The Green Optimistic

Scientists from the University of Sheffield, UK have demonstrated that some bacteria named Nostoc could be used to power our future hydrogen cars. Their research was published in the journal Bioinformatics, and it could have powerful green consequences for the environment.

A team of scientists from the Monash University, Australia, has designed a fuel cell which will be used in the latest generation of hybrid cars. Their fuel cells could make the vehicles more reliable and more cheap to build.

MIT researchers found out a way to create energy by mimicking the photosynthesis process that green plants acquire their energy from. Prof. Daniel G. Nocera and former MIT graduate student Alan F. Heyduk invented a hydrogen-producing compound. They also use a catalyst and small amounts of light.

Michael Strizki’s house is the most low impact house I’ve ever seen. He lives his life off-grid, because his home system feature solar panels, 10 hydrogen tanks filled with the excess energy from the solar panels, with the hydrogen taken out of water, and a 15 year-old geothermal system, that covered its price 8 times since it was installed.

This video is a clip from a 1978 CBC News, showing Jack Nicholson driving a hydrogen powered car. The concept existed since then, the hydrogen was packed in high pressure tanks, and the engine’s timing (top dead center) was retarded a bit (probably 8 degrees, it’s a common value). And, as extra value, the hydrogen was obtained from solar power, through some solar panels, cutting edge tech at that time.

Penn State researchers have found a cheaper method of producing hydrogen from water by the same old effect of electrolysis aided by the Sun’s rays. They do not use classic solar cells, because these are expensive, but made a nanotechnology-based solar cell, called photoelectrochemical diode, that is simplistically said on the bottom of the water holding recipe.

A company, named QuantumSphere, has designed a metal coating system made for electrolyzers, made out of nanoparticles of NiFe (Fero-Nickel, or in plain english, a combination between iron and nickel). This coating would cover the electrolyzers’ anode and cathode and increase the actual contact surface with water by over 1000 times!

As you already know, Earth’s ecosystems are in a closed-loop. Researchers from the University of Birmingham have created a closed loop hydrogen energy eco-system based on two types of bacteria and a twist of fuel cell technology. How did they do that?
