New discovery may allow scientists to make fuel from CO2 in the atmosphere

New discovery may allow scientists to make fuel from CO2 in the atmosphere | Sustainable Technologies | Scoop.it
(Phys.org) —Excess carbon dioxide in the Earth's atmosphere created by the widespread burning of fossil fuels is the major driving force of global climate change, and researchers the world over are looking for new ways to generate power that leaves...

Now, researchers at the University of Georgia have found a way to transform the carbon dioxide trapped in the atmosphere into useful industrial products. Their discovery may soon lead to the creation of biofuels made directly from the carbon dioxide in the air that is responsible for trapping the sun's rays and raising global temperatures.

World’s First Floating Wind-Current Turbine to be Installed Off Japanese Coast

Offshore wind farms and tidal energy facilities harness the power of the wind and the ocean – but why should we have separate turbines for each task? Offshore technology company Mitsui is developing a hybrid wind-current power generating system that combines a floating vertical-axis wind turbine with an underwater turbine that generates power from ocean currents. The clever apparatus would cut down on material waste, and it could produce twice as much energy as a conventional wind turbine
.

Renewable energy developers strive for improved efficiency in the solar, wind and hydro power industries – and the hybrid wind-current system effectively doubles the efficiency of a typical wind or ocean current turbine. Mitsui Ocean Development & Engineering Company says the system will provide cost-effective power generation while having very little impact on the environment.

The turbines will be large in scale; according to NHK News, the wind turbine will be 47 meters (154 feet), and the underwater portion will have a diameter of 15 meters (49 feet). The turbines will be tested off the coast of Japan later this year. If they work as well as advertised, each turbine could generate enough energy to power 300 households.

Urban Sustainability: The cities of the future will be grown, not built...

Urban Sustainability: The cities of the future will be grown, not built... | Sustainable Technologies | Scoop.it

The cities of the future will have waste-to-energy plants, not shopping malls or churches, at their center, according to urban designer Mitchell Joachim of Terreform ONE.

At DLD Cities in London, he said "cities have centers that celebrate previous centuries -- in Europe, the cities celebrated spirituality, with cathedrals. After some time, the cathedrals became downtown cores- and celebrations of capitalism and commercialism".

The cities of the future will celebrate "the belief of what keeps us alive" - or elements of the city that make our lives better.

 

Terreform ONE, a green design company in Brooklyn, explores biohacks for the ecological issues facing modern cities. For instance, the waste New York City produces every hour weighs as much as the Statue of Liberty - in the future that waste could be recompacted into building blocks, or recycled "bales". Looking beyond recycling, though, it would be even better to create a city which didn't produce waste in the first place...

That means growing thousands of homes -- building a new suburb could involve twisting, pruning and manipulating large trees into the frames of buildings. "There would be no difference between the home and nature -- it would be something that would be a positive addition to the ecology," explained Joachim.

Four Innovative Green Technologies That Just Might Save The World

Four Innovative Green Technologies That Just Might Save The World | Sustainable Technologies | Scoop.it

With many developing nations rapidly industrialising, dependent on fossil fuels as their energy mainstay, CO2 concentrations show no signs of abating. What will the ramifications be for food production and health moving forward in to the 21st century if weather patterns become even more hostile than the previous decade?

 

Fortunately, scientists and engineers are working on ways to neutralise emissions in to, or actively reduce the carbon content of the atmosphere until the time arises when we can transition to cleaner energy solutions. In the interim phase we find ourselves however, there are no perfect solutions, but there are technologies and techniques that can help combat the climate catastrophe that will be unleashed if CO2 concentrations continue to rise unchecked. Here a four such technologies…

This has some interesting ideas but I'm not so sure about  bio-engineering... that seems like it could backfire or get out of control and have unintended side-effects.

Stanford scientists develop new type of solar structure that cools buildings in full sunlight

Stanford scientists develop new type of solar structure that cools buildings in full sunlight | Sustainable Technologies | Scoop.it

Homes and buildings chilled without air conditioners. Car interiors that don't heat up in the summer sun. Tapping the frigid expanses of outer space to cool the planet. Science fiction, you say? Well, maybe not any more.
A team of researchers at Stanford has designed an entirely new form of cooling structure that cools even when the sun is shining. Such a structure could vastly improve the daylight cooling of buildings, cars and other structures by reflecting sunlight back into the chilly vacuum of space.

Awesome.
