For a moment the controversy on biofuels is topical in France.
In the range of biofuels can be found among the Esters (oils) Alcohols
(Ethanol / Methanol), CNG / LNG (Natural Gas for Vehicles). A small problem arose: For the processing of certain raw materials in biofuel and mass production you need energy. And this energy pollutes, being nuclear, for example. Since the goal is to create a means of transport more environmentally friendly, the auto industry has developed engines using biofuels. But while some manufacturers are trying to limit the damage of any solution, less hostile to the environment than oil, General Motors invented the Hummer fully recyclable at the end of 5 years dépollue without polluting.
Initially this car, designed for military usage is a symbol of pollution.
A huge 4x4 blocking three quarters of the route they are taking and which consumes about 11.8 L 100km, became the No. 1 green car.
The model Hummer O2 GM has 4 engines, which are actually four fuel cells, which consume hydrogen to finally do reject that of steam.
And while this car rolling dépollue: it is equipped with four batches of live algae, which absorb CO2 and turns it into oxygen (photosynthesis). Algae have a lifespan of about one year and can then be recycled to produce hydrogen. It remains to know where to look for that energy. In all cases, the concept is very futuristic.
The designers could have put these technologies to the services of a car series, definitely more marketable. We must have a taste for extravagance to fill appreciate this model. But it is a remarkable invention.
