Earlier this month, the NTSB released its Aircraft Incident Report on a fire aboard a Japan Airlines Boeing 787, concluding that the fire was probably caused by an internal short circuit within a cell of the lithium-ion battery.
Stanford University's Precourt Institute for Energy, Precourt Energy Efficiency Center and TomKat Center for Sustainable Energy have awarded eight seed grants totaling about $1.5 million for promising new research in clean technology and energy efficiency.
The discovery of a new form of ice could lead to an improved understanding of our planet’s geology, potentially helping to unlock new solutions in the production, transportation and storage of energy. Ice XVI, the least dense of all known forms of ice, has a highly symmetric cage-like structure that can trap gaseous molecules to form compounds known as clathrates or gas hydrates.
Scientists are developing a new kind of “smart window” that can block out heat when the outside temperatures rise. The advance could one day help consumers better conserve energy on hot days and reduce electric bills.
Hydrogen could be an important source of clean energy, and the cleanest way to produce hydrogen gas is to split water into hydrogen and oxygen. But the catalyst currently used to facilitate this water-splitting reaction is platinum. And that’s a problem.
Engineers at Lancaster University are working on powering future giant leaps for mankind. They are major partners of a consortium working on a new project to maximize "energy harvesting" on a space craft of the future.
Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent Sandia National Laboratories study.
During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The last panel of the day focused on energy/environmental solutions and the innovation behind four R&D 100-winning technologies and the complexity of bringing such technologies to the market.
Natural gas power plants produce substantial amounts of gases that lead to global warming. Replacing old coal-fired power plants with new natural gas plants could cause climate damage to increase over the next decades, unless their methane leakage rates are very low and the new power plants are very efficient.
Univ. of New South Wales' solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported. The world-beating efficiency was achieved in outdoor tests in Sydney, before being independently confirmed by the National Renewable Energy Laboratory at their outdoor test facility in the U.S.
Pretty soon, powering your tablet could be as simple as wrapping it in cling wrap. A Univ. of Toronto team has invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture.
A groundbreaking research project by the GW4 Alliance aims to clean up water from a Cornish tin mine, using algae to harvest the precious heavy metals and produce biofuel at the same time. GW4 brings together the South West and Wales’ four leading, research-intensive universities: Bath, Bristol, Cardiff and Exeter.
Noise, excessive vibration and relative inefficiency are drawbacks of the piston-based internal combustion engines (ICE) that power today’s lawn and garden equipment, such as leaf blowers and lawn trimmers. But now Massachusetts Institute of Technology startup LiquidPiston has developed a rotary ICE that it says is significantly smaller, lighter and quieter, as well as 20% more fuel-efficient than the ICEs used in small-engine devices.
Hydrocarbon exploration by definition is the search by geologists or geophysicists for hydrocarbon deposits beneath the Earth’s surface, such as oil (petroleum) and natural gas. In such exploration, the oil and gas industry drills holes into the Earth’s surface to extract the petroleum or natural gas. However, such exploration is expensive, not to mention a high-risk operation.
Taking inspiration from nature, researchers have created a versatile model to predict how stalagmite-like structures form in nuclear processing plants, as well as how lime scale builds up in kettles. The main aim of the research, which is published in Computers & Chemical Engineering, is to reduce the number of potentially harmful manual inspections of nuclear waste containers.
A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles. Batteries have two electrodes, called an anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite.
An efficient method to harvest low-grade waste heat as electricity may be possible using reversible ammonia batteries, according to Penn State Univ. engineers. Low-grade waste heat is an artifact of many energy-generating methods. In automobiles, waste heat generated in winter is diverted to run the vehicle heating system, but in the summer, that same waste heat must be dissipated to the environment.
For years, scientists have been pursuing “artificial leaf” technology, a green approach to making hydrogen fuel that copies plants’ ability to convert sunlight into a form of energy they can use. Now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production. They describe their nanowire mesh design in ACS Nano.
Chemists and engineers at Oregon State Univ. have discovered a fascinating new way to take some of the atmospheric carbon dioxide that’s causing the greenhouse effect and use it to make an advanced, high-value material for use in energy storage products. This innovation in nanotechnology won’t soak up enough carbon to solve global warming, but it will provide a low-cost way to make nanoporous graphene for use in supercapacitors.
A new study will help researchers create longer-lasting, higher-capacity lithium rechargeable batteries, which are commonly used in consumer electronics. In a study published in ACS Nano, researchers showed how a coating that makes high-capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes.
Scientists at the National Physical Laboratory have developed a new method for detecting defects in solar cells using a technique called compressed sensing. Solar panels are being rapidly deployed across the world as costs fall and the need for sustainable, low-carbon energy grows. Being able to effectively characterize solar cells is a key factor in quality control during manufacturing and understanding their long-term behavior.
Two years ago, researchers at the Joint BioEnergy Institute engineered E. coli bacteria to convert glucose into significant quantities of methyl ketones, a class of chemical compounds primarily used for fragrances and flavors, but highly promising as clean, green and renewable blending agents for diesel fuel. Now, after further genetic modifications, they have managed to dramatically boost the E.coli’s methyl ketone production 160-fold.
A short circuit likely due to a manufacturing defect in a Boeing 787 airliner battery caused a fire last year that grounded the planes for more than three months, federal accident investigators said Monday. They also faulted the plane's maker and the Federal Aviation Administration for designing and approving a battery design that didn't protect against such a failure.
Stanford Univ. engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space. The heart of the invention is an ultra-thin, multi-layered material that deals with light, both invisible and visible, in a new way.
As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity. However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology epresents a first step toward harnessing that lost energy.
