The Robotboat will tell you stories about the oceans’ health

The Robotboat Mark VI is an autonomous sailing robot which study the oceans. It needs no fuel, it sails itself, with the help of wind and its sensors are solar powered. It can be considered as a satellite for the seas. According the engineering team developing the robot , it would be capable of ambitious missions like trans-Atlantic crossing, measure oil leaks, the Pacific garbage patch, boundary currents, marina life, coral reefs and icebergs.

Good Examples: Oslo needs to import garbage to generate its energy!

We are used to hear about abundance of garbage and dealing with this as a problem. Well, Oslo could solve it by importing other’s garbage and generate heat and energy for almost half of the city and most of its schools by burning it. And believe it or not, the city has literally run out of garbage to burn. And it’s not just Oslo that needs garbage, The New York Times reports. Across Northern Europe burning garbage to generate heat and energy is a quite common practice in recent decades and the demand for trash already has exceeded the supply. This kind of waste management in Oslo plays a role in the achievement of a reduction of its CO₂ emissions by 50% by 2030.

Harvesting electricity directly from plants?

Plants are the best converters of solar energy and in the searching for alternatives of conventional power sources the scientists are coming closer and closer to nature. Researchers for the University of Georgia are developing a new technology that allows using plants to generate electricity. Plants use sunlight to split water molecules into hydrogen and oxygen and electrons, which help in producing sugars (energy), are freed. ”We have developed a way to interrupt photosynthesis so that we can capture the electrons before the plant uses them to make these sugars,” said Ramaraja Ramasamy, assistant professor in the UGA College of Engineering and the corresponding author of a paper describing the process in the Journal of Energy and Environmental Science.

“Biomass” will monitor the Earth’s biomass

“Biomass” is a satellite which will be launched in 2020 and will calculate the amount of carbon stored in the world’s forests. Over a five-year mission it will monitor for any changes in the forests and should help researchers understand better the role trees play in the Earth carbon cycle and the influence this has on the planet’s climate, BBC reports. The “Biomass” mission was approved by the European Space Agency and the satellite will be the seventh of the agency’s Earth Explorers – a series of spacecraft designed to do innovative science in obtaining data on issues of pressing environmental concern.

Climate change will force people to leave their homes!

“Climate change ‘will make hundreds of millions homeless’”, the Guardian alarms. According to Lord Stern, an economist and climate change expert, it is very likely that millions of people will have to leave their homelands in the near future as a result of global warming. Despite all the warnings of scientists about raising levels of CO₂ concentrations, the output is still increasing and consequences have already become more or less clear and unfortunately considered as severe. The recently announced 400 ppm concentration of carbon dioxide is considered as a point where the world will inevitably experience a catastrophic rise in temperatures. The article is warning that agriculture could fail on entire continents leading to migration of people and conflicts over land.
