Limbo self powered robot utilizes bacteria as a power source

Limbo self powered robot

Celebrating its 25th anniversary, Casabella has come up with a cleaning robot concept called the “Limbo” that makes use of Microbial Electrolysis, a process that utilizes bacteria as a power source, to power itself. Designed by Elliot Cohen, the cleaning robot harnesses energy from the bacteria bred in the waste that it gathers from your kitchen and other parts of home.

Bloom phytoplankton farm filters salty water into fresh water and soaks up carbon dioxide

Bloom Floating Phytoplankton Farm

With limiting space on earth due to fast growing population, scientist and researchers are exploring new possibilities where we can live and work to sustain our lives. Addressing the issue, Paris-based Sitbon Architectes has come up with a futuristic semi-submersible farm called the “Bloom” where inhabitants can grow phytoplankton-microscopic marine organisms which helps in eliminating carbon dioxide from the environment, other than providing shelter to the people.

EWICON prototype wind energy generator has no spinning blades

bladeless wind turbine_1

One of the major problems with conventional wind turbines is that their fast moving blades are prone to damage during high winds and they produce noise, which people living in the vicinity don’t really like. To solve the problems encountered with conventional wind turbines, Mecanoo Architects and Delft University of Technology have joined forces to develop a scale model of a bladeless windmill, which is now viewable in front of the on-campus faculty building dedicated to engineering, mathematics and computer science.

World’s lightest material to help clean oil spills

Graphene Aerogel_1

While there is no dearth of materials that can claim to be among the world’s heaviest, the world’s lightest title was being held by aerogel for more than eighty years. The material, which is also called “frozen smoke”, is 96 percent air and hence its weight is less. Last year researchers developed aerographite, which quickly jumped into the number one spot and one cubic centimeter of the stuff weighs just 0.2 milligram.

Bio-batteries to become a reality with energy generating bacteria

energy producing bacteria

Scientists over the world have for long tinkered with the idea of generating clean electricity with the help of bacteria, which the world knows can transfer electricity into metals and minerals. Taking forward the research, a team of scientists at the University of East Anglia has found that marine bacteria called Shewanella Oneidensis, have proteins that can produce an electric current by simply touching the mineral surface.

Researchers develop low-cost catalyst to produce hydrogen from water

affordable catalyst for producing hydrogen from water

While producing hydrogen by simply using solar energy and water seem to be the holy grail of clean energy, actually the process isn’t as simple as the one you might have tried out in your chemistry lab. Producing large quantities of hydrogen, while making use of minimum amount of electricity uses catalysts, which are usually, made using expensive and rare-earth metals, driving up the cost of hydrogen hence produced. As a solution, two chemistry professors from the University of Calgary have created a new method of water-splitting catalysts using abundant metals.

Recyclable solar cells made using natural substances from plants and trees

Recyclable solar cells

Solar cells may let you harness sustainable energy, but they also create electronic waste once their life cycle is over. Addressing the issue, researchers at Georgia Institute of Technology and Purdue University have come up with sustainable solar cells that are made using natural substances from plants and trees, which can be recycled to reduce the electronic waste that is piling up all across the world.

Polar Rover – World’s first wind powered, satellite controlled, autonomous rover for Antarctica

Polar Rover

Mars rover, Curiosity, might have got all the praise and attention in the recent past, but that surely doesn’t mean there is nothing so impressive about the robot rovers on earth. Here comes one from the China’s Kunlun Polar Research Team in Antarctica, the Polar Rover and it is to impress you for sure. Made to explore the frozen surfaces of the Antarctica, Polar rover is a research vehicle powered solely by renewable energy.

AA ewind is a four-wheeled electric car with a difference

AA ewind concept electric car_1

With the ever increasing cost of fossil fuels and the concerns about air pollution looming large, auto makers and designers have taken up the challenge to come with affordable, and above all, compact electric vehicles that are easy to ride and easy to park. Working on the same lines and recognizing what tourists want on their next vacation, designers Alex Casabo and Cesar Z have come up with the AA ewind.
