On March 8th, NHK World broadcasted “Magnesium enegy cycle” in their news program.
You can watch this broadcast on the following page for a week since March 8th.
Rendering of desalination plant
Pegasos Electra developed “Pegasus desalination device” which uses
solar heat by a new method, as we mentioned in the article “A new
seawater-desalination technology which uses solar energy”.
Pegasos Electra is proposing a desalination plant for oversea clients.
The following photo is a redering of a desalination plant which
provides fresh water of 100 cubic meters/day. It consists of 10 units
of Pegasus desalination devices.
The plant draws water from the sea or a lake and warms up to 80-90 °C,
and makes it to distillated water. (We have to add some mineral to it
for agricultural water or drinkable water.)
Pegasus desalination plant works with solar-heat and consumes no electricity.
On Februaty 8th, a special topic of WBS, a TV news program in Japan, was “Magnesium”.
They introduce Magnesium as next-generation energy.
You can watch the special topic “Magnesium” from the following link. (Spoken in Japanese)
“The Maginesium Civilization” becomes iPhone app! You can download it from the following URL.
You see articles, YouTube movies and tweets of “The Magnesium Civilization” easily with this app.
November 24, 2009 – NEDO (Geothermal Energy Development Department) announced that SAITEC (Saitama Industrial Technology Center) developed positive electrode material for magnesium-ion secondary battery. You can read the press release here (written in Japanese).
The following is quotation from the press release (tranlated by MgCiv staff).
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:
An article “An economical “Solar-pumped laser” produces ultra high temperature” shows that solar-pumped-laser realized ultrahigh-temperature which is impossible with simple concentration of sunlight.
The following movie is an experiment of solar-pumped-laser at Tokyo
Institute of Technology in January 2009. Output of laser was 50W. It can drill a hole on a 0.1mm-thick stainless plate easily.
The next movie shows deoxidation of magnesium oxide with
solar-pumped-laser. You will see the smoke from MgO at the instance
when the laser is correctly focused. The output is not enogh for commercial smelting, but deoxidation itself is possible.
