Threat to the climate? – Our brains!

Threat to the climate? - Our brains!

We install LED lights in our house and then we step with a clear conscience in the aircraft for a holiday in Thailand.

Our brains and hearts are the biggest obstacles towards more sustainability. Technology is not the issue.

That concludes Scientias in an interview with the Norwegian psychologist Per Espen Stoknes. Read More

Nocera bacteria absorb CO2

Professor Daniel G. Nocera (Harvard) has succeeded in changing bacteria genetically so that they can absorb CO2 and convert it into alcohol.

This news has been reported by the American magazine Forbes. But, according to Nocera:

this bacteria does not solve the CO2 problems.

Gravitational waves detected

Albert Einstein's gravitational waves proven by LIGO

“This is truly a scientific moonshot and we did it. We landed on the moon,” said David Reitze, LIGO’s executive director.

Gravitational waves detected: Einstein would be thrilled! David Reitze and his team did it!

On September 14, 2015, scientists from the LIGO Scientific Collaboration and the Virgo Collaboration observed the collision and fusion of the two black holes by directly measuring the gravitational waves emitted during the collision using the LIGO detectors. Read More

different technologies can be used for micro-CHP, including stirling engines, rankine engines, internal combustion engines, and fuel cells.

Fuel cell based micro CHP units in homes and commercial buildings can help the electricity grid assimilate more renewables according to the Technical University of Denmark.

Scientists published a report explaining the need to create a market for electricity services to draw new technologies such as micro CHP into wider use and accelerate the cost reduction needed for general consumer uptake. Read More

Antarctica: Glaciers are melting dangerously fast

Satellite images taken between 2002 and 2010 showed that glaciers remained about the same size. But since 2009 it is different.

Glaciers in parts of the Antarctic that was thought to remain stable since 2009, have been melting dangerously fast. A group of researchers wrote this in the journal Science, published yesterday.

According to the scientists, the water level is increasing to dangerous levels for the coasts from New York to Shanghai.

Roadmap with proven integrated and sustainable water resource approach

water use cycle st

Sustainable water management cycle

Water is world wide a fundamental resource challenge.

Also for California – with its very fast growing cities as Los Angeles and San Francisco. Water planning and management is a critical underpinning of California’s economy and environment.

This roadmap ensures an integrated and sustainable water resource approach.

Recycled CO2 produces sustainable energy

Ring Receiver Reactor Recuperator produces synthetic fuels

Ring Receiver Reactor Recuperator produces synthetic fuels

Researchers at Sandia National Laboratories have developed a prototype machine that utilizes the sun’s energy to convert water and carbon dioxide into the molecular building blocks that can be utilized as transportation fuels. If researchers can make this device produce twice the energy generated by the natural process of photosynthesis, it will do great service to environment. It will pave the way to recycle CO2.
