Professor Yabe of Tokyo Tech is heading the development of a process that combines magnesium and water to produce high energy steam and hydrogen, which is burned to produce additional high energy steam to power an engine with no harmful emissions. The magnesium oxide by-product is reduced back to magnesium through a solar powered laser process to be reused


The brain child of Professor Takashi Yabe of Tokyo Institute of Technology, now also under development by Mitsubishi Corporation, the Magnesium Energy Cycle uses water and the common metallic element Magnesium to create pollution-free power.

According to a Wikipedia entry, the chemical reaction between magnesium (in a powder form) and water at a room temperature produces high energy steam and hydrogen. The hydrogen is burned at the same time to produce additional high energy steam. These two steam sources power the engine. The energy cycle produces no carbon dioxide or other harmful emissions. The only by-products of this reaction are water and magnesium oxide. The magnesium (a common metallic element) is separated from the oxide through a solar powered laser process (whose development is already well advanced) and is reused over and over again as fuel.

Despite the prototype's small dimensions (approx. 5 cm in diameter and 13.5 cm in height), the engine can generate a heat output of several tens of kW from which power is obtained. The engine is aimed to be used in cogeneration, automobiles, ships and many other areas. Further research is planned with the aim of commercialization in the next three years.

Hi Sterling,

I noticed that the articles on PESWiki concerning the MAGIC engine and related technologies being developed by Takashi Yabe in Tokyo are dated from 2006, and they suggest that commercial availability would be three years from that date, ie - now. However, my internet searches couldn't locate any more recent information or announcements, so I contacted Mr Takashi Yabe himself directly to ask. He very kindly explained the situation as follows:

At present (November 2009), the project currently has no working relationship with Mitsubishi, but they have been working with other Japanese companies. He informed me that the most information / announcements concerning ongoing developments is not available in English, except for that published in scientific journals. He said the project is currently at the business stage and we (the west) should hear of progress in several media outlets within the coming year. They are already selling a desalination plant based on the technology, and are able to cut steel by sunlight-powered laser. He also mentioned that Toyota Motor Cars announced in July 2008 that the "ultimate electric car will run with a metal fuel battery, which is 7 times more effective than a Lithium-ion battery".

He also pointed me to a link on the Time Magazine website concerning his technology, he has been named 2009 "Hero of the Environment" in the Scientists & Innovators category: http://www.time.com/time/specials/packages/0,28757,1924149,00.html

Takashi Yabe has also written a book entitled "Magnesium Civilisation", which is currently being released and will be available in Japanese from December 16th 2009. It is hoped it will be translated into English in the near future.

I asked if I could send this information to you for publication on PESWiki, and he agreed, so please feel free to add this information to the site.

"MAGIC " (MAGnesium Injection Cycle) engine

Quoting from http://www.mitsubishi.com/mpac/e/monitor/back/0608/green.html, dated Aug/Sept 2006

Mitsubishi Corporation (MC) and the Tokyo Institute of Technology (Tokyo Tech) have recently made a significant announcement—the completion of a first prototype CO2-free engine called the Magnesium Injection Cycle (MAGIC) engine. Although still at the experimental stage, this joint project, initiated in 2005, has developed a prototype that has successfully worked without the need for fossil fuels.

Power is generated by the chemical reaction between magnesium and water, which produces high-power steam and hydrogen. The hydrogen is burned at the same time to produce more high-power steam, and the two steam sources power the engine. The new technology produces no carbon dioxide or other harmful emissions and the only by-products from this reaction are water and magnesium oxide.

The magnesium is separated from the oxide through a solar-powered laser process and is reused over and over again as fuel. This clean energy cycle, which is supported by solar power, has the potential to steer society away from its dependence on fossil fuels, and could bring about a paradigm shift in the way future energy needs are met.

The new MAGIC technology is very versatile, and has potential for use in cogeneration, automobiles, ships and many other areas. MC and the Tokyo Tech team believes it will take another three years of further research and experimentation before it is launched for commercial use.

Magnesium

Magnesium, a light, shiny metal, is the ninth-most common element in the universe, and makes up 2 percent of the earth's crust and is the third-most common element dissolved in seawater. Professor Yabe says: "Magnesium can save the world!"
