Magnesium to Replace Uranium
Before the Fukushima Daiichi Nuclear Power Plant got into a big trouble due to an M9.0 earthquake and a 15-meter high subsequent tsunami in 2011, some scientists paid attention to magnesium for its huge potential as material to replace uranium as an electric power source.
Magnesium: Alternative Power Source

(PhysOrg.com) -- There is enough magnesium to meet the world's energy needs for the next 300,000 years, says Dr. Takashi Yabe of the Tokyo Institute of Technology.
Magnesium is abundant in the world; however the production of magnesium is neither cheap or clean. There are various ways of extracting magnesium, ranging from an electrolytic process to high temperature method called the Pidgeon process.
Dr. Yabe has devised a high temperature solution by concentrating solar collectors and a solar-pump laser to reach a temperature of 3,700 degrees centigrade. This high heat method is used to burn magnesium oxide extracted from seawater. The solar-pumped laser is necessary to help obtain this high temperature because concentrated solar energy alone would not be enough to generate 3,700 degrees C.
Engineers at MagPower have developed a metal-air cell that uses water and ambient air to react with a magnesium anode, to generate electricity. A magnesium based version of the lithium-ion rechargeable cell has been created by Dr. Doron Aurbach at Bar-Ilan University in Israel.
Magnesium is highly reactive and stores a lot of energy. Researchers are now devising ways to extract energy from magnesium in a more controlled method.In terms of prevention of global warming or suppression of CO2 generation, the magnesium-based electricity generation is advantageous.

The Magnesium Civilization
Alternative new source of energy to oil
We can burn hydrogen which is generated from magnesium and water. The reaction between magnesium and water also generates heat. Through clever use of this heat, the hydrogen generated from the reaction can be burned to produce high-temperature, high-pressure steam. This steam can then be used to rotate turbine to obtain mechanical power, or it can be used for electrical power generation.In comparison with lithium-ion batteries, magnesium-based batteries look more efficient while magnesium is less expensive.
In this case, the amount of heat generated from 1kg of magnesium is 25 Mega Joules including the heat generated by burning hydrogen. Coal, on the other hand, generates 30 Mega Joules, which is slightly higher than that from magnesium. However, there is nothing useful remaining after coal is burned; it is not easy to dispose of cinder, and a large amount of carbon dioxide (CO₂) is produced as coal burns.
On the other hand, magnesium oxide, which is produced as magnesium burns (reacts with oxygen), can be recycled to obtain magnesium. The only substances that are produced through burning magnesium are magnesium oxide and water (generated through burning hydrogen) and there is no carbon dioxide emission. There may be a time in the future when magnesium is burned instead of coal at electrical power generation plants.

These properties make our fuel cells extremely low-cost to produce; magnesium is 100 less expensive than lithium, the key ingredient in lithium-ion batteries, now the dominant player in fuel cell markets.
The lightness also makes magnesium-powered fuel cells highly portable — and natural choices for applications where reduced weight is a benefit.
Magnesium also has tremendous untapped potential for high-energy generation potential. Aquapower has already developed and tested low-cost magnesium energy cells with power output doubling that of lithium ion batteries.
Specific power is the battery’s ability to deliver power in watts per kilogram (Wh/kg).
Magnesium cell: 420 watt hours/kg
Lithium Ion battery: 200 watt hours/kg

There are 1800 trillion tons of magnesium in the sea water covering the earth. This amount is equivalent to 100,000 years of consumption of crude oil. Magnesium is taken from the sea to be refined. And it is burnt in a power generation plant where magnesium oxide is output along with electricity. This magnesium oxide undergoes application of a solar-pumped laser, resulting in conversion from magnesium oxide to pure magnesium. Then this recycled magnesium goes into the same cycle for power generation and application of a laser as the figure below shows.
The point at issue is that we don't need to use uranium for electricity generation. We must stop using dangerous uranium but start using environmentally-friendly magnesium.
