Now the use of chemical fuels for power generation methods inevitably generates heat waste. If scientists can use the low-grade heat generated in these power generation processes to recycle the waste heat contained in them, it can further increase energy conversion efficiency and reduce waste. A team of engineers at Penn State University developed a "Thermally Regenerative Ammonia Battery (TRAB)" that can recover low-grade thermal energy and generate electricity.
Low-grade thermal energy refers to thermal energy that is difficult to use, such as thermal energy of seawater, thermal energy of geothermal heat, thermal energy discharged from industrial waste heat, and so on. The TRAB battery developed by Penn State University’s research team can recycle the low-grade heat that it continues to generate and use it for battery charging. Of course, there are other ways to recover waste heat, but TRAB batteries have achieved a very good balance between efficiency and cost. The lanthanum compound battery can only have a thermoelectric conversion efficiency of only 15-20%. While the fulvalene diruthenium-based battery has a much higher conversion efficiency, the cost is too high and the source is scarce.
According to researchers at Penn State University, the electrode materials of the new heat recovery battery system use a wide range of copper and ammonia sources, and the conversion efficiency reaches 29%. The low-grade heat energy in the ammonia compound can be used to heat the copper ions near the electrodes in the TRAB battery to react and charge the transport electrons. According to researchers, the power density of TRAB is about 60 watts per square meter, which is about 6-10 times that of other liquid thermoelectric power conversion systems. Researchers continue to focus on increasing power density, and in the future to achieve prototype production of scalable production for commercial applications.

Meat product lighting is a lighting solution specifically designed for the environment in which meat products are displayed and sold. It aims to highlight and accentuate the texture, color, and freshness of meat products by providing appropriate lighting to attract customer's attention and boost sales.
The design of meat display lighting takes into account several factors. The first is the meat case lighting intensity and color reproduction ability. Meat products need plenty of light to show off their true color and texture while highlighting freshness. By choosing lamps with a high color rendering index, you can ensure that meat products present a more realistic, natural color.
The second is the direction and Angle of lighting. Proper lighting direction and Angle can reduce shadows and reflections, so that the surface of the meat product is more evenly illuminated, avoiding unnecessary light background interference.
In addition, temperature control is also an important consideration for meat product lighting. Too high lighting temperatures may cause meat products to spoil or fade, so it is crucial to choose low-heat lighting.
Through reasonable lighting design of meat products, businesses can enhance the attractiveness of meat products, show their quality and freshness, and increase sales. At the same time, proper lighting also helps to enhance the comfort of the shopping environment and create a more pleasant shopping experience for customers. It is important to ensure the use of lamps that meet food safety standards and to choose the appropriate lighting scheme for different meat product types and display areas.
