Due to environmental problems, renewable energy is on the demand. However, one of the major challenges with many sources of renewable energy is that storing the energy produces is yet a problem to be solved. A research team in Finland have developed an interesting procedure that could help overcome this problem.
At a conference that was full of researchers with PhD’s in science and mathematics, a problem was presented. After giving a few minutes to think about the task, only around 5% of the researchers answered this problem correctly. See if you can get it right.
All the growth expectations regarding solar power have been surpassed during the past decade. In 2002, the globally installed photovoltaic (PV) capacity was 2 000 MW, and now, in 2015, we are expecting to exceed 200 000 MW. The capacity has more than doubled every two years, and does not show signs of slowing down. So what has really caused this rapid expansion and what does this mean for our future?
When visiting a new city, have you ever had the feeling that it really reminds you of another city that you’ve been to? The culture, the weather and the people may be different, but you still feel that something is the same. If you’ve felt that way, it may be due to the “fingerprints” of the city.
Scientist have found that by looking at the structure of someone’s brain, it is possible to determine whether they are an introvert or an extravert. There are several differences in a brain whether a person prefers to relax alone or through social interactions.
