As scientists look for more ways of powering our future without reliance on fossil fuels, one potential avenue for generating energy is the development of foldable and wearable power sources. The idea is that these could be incorporated into clothes and other fabrics, providing a source of energy on the move.
This is a pretty big challenge, but one that doesn’t faze a team of researchers from the Georgia Institute of Technology, who have been busy creating a fabric which can harness energy from both sunshine and motion.
The Supreme Court and Congress have shown us that laws in our society are far from permanent—if enough people want it, the law can be changed. In the realm of science, though, laws are paramount. A newly demonstrated concept is not considered true until it has been confirmed by many other studies—even then it is only considered a theory, or a rule. Only the most absolute, time-tested concepts become laws and are generally accepted as unchangeable facts of nature.
As it becomes more and more apparent that our days of relying on fossil fuels are numbered, scientists are investigating alternative ways of producing fuel to power the future. And the biological processes used by plants to create energy might just hold the answer.
Our insatiable need for energy is frequently met through the use of fossil fuels. The impact of this reliance on our climate is now becoming clear, as is the need for a realistic alternative to power our future.
Implantable microelectromechanical systems (iMEMS) have a number of exciting applications for medicine in the future, including the delivery of drugs to treat certain localized cancers.
A new camera called Mosaic-3 is in place at the Kitt Peak National Observatory in Arizona, and is now halfway through completing a two-year mission to record images of far-off galaxies and stars. The upgraded camera now includes light sensors developed at the U.S Department of Energy’s Lawrence Berkeley National Laboratory, making it one of the best tools we have to study outer space.
Some countries lead the way when it comes to renewable energy, and Iceland is definitely one of them. The country already runs on 100% renewable energy, with the majority coming from geothermal sources and hydroelectric dams. Researchers there are also working on new ways to harness energy from the strong Icelandic winds that are a feature of the island.
In the classic science fiction novel, 20,000 Leagues Under The Sea, Captain Nemo said, “…sodium batteries have been found to generate the greater energy, and their electro-motor strength is twice that of zinc batteries.”
Boy, was he right! (Of course, Nemo was referring to ordinary batteries versus potential reversible, rechargeable ones)
The National Science Foundation (NSF) is one the US government agencies that was created to “promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense.” They do this by funding basic research in science and engineering to the tune of $7.5 billion dollars a year (FY 2016), which is less than 0.05% of the total federal budget.
Class Insecta consists of the largest number of species in the world with over 1 million documented types, and they seem to have roused humans and their research owing to the insects’ extraordinary competence while maintaining body weight-balance and mid-flight control due to their natural anatomy. The wings flutter at a high frequency, approximately 120 times/min, allowing them to easily fly with a great momentum and dodge obstacles in their path, simultaneously. Besides this, with their miniature yet strong build achieve a multitude.
The need for reliable energy production worldwide is growing at a rapid rate, with it being estimated that by 2050, our global energy needs will have doubled. This comes at a time when our reliance on fossil fuels is being tested as it becomes more apparent that these are not a sustainable source of energy for the future.
As the world supply of fossil fuels continues to dwindle, and the threat from global warming grows more dire, it’s becoming ever more critical to develop new forms of energy that are both renewable and kinder to the environment. Solar energy seems like one of the most promising new technologies—the sun shines everywhere, and gives our planet all the energy it has needed to thrive for billions of years, so why not harvest it?

Humans consume large amounts of energy for transporting goods, running our industries, bringing comfort to our homes, and powering our cities. In the United States, a majority of the energy consumed comes from petroleum, natural gas, and coal. 91% of the coal goes towards generating electric power; however, it also increases production of greenhouse gasses.
In the future, energy from our bodies will be stored in small-size portable battery, by something known as “Triboelectric generators”, which are basically power converters. They generate small amounts of electrical power from mechanical movements, like rotation, sliding, vibration, walking, or finger tapping.
