    Diesel através de luz, água e CO2?

    Uma empresa do estado de Massachusetts, EUA, diz que consegue produzir gasóleo/diesel a partir da luz do sol, água e CO2.


    The company, the aptly named ' Joule Unlimited ', is an organism "made" that secretes diesel fuel or ethanol when it comes into contact with sunlight, water and CO2.


    The company says the bacteria genetically manipulated so that the fuel on demand 'produces unprecedented quantities. This production can take place on a large and small scale, and could even complete "energy independence" could mean.


    An acre (0.4 hectare) can almost 70,000 liters of diesel per year and nearly 115,000 liters of ethanol yield, the company writes on its website.


    Oil industry on its head "Even if we only half right, will the world's largest industry - the oil and gas industry - on its head," says the CEO of Joule, Bill Sims against the Washington Post .


    "We make big claims, which we all now have to prove. And we pushed investors under the nose," he continues. "There is no reason why this technology the world could not change."


    Seeing is believing But not everyone is convinced. National Renewable Energy Laboratory researcher Philip Pienkos wonders whether the fuel produced is as easy as can be collected.


    Another researcher, Timothy Donohue, director of the Great Lakes Bioenergy Research Center at the University of Wisconsin-Madison, believes Joules his claim where do through large scale to produce.


    Sigh of relief for the earth Anyway, if the technique works on a large scale, this means that the dependence on petroleum and petroleum producing nations can take. Moreover, the oil giants may invest in the technology. Indeed, they have something to lose if the world switch to fuels that are made ​​in other ways.


    Moreover, the fuel can be reduced because the pressure on the ever dwindling oil reserves on earth can take. A further advantage is that the fuel is CO2-neutral. Incidentally captured residual CO2 are used by large industrial Installations for the production.


    A final advantage is that no appeal may be made ​​on biomass as is often the case with the production of other so-called 'renewable fuels' or biofuels. Agriculture can therefore its entire production to concentrate on foods.

    Sempre que há aumentos significativos nos combustíveis aparecem noticias destas. Se for possível e for verídico, alguém se encarregará de abafar para que não faça mossa ao monopólio do crude....

      Joule Unlimited Technologies Inc. won the Silver in this year's Wall Street Journal Technology Innovation Awards for developing a more efficient technique for producing biofuel.

      The Cambridge, Mass.-based company has created genetically engineered micro-organisms that secrete ethanol, diesel fuel and other hydrocarbons from water, sunlight and carbon dioxide. The use of these patented organisms eliminates some of the costly processing steps needed to turn plants into motor fuel.
      "The technology has the exciting potential to significantly transform the economics of the biofuel industry," says Kenny Tang, founder and chief executive of Oxbridge Weather Capital and an Innovation Awards judge.
      Traditional biofuels derived from farm products such as corn and sugar cane have come under fire for using up resources that otherwise could be used for food. So researchers began looking to other materials—plants such as switchgrass or jatropha and micro-organisms such as algae—to produce the next generation of biofuels.
      Joule took a different path. It uses genetically modified strains of cyanobacteria, which are water-based organisms that make their food through photosynthesis. The organisms, created by a scientific team led by Joule co-founder Noubar Afeyan, can be tweaked to produce different fuels—one form can produce simple ethanol, while another generates more-complex diesel molecules.
      While regular algae has to be harvested and processed to squeeze out hydrocarbons, Joule's cyanobacteria release fuels continuously.

      Joule's other innovation is its SolarConverter bioreactor, a system of closed tanks that look like solar panels, where the organisms grow and release their fuels. Designed to maximize the amount of sunlight that reaches each organism, the tanks mix the cyanobacteria colonies with water laced with micronutrients and piped-in carbon dioxide. Liquid fuels are separated from the water and piped to nearby tanks for storage.
      Joule says its systems could produce 15,000 gallons of diesel and 25,000 gallons of ethanol a year on an acre of land, for as little as $20 per barrel-equivalent of diesel and 60 cents per gallon of ethanol.
      Since 2010, the company has been operating a pilot plant in Leander, Texas, where it is testing ethanol production. It plans to break ground this month on a larger-scale demonstration facility in New Mexico, with a goal of beginning commercial production by late 2012 or early 2013.

      Será... huummm, a ver vamos... as reações dos lobbys do petróleo.

        De bactérias não percebo nada, mas "luz, água e CO2" é tudo o que uma planta necessita para realizar fotossíntese, e podes produzir diesel a partir de óleos vegetais. Logo, não dá muita admiração.

          Já houveram muitas notícias destas, e produzir combustíveis biológicos não é novidade nenhuma.

          A dificuldade sempre foi, e continua a ser, produzir nas quantidades necessárias. A ver vamos, mas que é uma ideia que até me faz salivar, lá isso é. Motores Otto para sempre a combustível barato e acabadas as tretas do CO2, parece bom de mais para alguma vez ser verdade

            E a água? Poderá ser uma qualquer? Aí também há um problema...

              Vem um período e seca e o gasóleo aumentava logo xD

                Não sei as características deste organismo em particular, mas há uns tempos quando andavam a estudar algas precisamente para o mesmo efeito uma das vantagens era que podiam consumir água do mar.

                Dessa não se prevê escassez tão cedo
