Helium 3, scientists argue, could power clean fusion plants. Two fully-loaded Space Shuttle cargo bay's worth - about 40 tonnes worth - could power the United States for a year at the current rate of energy consumption. Pictured are the stages in getting the material back to Earth

     China ha expresado su interés, aunque aún tiene que esbozar el proyecto

El Helio 3, argumentan los científicos, podría alimentar plantas de fusión limpias. Dos transbordadores espaciales totalmente cargados  con un total de alrededor de 40 toneladas, podrían surtir a los Estados Unidos por un año, al ritmo actual de consumo de energía.

Ahora China está buscando minar la luna para explotar el raro isótopo de helio. Algunos científicos afirman que podría satisfacerse la demanda global de energía en el futuro, según un informe publicado en The Times.

El profesor Ouyang Ziyuan, científico jefe del Programa de Exploración Lunar chino, dijo recientemente, la luna es 'tan rica' en helio 3, que esto podría "resolver la demanda de energía de la humanidad por no menos de 10.000 años."

El helio 3 (He-3) es un isótopo no radiactivo de helio ligero con dos protones y un neutrón. Es abundante en el suelo de la luna al ser abandonado allí por los vientos solares. Su presencia es rara en la Tierra, pero es buscado para su uso en investigación de fusión nuclear. También se utiliza en escáneres de resonancia magnética y en sensores para detectar el plutonio de contrabando.

El helio 3 es abundante en el suelo de la Luna donde está en por lo menos 13 partes por mil millones en peso.

El gas, se estima, tiene un valor económico potencial de $ 3000 millones la tonelada, por lo que es económicamente viable considerar la minería de la luna.

Según los expertos en los EEUU, el costo total estimado para el desarrollo de la fusión, el desarrollo de cohetes y el inicio de las operaciones lunares sería de unos $ 20 mil millones en el decurso de dos décadas. Esto requeriría la minería una zona del tamaño de Washington, DC

El isótopo es tan raro en la Tierra porque la atmósfera y el campo magnético prevenir cualquier llegada de helio3 solar a la superficie.

La luna no tiene este problema, ya que no hay ni atmósfera ni campo magnético para evitar que el helio 3 se deposite en el suelo lunar.

Fabrizio Bozzato, un candidato doctoral en la Universidad de Tamkan en Taiwán, escribió en la World Security Network que el helio 3 puede extraerse mediante calentamiento del polvo lunar a alrededor de 600 ° C, antes de traerlo de vuelta a la Tierra.

Mientras que China ha expresado su interés, aún tiene que esbozar planes concretos sobre cómo explotar helio en la luna.
La perspectiva, sin embargo, plantea la controvertida cuestión sobre quién es dueño de nuestro satélite.

El Tratado del Espacio Exterior de las Naciones Unidas, firmado por China, sugiere que los recursos lunares son para toda la humanidad.
China, tiene la esperanza de algún día minar helio 3 de la luna. Los escenarios suena a ciencia ficción, y ha sido representado en Hollywood a través de películas como el éxito de taquilla Armageddon 1998 protagonizada por Bruce Willis

The lunar dirt brought back by mankind's first moonwalkers contained an abundance of titanium, platinum and other valuable minerals.

But our satellite also contains a substance that could be of even greater use to civilisation – one that could revolutionise energy production.

It's called helium 3 and has been dumped on the moon in vast quantities by solar wind

Now China is looking to mine the moon for the rare helium isotope that some scientists claim could meet global energy demand far into the future, according to a report in The Times.

Professor Ouyang Ziyuan, the chief scientist of the Chinese Lunar Exploration Program, recently said, the moon is 'so rich' in helium 3, that this could 'solve humanity's energy demand for around 10,000 years at least.'


Helium 3, scientists argue, could power clean fusion plants. It is nonradioactive and a very little goes a very long way.

For instance, two fully-loaded Space Shuttle cargo bay’s worth - about 40 tonnes worth - could power the United States for a year at the current rate of energy consumption.

WHAT IS HELIUM 3?

Helium 3 (He-3) is a light, non-radioactive isotope of helium with two protons and one neutron.

Its presence is rare on Earth, but it is sought after for use in nuclear fusion research. It is also used in MRI scanners and in sensors to detect smuggled plutonium.

Helium 3 is abundant in the moon's soil by at least 13 parts per billion (ppb) by weight.

The gas, he estimates, has a potential economic value of $3 billion (£1.78 billion) a tonne, making it economically viable to consider mining from the moon.

According to experts in the U.S., the total estimated cost for fusion development, rocket development and starting lunar operations would be about $20 billion (£11.8 billion) over two decades.

Two fully-loaded Space Shuttle cargo bay’s worth - about 40 tonnes worth - could power the United States for a year at the current rate of energy consumption.

This would require mining an areas the size of Washington, D.C.

The isotope is so rare on the Earth because our atmosphere and magnetic field prevent any of the solar helium 3 from arriving on the surface.

The moon doesn't have this problem as there is nothing to prevent helium 3 being absorbed by the lunar soil.

Fabrizio Bozzato, a doctoral candidate at the University of Tamkan in Taiwan, recently wrote in World Security Network that helium 3 could be extracted by heating the lunar dust to around 600°C, before bringing it back to the Earth.

While China has expressed an interest, it has yet to outline concrete plans about how it would mine the moon for helium.

The prospect, however, raises the controversial issue about who owns our satellite.

The United Nations Outer Space Treaty, signed by China, suggests that lunar resources are for all mankind.
China is hoping to someday mine helium 3 from the moon. The scenarios sounds like science fiction, and has been depicted in Hollywood through films such as the 1998 blockbuster Armageddon starring Bruce Willis

Private groups are also interested in using fuel from the moon by possibly water rather than helium 3

However, legal experts claim the language is ambiguous enough to allow for commercial exploitation of the moon.

In a recent paper, Mr Bozzato said: 'China appears determined to make [lunar mining] a reality of tomorrow.

'China maintains its lunar mining would be for the benefit of all humanity,' he added.

'However, given the absence of willful competitors, it is also speculated that the Chinese intend to establish a helium 3 monopoly.'

Private enterprise is also interested in using fuel from the moon – although possibly by extracting water rather than helium 3.

The Shackleton Energy company envisages providing propellant for missions throughout the solar system using lunar water.

Some teams vying for the Google Lunar X-Prize also see mining as an ultimate goal of their landers. ESA has also considered using the Moon to help missions farther into the Solar System.

Arguments have also been made for mining Helium-3 from Jupiter, where it is much more abundant – it would need to be given the distances involved.

Extracting the molecule from Jupiter would also be a less power-hungry process.

Todo esto es indesligable de la política y por ello esta también se observa. Ecology, social and environmental sustainability, emphasis on conservation of rivers and ecosystems, denounces impact of megaprojects. All this is inseparable from politics, for it, the politics is also evaluated.
