In addition, he flew an airplane with a laser and made a proposal for a magnesium circulation society. Calculation by CIP method The ship, the sea, and the air are calculated at the same time. This was done by Professor Takizawa of Waseda University during his doctoral course at Yabe Laboratory. Fly a microplane with a laser Applied Physics Letters 2002 It was reported on Nature and the New York Times. Leads to laser refining

Environment Mg Refinement EV Desalination Yabe Battery Emergency Sunlight Laser Mg Engine Solar Energy cannot be Alternative Eneregy We frequently discuss the average value, however, it is dangerous in solar energy. For example, an example below shows average sunshine to be 4 hours / day but we meet 4 days of 0 sunshine. In this case, we have to store the solar energy for 4 days. The battery for 4 days is 11 billion kWh and hardly realized. Hydrogen, Storage Problem Energy volume density of hydrogen is extremely smaller by an order of magnitude than gasoline even at high pressure. This means it needs 10 time larger volume to transport. At 700 atmospheric pressure, 7000 tonnes is imposed on 1 m2_cc781905-5cde-3194-bb3b -136bad5cf58d_ surface, then it is impossible to make a large container. Including the weight of container, Energy density / kg becomes extremely large. Storing liquid hydrogen needs -253 degree, electric power for this purpose becomes enormous. In order to avoid, thick heat insulation wall is required. If the tank is fully filled, it might be better but small amount remained in the tank should be serious problem because heat income from the wall stays the same but heat receiving hydrogen volume becomes small. Getting hydrogen from methane etc. emits CO2. Mg Engine Mg Refinement EV Desalination Cellphone Charger Emergency

マグネシウムを石炭・石油の代わりに燃やして、火力発電をを作る Magnesium combustion thermal power plant Magnesium generates almost the same amount of heat as coal and burns. When burning, it reacts with oxygen in the water. When oxygen is sprayed on the generated hydrogen, it becomes water, so only high-temperature steam comes out. It just generates electricity as a steam turbine. At this time, only water is generated, and no greenhouse gas is emitted. It's just clean energy. This dream power cycle, which can also recycle spent fuel, was published in a world-famous magazine in 2006. Magnesium thermal power plant concept So what about a specific magnesium power plant? From the left, a mixture of water and magnesium is injected. Oxygen is injected from the top and hydrogen becomes water. From the right, only steam is ejected to turn the turbine and generate electricity. By the way, what about magnesium and water? Magnesium at this time is a thin piece of about 1 cm. Water and magnesium are together, but not dissolved, This injection experiment is also introduced below. Fuel supply experiment This is an experiment in which a mixture of magnesium flakes and water is supplied from the top of the combustion chamber. If you close the lower valve and open the upper valve, a certain amount of fuel will flow in during this time, and after closing the upper valve, open the lower valve and the fuel will enter the combustion chamber. You can see the lamp lit by the generator in the center of the wheel.

XPRIZE Team "Zero Waste Disposal Desalination" Desalination device without high salinity discharge 　　The population is expected to reach 9.73 billion by 2050, which will require 2.2 trillion tons of new water per year. Current equipment such as reverse osmosis desalination systems are forced to release seawater with high salinity, causing serious environmental damage in the surrounding waters. 　　We patented a device that produces only pure water and recovers substances contained in seawater as solids, and succeeded in manufacturing a testing machine. The device operates at low temperatures below the boiling point, works with solar water heaters and various waste heats, and is an environmentally friendly device. Four Major Technologies of Yabe Desalination 1. Evaporation at Low Temperature(60-80degree) and Atmospheric Pressure 2. No Membrane used 3. Ultra-multistage in one stage container 4. Reuse latent heat Evaporation at Low Temperature and Atmospheric Pressure Since the multi-stage flush method uses boiling, it is necessary to change the atmospheric pressure in order to achieve different boiling temperatures.In contract, evaporation can occur at atmospheric pressure and at any low temperature like steam from coffee cup. But the evaporation rate in this case is very slow. In order to accelerate the evaporation rate, we need to increase the surface area of water-vapor interface making fine droplets.In 1974, Yabe proposed to use the rotating drum to making fine droplets and the droplet size is inversely proportional to rotating speed. By properly designed the form of propeller, the size of mists becomes extremely fine as shown in the video below. Ultra-multistage in one stage container Reuse latent heat The latent heat of evaporation is enormous but the latent heat of condensation is the same amount. If we can use the latter to heat the evaporation, required energy for desalination becomes very small. However, heat cannot be transported from low temperature to high temperature. To overcome this difficulty, multi-stage method has been invented. Yabe found that the circulating pure water can be an alternative to this technique. The green arrows represent the circulating water. On the top part of the figure, circulating water gains energy from heat exchanger in condensation, On the bottom of the figure, circulation water gives this energy to seawater for evaporation. How to remove ingredients like salt If seawater continues to circulate inside the device, salt precipitates when salinity exceeds 20%. Only thing we must do is to simply scoop the salt mechanically. Fortunately salt appears only in the red circled part of the device, Less Energy Consumption than MVR (Mechanical Vapor Recompression) Since a part of seawater is evaporated to pure water during this cycle, the same amount of new cold seawater should be introduced to the system, If the temperature of seawater is 20 degree centigrade, it must be raised to 40 degree but required energy is 4.2x20 J/g while latent heat of evaporation is 2400 J/g. Then required energy of this system will be 1/30 of latent heat. Then this system works economically with solar heating etc. Prototype device - Salt removed completely How to construct large system YouTube Video YouTube Video Experiment in Taizou, China December 10, 2019 Portable device capable of 1 Litter / hour carried from Japan . Polluted (Left) to Pure Water (Right) Improve Existing Facility Ordinary desalination plant like RO (Reverse Osmosis) exhausts high-salinity and polluted sea water back to ocean. In order to solve this problem, we propose to use our desalination device. This plan is named "Remora Strategy". In RO, 3 seawater input is converted to 1 pure In addition, production of pure water increased by 3 times. Out device should convert this exhaust to pure water, solving pollution problem. In addition, production of pure water increased by 3 times.
