Aquaculture, which relies on a balanced ecosystem of fish and plants, could be the future of urban farming
One of the biggest challenges to conquering world hunger is the shrinking availability of farmland. That is why farms of the future need to occupy less space, rely on fewer pesticides, and produce food that travels blocks, not miles, to combat climbing fuel costs.
The solution may be aquaponic farming, a revolutionary system of mini vertical farms where fish and plants live symbiotically.

Scientists may have created an affordable solution for those who live without electricity.
The invention is an artificial leaf, and it is powered by an advanced solar cell that mimics photosynthesis (the process green plants use to convert sunlight and water into energy.)

Last year we reported on the sustainability efforts of the 2010 Winter Olympics in Vancouver, which made the games the greenest yet. Vancouver was outfitted with solar panels, green roofs, and mechanisms to collect and recycle rainwater. Award medals were made from re-purposed electronic waste.
Now, Rio de Janeiro is aiming to create the first games with a zero-carbon footprint when it hosts the Summer Olympics in 2016.
To help the city achieve this goal, Swiss-based RAFAA Architecture and Design has proposed a Solar City Tower, which features a visually stunning energy-generating waterfall.

While this spacey-looking disk will not allow your car to time-travel, it might replace its internal combustion engine
Here’s a new approach to decreasing the environmental impact of cars: a new auto motor could make them 20 percent lighter and reduce emissions by 90 percent.
Michigan researchers have built a prototype of a disk-shaped shock wave generator that could replace the current internal combustion engine in cars. The generator is about the size of a saucepan and does not need a transmission, cooling system, or emissions regulation fluid, which would reduce the weight of a vehicle by 1,000 pounds.

Drivers often encounter wildlife along the road. But what if instead of the usual birds, deer, and squirrels, you could cruise alongside fish?
That vision is now a reality with the electric submarine EGO, which literally puts you face-to-face with underwater wildlife.
