Getting to the heart of carbon nanotube clusters

Integrating nanoscale fibers such as carbon nanotubes (CNTs) into commercial applications, from coatings for aircraft wings to heat sinks for mobile computing, requires them to be produced in large scale and at low cost. Chemical vapor deposition (CVD) is a promising approach to manufacture CNTs in the needed scales, but it produces CNTs that are too sparse and compliant for most applications. Applying and evaporating a few drops of a liquid such as acetone to the CNTs is an easy, cost-effective method to more tightly …

Back-and-forth exchanges boost children’s brain response to language

A landmark 1995 study found that children from higher-income families hear about 30 million more words during their first three years of life than children from lower-income families. This “30-million-word gap” correlates with significant differences in tests of vocabulary, language development, and reading comprehension. MIT cognitive scientists have now found that conversation between an adult and a child appears to change the child's brain, and that this back-and-forth conversation is actually more critical to …

Neural networks everywhere

Most recent advances in artificial-intelligence systems such as speech- or face-recognition programs have come courtesy of neural networks, densely interconnected meshes of simple information processors that learn to perform tasks by analyzing huge sets of training data. But neural nets are large, and their computations are energy intensive, so they're not very practical for handheld devices. Most smartphone apps that rely on neural nets simply upload data to internet servers, which process it and send the results …

Water-Based Air Conditioning Slashes Energy Usage & Uses No Refrigerants

Researchers in Singapore have invented a new air conditioning system that uses no compressor or chemical refrigerants. It is 40% more energy efficient than conventional air conditioners and creates drinking water in the process. Can you say "game changer," boys and girls?

Beyond SolarCity, Vivint Solar and Sunrun: Who Is Actually Growing in the Residential Solar Market?

A chill has hit home solar. According to GTM Research's latest U.S. Solar Market Insight Report, Q3 2017 was the third consecutive quarter that the residential solar market fell by installation volume. It's easy to blame the “Big Three” for this downturn -- collectively, SolarCity, Vivint Solar and Sunrun are down 32 percent in installation volume over the first three quarters of 2016, according to the latest U.S. PV Leaderboard. At the same time, we talk about the rest of the market --

The Best News Yet for Energy Storage in New York

Once New York Governor Andrew Cuomo endorsed energy storage as a component of his clean energy strategy, he went in big. Cuomo kicked off 2018 with a series of clean energy proposals, including a groundbreaking energy storage pledge: to deploy 1,500 megawatts by 2025 as the state works toward 50 percent renewable energy by 2030. The target came just a month …

U.S. regulator rejects coal, nuclear bailout, says renewable energy may double by 2020

For much of last year, U.S. Energy Secretary Rick Perry pursued a plan that, in essence, would prop up the financially challenged U.S. coal and nuclear industries. His proposal, submitted to the Federal Energy Regulatory Commission last fall, provided financial subsidies to electric-generation plants that kept 90 days of fuel onsite. Natural-gas...

Iran and Oil Prices in 2018

The turn of the year brought the usual year-end analyses of energy events, along with predictions and issues to watch in the year to come. I tend to focus on tallies of risks and large uncertainties. There's no shortage of those this year, and the current unrest in Iran moves the risks associated with that country higher […] The post Iran and Oil Prices in 2018 appeared first on The Energy Collective.

Winds of Change: Britain Now Generates Twice as Much Electricity from Wind as Coal

Just six years ago, more than 40% of Britain's electricity was generated by burning coal. Today, that figure is just 7%. Yet if the story of 2016 was the dramatic demise of coal and its replacement by natural gas, then 2017 was most definitely about the growth of wind power, write Grant Wilson and Iain Staffell.

Norway Reaches Carbon Emissions Goal From Transportation Three Years Early, Thanks To Tesla

In 2012, Norway set a goal for transportation-related emissions. It decided that 85 grams of carbon dioxide per kilometer would be the official target for the year 2020. The latest figures as reported by Norwegian news channel NA 24 show that goal was achieved and even exceeded in 2017, 3 years ahead of schedule.

No, electric cars (still) aren’t crashing the grid. Again.

Remember all those brownouts we experienced last week because everyone plugged in their electric cars? No? Oh right, that didn't happen. It still isn't happening. And it's unlikely to ever happen. That's the conclusion of a study by the Natural Resources Defense Council (NRDC), using infrastructure investment data from California's biggest...
