Tin, silicon and a few other elements have long been languishing on chemists' list of electrode materials that could help lithium-ion batteries hold more energy. A new way of structuring these materials could at last allow them to be used in this way
A method for getting oil out of tarry sands could reduce the costs and lower the greenhouse-gas emissions associated with its extraction.
The Nissan Leaf can run 70-plus miles on a single charge. Now, it can also power a family home for two days if it needs to.
The "month-by-month" chart shows a definite economic downturn starting full bore in the April/May time period. Usage is now falling and is well below 2010 levels and approaching 2009.
In Russia’s far east, temperatures can fall to 35 degrees below zero. Many islanders herd reindeer. In January, oil crews drilled the world’s longest and deepest extended-reach well, 7.7 miles down into the ground and 7.1 miles out under the ocean.
Nanotechnology promises to enable tiny, intricate circuits powering devices on any surface. But unless they’re harvesting energy from something like a heartbeat, the devices can only be as small as the smallest battery.
Despite improvements in the design of wind turbines that have increased their efficiency, wind farms are rather inefficient, Dabiri notes. Modern farms generally employ horizontal-axis wind turbines (HAWTs)-the standard propeller-like monoliths that
In work that could improve solar cells and LEDs, researchers have, for the first time, made practical working devices out of three-dimensional photonic crystals.
Too much gadget and not enough battery. A problem any early adopter of a smartphone has faced (and, to some degree, is still facing) and can be a particular hassle when you’re traveling. Lots of gadgets means lots of charging cords or spare batteries
The Elektra One from PC-Aero is making its North American debut here at Airventure. The sleek electric single-seater is a prototype of the airplane designer Calin Gologan hopes will go into production next year.
While all other major electronics components--things like transistors, displays, and other circuitry--have been made transparent, no one had taken the time and effort to create a transparent power source.
Seventy percent of the Japanese public supports centre-left Prime Minister Naoto Kan's policy to make the country nuclear free in future but most people still want him to quit
At $10,000 a piece, electric-car batteries are too expensive to throw out or recycle into scrap materials.
American Electric Power's recent decision to scrap plans to capture and sequester carbon dioxide at a West Virginia power station is just the latest in a string of cancellations of carbon capture and storage (CCS) projects.
It turns out nearly half of the Earth’s total heat output comes form decaying radioactive elements like thorium and uranium in the Earth’s crust. But that’s an answer that begets more questions.
AAA is rolling out North America’s first fleet of quick-charge trucks that will rescue dead electric vehicles and get them back on the road.
The humble street light is joining the ranks of wind turbines and solar power plants in supplying renewable energy to the electricity grid.
The ocean is a big place. And if you're going to steal a bunch of electricity from it, you'll need a big generator.
he automakers Volvo and Jaguar are testing the possibility of using flywheels instead of batteries in hybrid electric vehicles to aid acceleration and help engines operate more efficiently.
Chinese startup develops new, low-cost ways to improve the properties of lithium-iron phosphate, a leading electrode material.
A new ultra-wideband antenna printed on paper or plastic can harvest ambient energy, enabling wireless sensors to tap into electromagnetic currents in the air around them.
The Swedish automaker’s already wowed us with the C30 Electric, a car that it really ought to go ahead and sell already. Volvo keeps telling us we’ll see the C30 electric (pictured) in 2013. Then it wheeled out the diesel-electric V60 Plug-In Hybrid.
Heat exchanger technology--the cooling machinery that ferries internal heat away from your PC, your computer, your air conditioner, and other appliances--hasn’t changed too terribly much for decades.
Engineers at MIT are tinkering with all sorts of advanced solar power technology, like self-assembling solar cells, virus-structured cells and an artificial leaf system that mimics photosynthesis. Their latest project can be printed on a regular shee
Oil won't run the world forever, but it will for the next few decades--so how do we get from here to the next energy economy?
California is unique by not just calling for utilities to lay out their grand smart grid plans but also asking them to quantify and measure progress. As advanced as California is with its smart grid ambitions, the initial reported metrics show that t
In these highlights from the hourlong session, Gates argues that nuclear power is still safer than all other energy options, rich countries aren’t spending enough on R&D, and installing solar panels on your roof is not helping to reduce CO2 emissions
It is difficult to believe that this will be the last space shuttle launch. Clearly, I must do something to commemorate this event. But what? How about I look at space ships in orbit and consider the energy required. WITH GRAPHS.
A startup says its compressed-air technology could do a better job of storing the power generated by wind turbines.
For the first time, a jumbo jet used a blend of biofuel and kerosene on a transatlantic flight. Also KLM Royal Dutch Airlines announced a biofuel supply agreement to commence regular flights on a biofuel-petroleum blend on 200 Amsterdam-to-Paris runs
