Recently, the nano-diamond thermal energy utilization technology researched by the University of Bristol in the United Kingdom has made important progress and has been reviewed and funded by the UK Engineering Physics Scientific Research Council (EPSRC). This technology marks another new use of diamond, the world's toughest material, for energy efficient use. Professor Dr Neil Fox of the University's Department of Chemistry successfully applied for a project fund of £951,947. The project name is “β-Enhanced Thermal Ion Energy Converter and Nuclear Battery Based on Nano-Diamond Electrodeâ€, which began in April 2013 for a period of 42 months.
Through a device called a thermionic energy converter, resources such as solar, geothermal and nuclear energy are converted into electrical energy. This technology was introduced as early as the 1950s to supply energy to spacecraft and nuclear reactors to extract energy. However, the use of materials to efficiently extract energy has always been a technical problem; if the technology breaks through the limits, it can provide up to 1200 °C of heat. In recent years, with the advent of nanodiamond technology, scientists at Bristol University may make it a reality.
The research project has two purposes:
First, by combining with plasma nanostructures, the superior properties of diamond in the thermionic converter are maximized, thereby maximizing the absorption of solar energy and ultimately converting it into electrical energy.
Second, study how the beta radiation produced by carbon 14 (C14) in radioactive graphite improves the performance of the thermionic diamond energy converter. If the C14 in the energy converter can be fully utilized, it will provide a more economical method for the treatment of radioactive graphite in the retired Magnox & AGR nuclear reactor in the UK. These materials can be used as a raw material for a new type of thermionic energy converter, called the "β-enhanced thermionic diamond converter" (BTDC).
The project plans to have an interdisciplinary professional research team: Tom and Peter from the Interface Analysis Center (IAC); Martin Cryan from the Department of Electrical Engineering; Flewitt from the Department of Physics; and Neil allan from the Department of Chemistry.
The study is expected to be applied in areas such as livelihood, military and space power generation. (Compiled from EPSRC grant for renewable energy project)
Motion Sensor Floodlight with aluminum heat sink material and design to prevent the LED smart floodlight motion sensor from overheating and ensure that the lifespan of the exterior motion flood light with socket can reach 50,000 hours. The motion sensor floodlight adopts an intelligent sensor. When someone passes through the sensing area, the outdoor motion sensor flood light will light up; when the person leaves the sensing area for a period of time or no one passes by, the light will not light up.
