Cambridge (USA), November 4, 2015 – Reduce the “fever” of the planet with diamond dust splash in the atmosphere. And ‘the hypothesis put forward in a study conducted by a group of climate experts of’ Harvard University , in Cambridge (Massachusetts), in the US, according to which with the nanoparticles Diamond sprayed in the sky would be able to reflect sunlight by counteracting the greenhouse effect and lowering, as well, the temperature of the planet.
Experts claim that the diamond dust is much more effective and environmentally friendly compared to aerosols of sulfates, for years now the central theme of the scientific debate on global warming and on climate change on Earth. These gases, in fact, should favor the reduction of temperature with a mechanism that mimics the effects of a volcanic eruption, but at the same time may trigger a series of negative consequences reacting with other substances present in the atmosphere.
For example, they produce sulfuric acid could damage the ozone layer around the Earth. In addition, absorbing light at specific wavelengths, may overheat the lower layers of the atmosphere, thus altering the circulation of winds and climate. Still, sulfates may diffuse the light on the surface of the Earth, causing an increase in plant growth and reducing the productivity of solar panels.
The solution of climate experts would be in a mix of diamond and aluminum It would help to overcome all the problems arising from the use of sulphates. Researchers claim that using two types of solid nanoparticles, aluminum and synthetic diamond, these would be more effective by 50%.
Even if this involves very high costs. Suffice it to say that the cost of the diamond powder is around $ 100 a kilo, and to cool the planet it would serve a huge amount. It is estimated a cost of several billion dollars a year if you wanted to realize the idea.
For the time being, given the high costs, experts are focusing on the use of nanoparticles of aluminum, the most studied, and therefore the same chimicamante more stable and secure, easier to manufacture and above all less expensive than diamond nanoparticles (although synthetic).
The results of the study were published in the journal Atmospheric Chemistry and Physics.
