Socio-political and technological solutions

The first thing is pick up and run the redesign of cities. Urban transport for human activities is the parameter that contributes most to emissions of carbon dioxide. Reducing the causes and reasons for urban mobility will allow a drastic reduction of greenhouse gases. People should have no more than 10 -15 minute walk to everything they need to live, work, education, recreation, care etc.
At the same time we must support those searches directed to transform carbon dioxide into useful fuel.
Therefore we have to exploit the carbon content in CO2, transforming this greenhouse gas from problem to resource. The conversion of CO2 in fuel is not a dream but a real possibility that requires further studies. The research could allow to not enter, into the atmosphere, additional quantities of carbon dioxide emitted, by transforming that human activities in fuel useful. One of the problematic aspects of this gas is that it is highly stable. The chemical bonds of CO2, once trained, are extremely difficult to separate. The new technique, in the course of the trial, allows special catalysts to get this division and to create long chain molecules of carbon that can be easily converted into fuels.
The energy needed to separate this type of chemical bonds, even with catalysts, is very high. Maybe proceeding in two phases, first using sunlight (concentration plants) with a titanium catalyst that helps to separate the water molecules with the consequent release of free protons (hydrogen ions), electrons and oxygen gas. Then, in a second phase, using the free electrons to reduce CO2, which allows, through the use of catalysts platinum and palladium based, in carbon nanotubes, to link between their carbon atoms. If that could work, especially if the energy needed to replace solar and for both phases is that emitted by a laser powered by solar or wind power, who knows! We need more research… Imagine what would happen if the billions of tonnes of carbon dioxide emitted from power plants fired by fossil fuels were treated with this or other similar technology…we could return to hope. And this hope could increase for example if we think to those devices on which scientists are working in different research centres, that quickly could be able to capture the infrared energy emitted from Earth and transforming it into electricity. The material that exploits nanotechnology would be the first solar cells capable of administering the invisible infrared radiation of the sun. The researchers combined specially designed nanoparticles (so-called quantum dot) with a polymer, resulting in a plastic able to capture the infrared energy. Achieving this goal leads to predict future development of solar panels five times more efficient than possible with current technology. The rays of the sun reaching the earth's surface carry 10,000 times more energy than we consume.
If we could cover the 0.1 percent of the surface of the Earth with solar panels very efficient, we could theoretically replace all existing power plants with a source of clean and renewable energy. Among other things, the construction of nanotech devices that convert into electricity the infrared radiation emitted from the bodies at the environmental temperature or slightly above, would significantly increase the performance of technological tools commonly used by humans, from car to hair dryer, the clothes we dress, the pots with which we prepare food, and large equipment, such as medical diagnostic radiology equipment (TAC), could be reduced in size by camera. Increasing the efficiency and reducing the size of equipment means consume less energy and therefore burn less fossil fuels and then placing less carbon dioxide into the atmosphere.
Finally, to the technical interventions described above, we must add another one of socio-political nature, namely we must change the economic organization of the neo-liberal society, head of possible environmental disaster coming the next years. We must change the rules of world trade, reversing order in this historical phase, and economic value of protagonism should be a revolution that is proactive in the economy. This revolution must start from the citizen, the consumer who must move from passive object to active subject of the economic system, claiming and taking a central role in social life and production of each country. The policy, the current policy also voiced by democracies can not change the rules of WTO. It has a strength, but the Multinational corporations have more. How do? What to do? Today, the citizen consumer is alone at the mercy of everything and everyone. Multinationals and corporations merge among themselves to have fewer costs and increasing revenues. To achieve the goal of increasingly earning they are using any means, no matter if it reduces the world to a cloaca, a gas chamber, an increasingly hot oven. Result: the citizen consumer, in any corner of the planet he live, he have to pay the consequences, also suffering the adverse effects of climate change. So the planet can only be saved by him, the consumer. Question: What would happen if consumers were in groups of purchase? What would happen if, for example, U.S., Canadian, Italian, German, French, British, Spanish consumers were organize in buying groups, in "international of consumption"? It’s simple, they would alter the rules governing the functioning of markets and it especially could impact on the lifestyle because the next planetary disaster.
If we make in every of these nations this kind of group of purchase, there would be about five million consumers organized by country, by quarter, by city, by province, region, for several regions, and it would become a compact force of twenty million individuals (one average of 4 per family) able to modify and break the economic equilibrium established. On the economic function of buying groups of consumers, how it would change the economic rules, behaviour etc, I could write a treatise separately. The changes of the economic system are necessary, but they could need too much time. The buying groups of citizens consumers may instead build and operate quickly, because it is mature the conscience of so many individuals who feel tired to be passive objects of the economic system, tired of delegating their role of citizen. In many people there is an increasingly need of reappropriating of the right to civil and economic citizenship ..
