New Clean Energy Source
By intensely focusing the sun's rays on a rare earth oxide, researchers have discovered a reactor that could produce fuel from water in an easily stored form.
The reactor hits ceric oxide with an intense blast of focused sun, which heats up the material enough that it starts to shed the oxygen from its lattice. The material then merrily strips the oxygen from either water or carbon dioxide if they're nearby, leaving hydrogen or carbon monoxide—which can be combined to form hydrocarbon fuels using further catalysts. Still in its early stages, the reactor demonstrates a sun-to-fuel efficiency of 0.7%-0.8%, but according to researchers these are "largely limited by the system scale and design rather than by chemistry."
New research offers a tip for politicians who don’t want to be seen as corrupt: don’t get a big head.
These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.
We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
