Scientists at the University of Wisconsin-Madison claim to have found clean hydrogen fuel in the unholy mix of zinc oxide crystals, water and noise pollution. Researchers say that the process will not require any catalyst like oil, and will manage to be fairly efficient. Which makes it quite a winner, with noise pollution being quite ubiquitous in our world, using it to generate clean fuel sounds simply great.

Cargo ships are probably the cheapest and most efficient method to transport your cargo – and they also take considerably less energy per ton of cargo than most other methods. Still, the fuel used to power cargo ships is notoriously known as one of the dirtiest fuels in the world, and in fact cargo ships alone are known to contribute at least 3-4% of the world’s greenhouse gas.

A canal boat using fuel cells for power made its first cruise this Wednesday. The “Nemo H2″ has a capacity of 87 passengers, and is the first boat to utilize new fuel cell technology, which combines hydrogen and oxygen to create electrical power and water – while also leaving no harmful traces in the environment, emitting only water vapor.

Nuclear power plants in Germany are on their way to an extended life, surmounting the huge obstacles in their path. There is a vehement opposition to nuclear power plants in Germany, and most of the population believes that the country should let go of nuclear power plants. The new policy aims at keeping the old plants running to ultimately have greener energy take over the existing system, but it may also pave the way for new nuclear plants.

The World Solar Challenge started off in 1987, and features teams of some of the top engineering colleges from around the world vying to get hold of a top spot, while traveling thousands of miles in solar powered racecars. The challenge puts up a grueling task for the vehicles which are powered by only solar energy. This year, the cars covered a distance of nearly 1,864 miles through a route that stretched from Darwin in Northern Australia to Adelaide in South Australia.

A study by researchers at the University of Sao Paulo, Brazil, has found that ethanol can be a viable alternative to gasoline for vehicles, and at the same time, its use can effectively reduce emissions. Brazil is one of the world’s largest producers of sugarcane, and cane-based ethanol. Researchers found that the ethanol provides nearly eight times the energy used to create it, and that number could increase further with the introduction of new technologies and plant varieties.

Electric cars have been hailed as the modern, non-polluting vehicles, but it’s too early to shower them with all the praise, say scientists. In fact, if things don’t change dramatically, electric vehicles may not be very green even in 2030. The problem of course doesn’t lie entirely in the zero-emission electric cars, it has more to do with the generation of electricity for the vehicles.

The bizarre story of a Colorado family’s runaway balloon aircraft this afternoon got me to thinking:

How many helium-filled balloons are required to lift a human off the ground?

Chicago’s bid for the 2016 Summer Olympics is bold. It’s exciting. And, it’s green.

In fact, Chicago 2016 organizers even call their concept of the Olympics the “Blue-Green Games.”

Blue for clean air and water. And, green for parks and nature. Together, the blue and green combine to create the ideal conditions necessary for optimal athletic performance.

What’s more, Chicago 2016 organizers have developed a comprehensive plan that will deliver the most eco-friendly games in modern history.

The oil resources are diminishing fast and we still haven’t found an apt solution to replace gasoline to power the modern day commuters. But how about a vehicle that only needs compressed air to roll?

Green Speed Air Powered Motorcycle by designer Edwin Yi Yuan

Edwin Yi Yuan has succeeded in designing a concept air-fueled bike dubbed the Green Speed Air Powered Motorcycle. It is not an utterly novel concept for we have heard of compressed air powered vehicles before, but this motorcycle has overcome a couple of problems faced by previous concepts — short range and low speed.
