Solar Cells to Power Pacemakers - Image of Pacemaker

Research team has developed a system of solar cells designed to provide energy to medical implants When many people think of “solar energy,” they often envision solar panels installed on rooftops or large solar farms. Rarely, however, do people think that solar power can be used for more than just providing electricity to a home or business. A team of researchers from the Bern University Hospital and the University of Bern are working to change this. The team has developed a new solar device that can be used to power…

Scientists develop new technology to efficiently store solar energy as hydrogen fuel

Stanford scientist have made major progress in solving solar power’s storage problem Scientists from Stanford University have reached a new milestone in producing and storing the electricity generated by solar energy systems. Solar power has vast potential, having proven in the past that this form of clean energy can provide abundant electricity when it is needed. The problem, however, is that storing this electricity has proven to be quite difficult, which has made solar energy less attractive when compared to other forms of power. The scientists from Stanford believe that…

Light therapy products become increasingly environmentally friendly

A company called LTO has broken away from the traditional disposables to provide an eco-friendlier option. Light Therapy Options (LTO), a Connecticut-based company providing products meant for healing and treating a range of different skin conditions, is beginning to stand out and above its rivals in this increasingly competitive industry by selling products that are environmentally friendly on several different levels.  These high powered (HP) LED lights are designed to expose affected skin to certain specific wavelengths. While there have been several light therapy products that have made their way…

Scientists identify plant enzyme that could lead to mass-production of biofuels

Researchers may have found an enzyme that could enable any plant to product fuel. In their quest to find the next best environmentally friendly fuel, a team of international researchers have announced that they have successfully isolated an enzyme with lycopaoctaene synthase activity in common algae known as Botryococcus braunii. This enzyme is responsible for hydrocarbon oil production and the scientists are investigating how to use the enzyme to mass-produce biofuels. This discovery could be a breakthrough for the alternative fuel industry. Although not as clean as other forms of…

U.S. scientists may have found new technique to lower biofuel cost

Decreasing plant lignin could help make green fuel cheaper. Biofuel could become cheaper as scientists have shown for the first time that it is possible to lower lignin in plants by tweaking an enzyme; a discovery which could be highly beneficial to the bioenergy industry. The technique discovered by the scientists from the United States Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), could help reduce the cost required to convert biomass into carbon-neutral fuels used to power cars and other sustainably develop bio-products, reported Phys.org. The technique lowers…

Scientists Find Cheaper and Eco-Friendlier Way to Make Biofuels

Researchers have discovered a low-cost method to deliver carbon dioxide (CO2) to microalgae. Although the growth of microalgae can be sped up by carbon dioxide, the CO2 has to be free of contamination or the algae die. Researchers from the Melbourne School of Engineering have found a cheap way to purify the carbon dioxide within the power station flue gasses by absorbing the CO2 into a liquid, allowing it to be delivered to microalgae, which makes it possible to harvest the microalgae and make biofuels. This purification process is typically…

CO2 emissions have “postponed” next ice age by tens of thousands of years

Human-generated greenhouse gases emissions may delay the Earth’s next ice age by a minimum of 100,000 years. Carbon (CO2) emissions created by humans have been blamed for having many unpleasant effects on the planet, from severe droughts, to extreme weather, to pollution, to rising sea levels. However, a team of German scientists say that these CO2 emissions are likely the reason why there are no signs of a new ice age and why there won’t be one in the near future. The Industrial Revolution saved the planet from the onset…

Light recycling technology prevents incandescent bulbs from wasting energy

Researchers may have found a way to make traditional light bulbs more energy efficient. Scientists at MIT and Purdue University have created a new recycling technology involving incandescent lights that enables this type of light to be more energy efficient. These warm glowing conventional light bulbs, which were first commercialized by Thomas Edison, have fallen out of favor over the past several years because they are far less efficient than compact fluorescents and LEDs. However, researchers have created a super-efficient two-stage incandescent bulb that reuses the heat it emits, allowing…

New research may have found a way to develop better biofuel

Researchers have created a new “nano-reactor” that could catalyze hydrogen production. According to a new study published in the scientific journal, Nature Chemistry, researchers have managed to develop a new biomaterial, by hiding a modified enzyme inside a virus, which is capable of efficiently catalyzing the production of hydrogen. Dubbed the “nano-reactor,” the modified enzyme may result in a biofuel production process that is more efficient and profitable. The modified hydrogen-producing enzyme is 150 times more efficient than an enzyme that has been unaltered. Within the capsid, which is the…

Biofuel may be produced from roadside weed

Researchers from Nevada think they may be able to produce diesel fuel from gumweed. Nevada scientists believe that curlycup gumweed, a common roadside weed that grows across much of Nevada’s high desert, may be ideal for producing biofuel. More specifically, the researchers think that they are close to producing diesel fuel and may even one day be able to produce jet fuel from the plant, reported the Associated Press. Very little water is needed to grow gumweed. Back in the 1980’s, a University of Nevada researcher and mining engineer, Darrell…

New research reveals fracking may affect male fertility

Exposure to chemicals used in hydraulic fracturing has been connected to reduced sperm count in adult male mice. Hydrualic fracturing, the controversial oil and natural gas drilling technique, more commonly referred to as fracking, has been linked to several negative effects including earthquakes, water contamination, health problems and, most recently, premature births. Now, new research conducted on mice has shown that chemicals used in the fracking process can damage the reproductive health of male mice, by potentially causing lowering sperm count, larger testicles, and higher levels of testosterone. The researchers…
