Sao Paulo, Oct 24 (EFE).- Gol airlines said one of its planes covered the Sao Paulo-Brasilia route using biofuel, a first for Brazil's aviation industry.
Using biofuel in aviation would be a tremendous way to reduce emissions and fuel needs, given the high consumption of global aviation. An experiment in this area, by a developing country and with biokerosene, derived from biomass, is hopefully a good way to start.
Scientists have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into biofuels.
Cellulosic is hailed by many as the future. But making it happen is incredibly hard. To come up with a way to not only eliminate acetic acid but also make it so that simultaneously more ethanol is produced is tremendous. It closes the cycle of production of biofuels, making them less wasteful, more feasible and more profitable. It's tremendous work.
The 2 x 4 from NTS Works is arguably the most efficient motorized vehicle on the planet. Neal Saiki and the 2 x 4 “You can go 10,000 miles on $30 of electricity,” explains inventor and company founder Neal Saiki.
Efficiency is innovation, as far we are concerned. And this bike and its improvements in electricity consumption are amazing. We hope to see them around...
Previously the idea of cleaning up the world’s oceans with their vast accumulations of disposed plastic material was considered an impossibility.
We're a little torn here: the idea - and idealism - behind this invention is beautiful. And to be able to remove all plastic 'surfing' the ocean would be outstanding. But questions arise: the viability, who is responsible for ocean clean-up and who would invest in it - and who would keep the profit... and can you get someone to seriously evaluate the feasibility of the invention? Does anyone with enough money care enough/is willing to do it?
The Redox Power System will use technology to produce energy more efficiently for far less money.
Despite finding the image a little silly, I think that, should this be as promising as it sounds, in terms of energy density and temperature, it'd be astounding. Hopefully, these technologies will develop as fast as possible so we can start having viable alternatives.
An electric bus that charges its batteries while driving (rather than while sitting idle in a charging station) is no longer science fiction.
Electric buses not longer need to sit still for a recharge: researchers at Korea’s Advanced Institute of Science and Technology (KAIST) created specialized electric cables that are designed to power the buses on the move. The technology, called Shaped Magnetic Field in Resonance sends electromagnetic fields created by cables buried in the asphalt to buses but not cars, being able to recognize which vehicles can and cannot accept the electric charge. If it's replicable, it could be a great alternative for green public transportation.
We're headed for historic milestones in solar power production. These will change the face of human civilization.
This graph, along with the last scoop, shows that change in energy pratices is possible and not all that expensive. Indeed like any technology, massification reduces the price, thus making it more readibly available.
A new type of two-layer solar cell could power our devices and buildings while remaining transparent.
The solar cell is being improved by UCLA so as to reach commercial viability. With so many new options and technologies coming along every day, shouldn't we be able to at least change the energy outlook a little by 2040?
Cutting-edge technology going on trial in Leighton Buzzard could save UK £3bn a year and spread around the world
This is great news for green energy proponents. If indeed a battery can store energy for release over long periods, compensating for the production gaps in wind and solar, than many of the arguments - and perhaps the biggest one - against green would fall to pieces.
A mosquito can detect the carbon dioxide emanating from a prospective meal from hundreds of feet away. The Kite Patch, a small, non-toxic sticker that you place on your clothing, can jam a mosquito's CO2 radar.
It seems like a brilliant idea and very important at that, for all the diseases it will potentially secure against such as malaria. But we're a bit fuzzy on the actual impact it has on the mosquitoes: don't get us wrong, we hate interacting with them as much as next person but are incredibly important for our ecossytems and should not be eliminated. So if the promise of just keeping them away is just that, this seems amazing.
Now that's smart cement. Dutch scientists are heralding the results of an experimental pavement they say was able to cut air pollution by wide margins.
Not sure whether to include this in the Scientific & Tech Innovation topic or Sustainable Development one but it has the best of both worlds, so I'll be mentioned in both. This cement with the Volvo wireless electric charging roads, are a dream!
