FAQ
Question:
“Magnesium Bunmeiron (Magnesium Civilization)” describes that equipment and running cost of “Pegasus desalination device” is much lower than other methods such as reverse osmotic membrane.
However, a practical desalination plant will be much bigger than a pilot machine. Can it put out the assumed performance with the practical plant, even if you can get a good result with the pilot machine?
Answer:
Question:
Magnesium reacts with water or oxygen easily. Isn’t it dangerous?
In addition, can metal magnesium be stored for a long term because it is easily oxydized?
Answer:
Question:
Solar-pumped laser medium contains various rare metals such as
Chromium, Neodymium, Yttrium.
Struggles for these rare metals become fierce wordwide. Are there sufficient resources for laser medium?
Answer:
Question:
Is running cost of a solar-pumped-laser device free?
Don’t you need energy for sun-autoguider or cleaning cost of a Fresnel lens (especially in a desert) ?
Answer:
Question:
How much is conversion efficiency of magnesium with solar-pumped-laser smelting?

The current “energy currency” is electricity. The electricity can be distributed through power grids and it can be used for many purposes such as generation of heat, motion and lighting. Hydrogen was generally considered to be a possible energy currency in the future. But what our group is considering as the next-generation energy currency is metal, which is the same as the monetary currency. Namely, it is magnesium, which is lighter than aluminum with white silver glitter.
Seawater contains abundant Magnesium, approximately 1,800 trillion tons. Magnesium can be smelted with “solar-pumped laser” and used for fuel of automobiles and powerplants. Solar-pumped laser regenerates metal Magnesium from generated Magnesium oxide.
A low-cost desalination device with solar-power is used to extract Magnesium from seawater. It will be a promising solution for the global water shortage.
