How do we reduce the distrust in the face of climate change and other existential threats? Teaching scientific reasoning skills is proposed.
Quantum tech is going green.
A new take on highly sensitive magnetic field sensors ditches the power-hungry lasers that previous devices have relied on to make their measurements and replaces them with sunlight. Lasers can gobble 100 watts or so of power — like keeping a bright lightbulb burning. The innovation potentially untethers quantum sensors from that energy need. The result is an environmentally friendly prototype on the forefront of technology, researchers report in an upcoming issue of Physical Review X Energy.
The big twist is in how the device uses sunlight. It doesn’t use solar cells to convert light into electricity. Instead, the sunlight does the job of the laser’s light, says Jiangfeng Du, a physicist at the University of Science and Technology of China in Hefei.
Electric vehicles have often been hailed as the future. Major motoring companies are aiming to produce nothing but electric vehicles in the future, and some aspire to hit that target by the end of the decade. Cars that are traditionally seen as so-called gas guzzlers — like pickup trucks, muscle cars, and hummers — all have electric equivalents. Governments, including the one running the United States, are improving infrastructure, offering tax incentives, and enacting policies aimed at getting more electric vehicles on the road. And modern-day industrial icons like Elon Musk, who obviously has a vested interest in the electric car’s success, constantly promote the concept. Musk recently published a tweet that likened internal combustion engines to the steam engine — an archaic method of producing mechanical power.
The rapid development of geothermal energy can contribute not only to reducing greenhouse gas emissions but also to the production of environmentally sustainable lithium for EV batteries.
Jane Marsh describes how a Salton Sea project is producing both geothermal energy and lithium salts suitable for EV batteries.
The loss of life would be equivalent to six planes, each carrying 200 passengers, killing everyone on board, every year.
Reducing air pollution from road transport will save thousands of lives and improve the health.
In our published research we evaluated the costs and benefits of a rapid transition. In one scenario, Australia matches the pace of transition of world leaders such as Norway. The modeling estimates this would save around 24,000 lives by 2042. Over time, the resulting greenhouse emission reductions would almost equal Australia’s current total annual emissions from all sources.
We’ve partnered with UTS to develop Smart Bin Technology, which automatically separates glass, metal and plastic bottles for recycling.
The U.S.-based facility hopes to capture CO2, roughly the equivalent of 5 million return flights between London and New York annually.
A U.S. climate tech company has developed a project that could remove millions of tonnes of carbon dioxide from the atmosphere annually.
CarbonCapture Inc. has revealed plans for the largest carbon capture facility in the world in Wyoming, in an exclusive partnership with premier carbon storage company Frontier Carbon Solutions, according to a press release published by Business Wire last week.
The steel structures will be fabricated at Westcon’s shipyard in Florø and then transported to Dommersnes Industrial Area for complete assembly and testing. The complete turbine is then towed to Bokn, where it will be installed.
SeaTwirl has been around for a while now. In July 2015, the company first deployed its prototype named S1 off the coast of Lysekil in Sweden. The S1 is a small, 30-kW test version of its floating turbine technology. Rising 13 meters above the waterline and reaching down 18 meters below, it offers energy-producing companies an attractive test platform for offshore wind power and an alternative to diesel generators in remote areas that are off-grid or prone to power outages. It’s been connected to the grid and tested according to plan since its deployment. S1 has withstood harsh weather conditions, autumn and winter storms reaching hurricane wind speeds.

Industrial heat consumes a huge proportion of global energy. Rondo Energy says its brick-toasting heat storage device is so cheap and efficient that it makes decarbonization an instant no-brainer across a huge range of industries. Bill Gates agrees.
According to 130,000 years’ worth of data on what mammals have been eating, we’re in the midst of a mass biodiversity crisis. Not great!
This revelation was borne of a new study, conducted by an international team of researchers and published in the journal Science, that used machine learning to paint a detailed past — and harrowing future — of what happens to food webs when land mammals go extinct. Spoiler alert: it’s pretty grim stuff.
“While about 6 percent of land mammals have gone extinct in that time, we estimate that more than 50 percent of mammal food web links have disappeared,” Evan Fricke, ecologist and lead author of the study, said in a press release. “And the mammals most likely to decline, both in the past and now, are key for mammal food web complexity.”
