Want to scavenge the gentlest of Wind Energy? This tiny device can do

Who could imagine to be able to scavenge wind energy from the breeze as gentle as the one created by a brisk walk? A ‘tiny wind turbine’ designed by researchers in China can do so, contrary to the fact that wind available on land is not strong enough to drive commercial wind turbine blades. The method is low-cost and effective way of collecting gentle breeze as a micro-energy source.

Technically, the device is not a turbine. It is a nanogenerator composed of two plastic strips in a tube that clap together when there is airflow. Based on the phenomenon called triboelectric effect, the two plastics become electrically charged after separated from contact, and is akin to rubbing a balloon to the hair. However, the electric charge generated by the two plastics is seized and stored, rather than making the hair stand up like that of Einstein.

“The mechanism allows to collect all the breeze in everyday life,” says a senior associate behind the design. For trial, the nanogenerator placed on a person’s arm and airflow in the swinging arm enough to generate power.

With wide Scope for Improvement, pilot shows efficacy of mechanism

For experimentation purpose, a breeze as light as 1.6 m/s enough to provide energy the triboelectric nanogenerator created by the team. Meanwhile, the nanogenerator performs best when wind velocity is in the range 4 to 8 m/s – a speed that enables the two plastic strip to clap in sync. In addition, the device comprises a high wind-to-energy conversion efficiency of 3.23%, which is higher than previously reported values of wind energy harnessing. Currently, the device can power up to 100 LED temperature sensors and lights.

Machine Health Monitoring Market Players Find Sizeable Growth Opportunities in Oil and Gas Industry

Sturdy growth of oil and gas industry across the world is estimated to stimulate marvelous demand opportunities for vendors working in the global machine health monitoring market. Machine health monitoring systems are gaining popularity across diverse end-use industries owing to their ability to efficiently track the overall health and performance of machines. In this process of machine health monitoring, the vibration, current, temperature, and RPM are recorded and compared against set thresholds. This helps in finding out any signs of degradation of machines.

Regular Sports and Entertainment Events Attracting Growth

Sports and massive entertainment live events act as prominent growth generators for the stadium lighting market. LED stadium lighting is mostly preferred for event purposes nowadays due to its property of withstanding different weather conditions. Therefore, manufacturers in the stadium lighting market are concentrating more on developing sturdy and durable LED stadium lightings.

COVID-19 Impact on Stadium Lighting Market

The novel coronavirus outbreak has recorded immense loss across almost all sectors and businesses around the world. The stadium lighting market also bore the brunt of the deadly virus outbreak. Due to strict lockdown implementations, all the production facilities and manufacturing units were shut. Disruptions in production and supply chain mechanisms resulted in tremendous losses for the stadium lighting market.

The lockdown restrictions have also paused sport and entertainment events worldwide, thus leading to a decrease in the demand for stadium lighting. However, the restrictions are being relaxed by the governments of various countries in an effort to bring the declining economy back on track. This aspect may serve as an opportunity for the stadium lighting market to revive its growth.

Some sporting and entertainment events are also being resumed with limited seating capacities. This factor provides a ray of hope to increase the growth rate of the stadium lighting market.  Some well-entrenched players in the stadium lighting market are Zumtobel Group, Philips Lighting, General Electric, Eaton Corporation, Panasonic, LG Electronics, and Cree.

Sodium-ion batteries viable alternative to Lithium-ion batteries, says research

Whilst for energy needs of a wide range of applications, lithium-ion batteries are the choice of electrochemical energy storage systems, currently, other types of emerging battery technologies are on the path to become equally dominant.

Among them, sodium-ion batteries display massive potential to represent next-gen low cost and eco-friendly energy storage solution. The different applications require diverse key performance indicators and the market diversification is mainly pushing the sodium-ion technology closer to the market.

To assess the current status of sodium-ion technology from materials to cell development, a team of scientists combined their knowledge and expertise, and offered a realistic comparison of key performance indicators for lithium-ion batteries and sodium-ion batteries.

Large-scale Production of LIBs has Environmental, social Implications

Lithium-ion batteries play a key role for transition to a low carbon economy. However, as the demand for lithium-ion batteries expands, the mass production of lithium-ion batteries is associated with environmental and social challenges. This is triggering large attention to find alternative energy storage solutions based on materials that can be obtained in a responsible and sustainable manner. In this scenario, sodium-ion batteries represent a low cost alternative that is sustainable and is a more eco-friendly energy storage technology.

Meanwhile, sodium-based batteries offer a number of attractive properties. Sodium-ion batteries are low cost, have a secure supply of raw materials, and use sustainable precursors. Besides this, sodium-ion batteries are considered a drop-in technology which could benefit from the manufacturing already existing for lithium-ion batteries.

The paper on the study published in the Journal of Power Sources, the team of scientists analyze the probability of sodium-ion batteries taking a lead spot in the energy storage market. Led by researchers at the University of Warwick, the paper includes researchers from Humboldt University and College de France among others.
