Rooftop solar panels could potentially produce enough energy for worldwide consumers. (Image Credit: Vivinti Solar / Unsplash)   Today’s rooftop solar panels are 79% cheaper compared to the ones in 2010. This led to home and business owners installing solar photovoltaics, allowing them to reduce their carbon footprint. At the same time, they rely less on electrical grids. One question remains, is it possible to develop sufficient rooftop solar panels to generate affordable, low-carbo ...
The new solid-state battery features a cathode composite layer, a sulfide solid electrolyte layer, and a carbon-free micro-silicon layer, making it energy-dense and suitable for electric vehicles and grid storage. (Image credit: UC San Diego via YouTube)   Researchers from UC San Diego have developed a new solid-state battery that promises increased safety, longer life, and energy density. The battery combines two types of technologies, including a solid-state electrolyte and a silicon ano ...
The large high-temperature superconducting electromagnet achieved a field strength of 20 tesla, making it the strongest magnate of its kind ever created on the planet. (Image credit: MIT)   Engineers from MIT and Commonwealth Fusion Systems have successfully tested the world’s strongest high temperature superconducting (HTS) magnet, technology that could become a key component for commercial fusion energy. The magnet achieved a field strength of 20 tesla, making it the strongest of i ...
(Image Credit: Antonie Julien/Unsplash)   SWG3 recently announced that it plans to install an advanced renewable heating and cooling system, called BODYHEAT, which converts a crowd’s body heat into reusable energy. The collected heat can either be used immediately, keeping the audience cool or stored underground to heat the building at a later time. Plans are already underway to install this system by November 1st.   First installed in Scotland, BODYHEAT utilizes heat pumps an ...
The energy-harvesting flooring uses wood with a combination of a silicone coating and nanocrystals, which produces enough energy to power LED bulbs and small electronics. (Image credit: ETH Zurich)   Scientists from ETH Zurich’s Wood Materials Science Center have developed wood-based flooring capable of generating enough energy to power LED bulbs and small electronics. The flooring uses wooden panels with a combination of a silicone coating and nanocrystals to produce a nanogenerator. ...
The Wind Catching System is equipped with small turbines, stands more than 1,000 feet tall, and is situated on a floating platform anchored to the ocean floor. (Image credit: Wind Catching Systems)   Norway-based Wind Catching Systems (WCS) are developing an offshore wind system that will reportedly produce enough renewable energy to power 80,000 homes. A single unit is outfitted with more than 100 tiny turbines, rises around 1,000 feet tall and will see a 50-year service cycle. WCS states ...
(Image credit: Flickr)   It's estimated there are about 8-million tons of plastic littering the world's oceans, and that number continues to grow. While some plastics remain floating once they enter the water, others get thrashed around and break into tiny pieces known as microplastics, which are smaller than 5mm and can sink to the bottom and wreak havoc on oceanic ecosystems. Some of those microplastics come from hand soap, which could cause hermit crabs to become extinct if nothing is d ...
The new battery uses a cobalt-poor, nickel-rich layered cathode (NCM88) and a commercially available dual anion ionic liquid electrolyte, which provides a higher energy density of 560-Wh/kg and increased stability. (Image credit: Karlsruhe Institute of Technology)   Lithium-ion batteries are part of our daily lives, and we use them to power our mobile devices and electric vehicles. In the past, lithium-metal batteries have had a tendency to become stable or even explode under some circumst ...
This image shows the internal structure of INF’s preamplifier support. (Image Credit: Damien Jemison/LLNL)   Scientists at the Lawrence Livermore National Laboratory in Northern California used a unique nuclear fusion creation technique at the National Ignition Facility to yield over 10 quadrillion watts of power, a world record. The team achieved this feat by focusing intense light beams from 192 giant lasers at a tiny pea-sized hydrogen pellet, releasing 1.3 megajoules of energy in ...
A research team in Germany developed the world's smallest micro supercapacitor, which can be safely used in the human body. (Image Credit: Research Group Prof. Dr. Oliver G. Schmidt)   Scientists in Germany recently created the world's smallest micro supercapacitor, achieved by combining tiny electronics with origami-inspired fabrication. The micro supercapacitor, which is smaller than a speck of dust, stores the same voltage level as an AAA battery. It also utilizes crucial blood ingredie ...
The 3D printed channel fasteners were installed during a planned fuel outage at the Browns Ferry Nuclear Plant Unit 2 in Athens, Alabama. (Image Credit: Framatome)   This prompts a serious thought – would you trust a 3D printed part in a mission-critical application? Have you ever used a 3D printed part in a product design?   During a planned refueling outage, Tennessee Valley Authority (TVA) installed four 3D-printed fuel assembly brackets, now in routine operation, at its Bro ...
The breakthrough could pave the way toward faster electronics. (Image Credit: Intralist.com/Unsplash)   Northeastern University scientists claim to have made a breakthrough quantum physics discovery that could help lead to the next generation of computers, sensors, and switches.  Their findings are based on the discovery of a topological axion insulator, a unique quantum matter state that was once thought to be theoretical but now exists.   The axion insulating state was achiev ...
The team’s purified tin selenide in polycrystalline form could lead to affordable devices that convert heat waste into electricity. (Image Credit: Northwestern University)   Scientists from Northwestern University and Seoul National University recently found a way to convert heat into electricity through a purified tin selenide in polycrystalline form, an inexpensive solution. The thermoelectric material outperforms the single-crystal form, making it the most efficient system to date ...
Cambridge University researchers developed a new technique that could fully charge most smartphones and laptops in as little as five minutes. (Image Credit: Pixabay)   Researchers at the University of Cambridge developed a low-cost lab-based technique that could fully charge most laptops and smartphones in just five minutes. The key advancement may lead to better battery materials and progress toward next-gen battery development, allowing a greater shift to a fossil-fuel-free world.   ...
Using Yazami’s new technique could charge an EV battery in just ten minutes. (Image Credit: Waldemar Brandt/Unsplash)   Dr. Rachid Yazami believes his invention, a graphite anode that allows lithium-ion batteries to achieve high performance, could quickly charge an EV battery with a newfound technique. It all started in the mid-1970s when scientists realized that graphene could allow molten or powered lithium to serve as an energy storage material. However, they couldn’t make i ...
