Elon Musk continues to announce that its Tesla it will improve the performance and cost of electric car batteries, a move similar to that of players in the global auto industry. But in Brazil, the key is for the electric car to remain “sexy, as it is electric, without generating particulate matter”. THE ethanol.
The millions of dollars spent in the world, not including the R $ 15 billion that the Volkswagen and three more partners announced for China in the coming years, will not eliminate the fact that the new generation four-wheel drive will be polluting in one way or another.
They are “sexy”, as the professor and scientist Gonçalo Pereira wrote in an article for the world’s affluent, but they won’t be powered by an ethanol cell in their batteries. The technology is in Brazil and, due to Pereira’s somewhat regretful tone, his best development is still stuck.
They do not pollute the exhaust, but the current and future trams, if Brazil is not as an important player, carry in their batteries ores that need to be mined. The emission of particles begins before they rotate.
And these fonts need to be loaded. And where does energy generation come from in most countries in the Northern Hemisphere? Of the thermoelectric plants, based on the burning of fossil fuel (oil or coal), continues Gonçalo Pereira, head of Unicamp’s Genomics and Bioenergy Laboratory.
Running in Brazil, an electric car parks on a charging totem, whose origin of electricity did not come from a thermoelectric plant (only in Roraima), but from a hydroelectric plant. Another thing with an environmental impact.
The ethanol battery, after the experience of the alcohol car in the 70s and the flex fuel later, has none of that, even less suffers from the “fallacy” that cane competes with food. Gonçalo Pereira defends the presence of 200 million hectares of degraded pastures. In Africa, there are 540 million hectares with potential for farming.
In addition, there is 2nd generation ethanol (2G), of which Pereira was one of the developers, who, produced from 100 million hectares, preferably with energy cane (more fibrous), supplies the entire world fleet of the Cycle Otto (combustion engines).
Together, millions of jobs.
Leaving the environmental focus and the supply of raw materials, which are not challenges, in the detailed demonstration of the teacher, but also slipping indirectly through these issues, there is the challenge of the “curse of 70%”. The compensation of ethanol is calculated in relation to the cost and energy parity with gasoline, without observing the long-term calculations for the health of the planet.
The Musk’s electric may have a performance slightly higher than that powered by the ethanol cell battery, but the up to 30 km with a liter that the Brazilian technology already known registers is of good size. Not to mention that development has not yet reached the top and with the advantages already mentioned.
If Brazil does not sleep on the spot and take advantage of the “exergy” of ethanol, or the maximum use of the working capacity of an energy source, according to the thermodynamics, we will have an “Electric alcohol”, reiterates the scientist, enthusiastic about what has been achieved by Brazil until now, in the academy-private sector partnership, in the development of this energy matrix.
