) — and you can see a batch being cooked up here. For current limiters, the YBCO is grown just 1 micrometer thick on stainless steel strips only millimeters wide. Below -183 C (90 K), the component acts as a superconductor, but if the current spikes above the design value, then the superconductivity collapses and the remaining high-resistance steel strip limits the current. After the event, the device cools down and regains its normal function.

Big Steel Goes from Power Parasite to Producer

Big Steel Goes from Power Parasite to Producer The world steel industry consumes a significant portion of energy generation. Now, engineers have found a way to harvest the hydrogen- and carbon-rich exhaust gases (which are actually low quality) from the process — then compress, clean, and mix them to fuel a gas turbine generator. Power Magazine points out that reduction of greenhouse gases is another benefit.

Smart Circuits Help Utilities Solve Problems

Smart Circuits Help Utilities Solve Problems A Pacific Northwest utility is using the enhanced data acquisition capabilities of "smart circuits" to optimize its distribution management system for quicker response times, according to Transmission & Distribution World. In the event of changing loads or a fault, intelligent end devices supply the information required by operators to identify repair or rerouting needs.

Touchscreen Data Recorder

Touchscreen Data Recorder Sensors and instrumented systems are of little use if the data is not indicated and recorded. This touchscreen-based data acquisition and display device can economically accept and display up to 300 inputs, and explains that an FDA-compliant security option makes the unit especially applicable to biotech and food industries.

Chirpy Insect Inspires Airflow Sensor

Chirpy Insect Inspires Airflow Sensor Cricket abdomen hairs used by the chirpy insects to sense approaching enemies are the unlikely inspiration for a synthetic airflow and vibration sensor. For the manufactured version, researchers have developed a way to apply an alternating voltage that adjusts the springiness of the "hair", and tunes it for a tenfold increase in sensitivity at a given frequency.

Printing the Way to Solar Efficiency

Printing the Way to Solar Efficiency For the solar industry to commercially match conventional power generation, PV panel manufacturers must reduce product costs so that the electricity produced costs no more than one dollar per watt. While one route is to improve mass production efficiencies using current technologies, ElectroIQ explains that another method is to upgrade technology such as through the use of non-contact nanoparticle printing.
