Scientists at the German Aerospace Center (DLR) are testing to generate hydrogen fuel, a potential green energy source, by using a large array of light.
This is the "Synlight" project whose purpose is to use the power of the sun to split water molecules into hydrogen and oxygen atoms. Because it burns without releasing any hydrogen emitted by greenhouse gases, it can be used as a green fuel source. But the problem is that hydrogen doesn't happen naturally on the earth, you have to break the water and get it.
The Synlight array consists of a 149-inch short arc lamp, commonly used as a movie spotlight, placed in a honeycomb pattern. The amount of space in that space is approximately 10,000 times that of natural sunlight, producing temperatures as high as 3,500 degrees Celsius.
The key to all this is to figure out how to focus on the natural sunlight and divide the water most effectively. We obviously can't use huge light bulb arrays like Synlight, which cost $3.8 million. However, the almost unlimited supply of energy generated by the sun just needs to be used. This is a similar concept to a modern solar thermal power plant that will produce hydrogen fuel.
The nose clip, as the name suggests, is a thin rubber strip used inside the mask to fix the mask on the bridge of the nose. Therefore, the nose clips are also called the full plastic nose clip-the bridge of the nose-the line of the bridge of the nose.
The nose clip of the all-plastic mask is made of polyolefin resin. Like a metal twist tie, it can bend and deform with external force, and it will not rebound after losing the external force. It can maintain the excellent performance of the existing shape. It can be similar to non-woven materials. It melts together and plays the role of fixing the mask on the bridge of the nose.
