Recycle Used Magnesium Fuel by Laser Mg Recycle Solar laser Laser refining of magnesium Applied Physics Letter 2006 Announcement The most poplar method for magnesium production today is the Pidgeon method. However, this method uses 10 kg of coal to produce 1 kg of magnesium. This does not allow magnesium to be an alternative energy source to coal. Professor Emeritus of Tokyo Institute of Technology Yabe proposed to convert natural energy into a laser for refining, achieving the same purity with much higher efficiency. Here's why the laser method is so good. Experiment to regenerate magnesium by laser Some people may think that using a laser for refining is too expensive. Actually, it is not expensive even at present. The price of semiconductor lasers will drop dramatically if they are mass-produced, so equipment costs will drop even more in the future.

非常用にどのようにマグネシウム電池が使用できるかの例を紹介 Contributing to a Magnesium Recycling Society magnesium battery For more information on mobile chargers 12V, 200W, 400Wh Right figure: When you finish using it, you can replace the fuel from the top and use it again. A 12V DC output magnesium battery (center) is converted to 100V AC using an inverter (lower right) to supply electricity to the TV. In the figure below, the lighting and the TV are operating at the same time. 12V, 150Wh

マグネシウムは火をつけても安全だという実験映像 Is magnesium safe? Speaking of magnesium, does it explode or ignite? Some people are worried. Yes, it's true when it's made into powder, but the powder explodes with flour, coal, or iron. Magnesium does not burn at all when it reaches a thickness of about 1 mm, even if you try to light it with a lighter. Watch the video below.

どのような環境問題が存在するかを指摘している Why is a Magnesium Recycling Society Necessary? Solar energy cannot be an alternative energy Many people often argue with the average value, but in the case of the sun, as shown below, the average value is 4 hours a day even if there is no sunshine for 4 days. However, it would be a problem without electricity for 4 days. You will need a storage battery to store these four days. This is a 10.8 billion kWh storage battery, which is not very feasible. Storage of hydrogen energy is a problem Hydrogen has a small volume density, and even at high pressure, it is nearly an order of magnitude smaller than gasoline as shown in the figure below. This is disadvantageous for transportation because the volume is an order of magnitude larger when transporting. As shown in the figure on the left below, with 700 atm of hydrogen, a weight of 7,000 tons is applied per 1 m square, making it impossible to make a large container. This also adds the weight of the container, which reduces the energy density per weight. To store it as liquid hydrogen, it needs to be cooled to -253 degrees Celsius, but the power is enormous. Therefore, it is necessary to refrigerate only with heat insulating material, but if the full tank contains hydrogen or if a small amount remains, the amount of heat to hydrogen per unit volume will increase, making it impossible to store for a long time. increase. For hydrogen storage alloys, etc., a method that does not use any energy for the storage and release of hydrogen has not been found at present . If hydrogen is extracted from hydrocarbons such as methane and methanol, CO2 will be emitted and it is meaningless. Energy currency I advocate the concept of energy currency . Until now, the energy currency has been fossil fuels. Is there a new currency that will create an energy cycle in the future? The annual consumption of fossil fuels is 10 billion tons, so if you don't always think about this, the discussion will be empty. We believe that this is the only equivalent of magnesium, which has 1800 trillion tons of resources. Mg power generation Mg regeneration EV Freshwater equipment Mobile charger Emergency battery