Fuel cell converts gas into heat and electricity without producing carbon emissions
There has been great talk of the potential of fuel cells and we have scooped some articles here about it. But none as descriptive as this: no nortigen oxide, sulfur dioxide or particulate matter pollution. In addition to that it emits 38% less carbon dioxide than electrivity from the grid and heat from gas-fired boilers, in all reducing fuel costs and the carbon footprint of the building by 40%, compared to conventional electricity and heat use. Although the name of the fuel cell is not mentioned, it sounds like they might be a path forward - or at least a great stop-gap option.
Escherichia coli can cause serious food poisoning but Korean scientists have come up with a more helpful use for the sometimes-deadly bacteria: producing gasoline.
Testing E. Coli to produce biofuel is not the newest of news. But to be able to produce chemically-equivalent gasoline from it is an advance, despite slow and with small amounts, that might be very interesting to our future. Let's see what comes of this.
The future of giant space structures may lie in the 3D-printing hands of robotic spiders.
This sounds far too sci-fi but it is the 21st century and if they're working on it, we'll be waiting to see what comes of it - not so much because of the tech (though it will be delightful to see) but because it can help with serious fuel consumption for space tech, which would be great.

It's the first time we've come across information regarding an attempt at the use of biofuels by aviation companies. They are very commendable but we look forward to seeing which biofuels they intend to use, since the use of first generation biofuels in aviation would be terrible in terms of competition with agriculture and landgrab. Also, I do't understand why is the Russia partnership news when the others (Europe, Latin America, etc) have failed to get any attention.
Image via Wikipedia For the past several months, a friend of mine has been telling me about the potentially game-changing implications of an obscure (at least to me) metal named Thorium after the Norse god of thunder, Thor.
We are just as curious as this writer to see what will come of this, keeping in mind that it takes a lot of time and lot of experimenting to know how effective something truly is.
In an effort to raise awareness about the lack of access to clean water, this team of engineers built a machine that converts sweat into drinking water.
We couldn't say it better than the writers themselves, so here it goes: "From fog dew collectors to billboards that harvest rain, the unfolding global water crisis has translated into innovative ideas for conserving water -- or finding clean water in unexpected places, such as human armpits. Partnering with UNICEF and Swedish advertising agency Deportivo, a team of engineers led by designer Andreas Hammar have created a contraption that actually converts human sweat into clean, distilled drinking water." So much effort and money is going into creative and ecologial solutions, that we can't believe that a way without fossil fuels can't be found.
This has been independently certified by the Yangzhou Opto-Electrical Products Testing Institute, and the company claims that it "eclipses that of all previously certified industrial size multi-Si solar cells.
A Chinese company has developed a new multi-crystalline silicon PV cell that reaches a 18.3% efficiency with a 15.6 square centimetre cell. The evolution in renewables is becoming so present, that it has to be not only part of the solution but also part of the transition.
Not a bad start considering that Tesla is selling all the EVs it makes and is supply constrained, and that these competitors are all large companies that have been around for decades, making relatively conventional cars, while Tesla is a young...
Tesla proves that technology and science for green can have a footing in the mainstream market. Here's to hoping Tesla starts a not-too-long transition to very ecological transportation.

This robot runs along on what looks like a Lilliputian monorail to adjust the panels so they’re getting maximum sun exposure. Only introduced last September, the company is making improvements already.
This QBotix scoop is another one that would fit into both our topics (which is great, since to use tech for sustainability is brilliant). Introduced last year, Qbotix is a little dual-axis robot that manages the sun panels so as to get maximum exposure, with up to more 15% energy than a single-axis system delivers. But the company is already building for bigger-scale than its 200kw, with $12.5million raised from existing investors.
Concentrating the sun's ray onto solar photovoltaic (PV) modules requires walking the fine line between optimizing power output and not literally melting your very expensive super-high-efficiency solar cells.
Today is a great day for stories that fit in both our topics, which is always great news. These new modules can keep up to 80% of the captured energy, with a single collector producing 25kw of electricity.
