To Solve Flying Cars' Biggest Problem, Tie Them to Power LinesIn the age of cord cutting, San Francisco-based startup Karman Electric thinks flying cars should be able to connect to power lines for long-haul routes and go solo when they approach their destination.
But Lochbaum points out that history proves such preparation might not be enough.In its 2012 post-Fukushima review, Florida Power & Light told the NRC that flood protections at its St. Lucie plant on South Hutchinson Island were adequate, despite failing to discover six electrical conduits with missing seals in one of the emergency core cooling systems.
In this sense it’s autonomous to a degree, though the researchers remotely pilot it around.To fly forward, DelFly’s motors tilt the two pairs of wings forward, like a helicopter. Taken together, these wing controls produce a range of maneuvers to rival that of the fruit fly.Animation by TU Delft
Federal, state and local officials, who have already spent days trying to warn people in Florence’s path of the potential severity of the storm, issued some of their most strident pleas yet on Wednesday for people to get out of harm’s way.“We know a lot of our coastal residents have ridden out storms before,” said Gov. Roy Cooper of North Carolina during a Wednesday evening news conference.
The hurricane will then gather strength and spread inland as the center of the storm edges toward the coast on Friday afternoon, bringing torrential rainfall of up to 40 inches that will continue through Saturday and Sunday.Here are the latest developments:• The major power supplier for North and South Carolina, Duke Energy, said that the storm could knock out power for up to three million customers across the two states and that it could take several weeks to restore electricity.• The storm was predicted to slow and the eye could stall just offshore, battering the coast with high waves and dropping as much as 20 to 40 inches of rain in flood-prone coastal areas.
HONG KONG — A super typhoon packing winds of up to 150 miles per hour is heading toward the Philippines, picking up speed over the Pacific on a route that also has Taiwan and the heavily populated southeastern coast of China in its sights.Super Typhoon Mangkhut is on track to hit the northern Philippines with its strongest winds on Friday before striking Taiwan and then possibly veering south toward Hong Kong and mainland China.As many as 43 million people could be exposed to cyclone-strength winds, according to the Global Disaster Alert and Coordination System.
Tree-planting, restoring wetlands and using chemicals to take carbon dioxide from the air will all be needed to reduce the UK’s greenhouse gases in line with government plans, scientists have said.
Wilson, 70, a retired farmer from near Biloela in central Queensland, had planned the trip of a lifetime with her husband, Rod. One impulsive evening in mid-2016 they went online and, sight-unseen, bought a Tesla S75 electric car for the journey.
A growing number of Australians are concerned about the impact of climate change, and more than half of a survey of 1,756 voters believe the Morrison government needs to stay in the Paris agreement, despite Donald Trump’s decision to withdraw the US.
Security experts warn that Russia and China are both catching up and developing anti-satellite weapons capable of tripping up America’s strategic orbital foothold.The fourth thing to know about space power is, if America gives up its military dominance, expect its economic influence to wane as well.
And, if you’re a parent or teacher, see below for book recommendations for kids.Solar-powered schools and electric busesPhoto Illustration by The New York TimesSchools around the country are taking an interest in clean energy, putting solar panels on roofs and swapping diesel school buses for electric versions.But it’s not always easy for a school to go green.
The formulas are complex, but the bottom line is that reducing the emphasis on health makes it tougher to justify a rule.Last week the Trump administration took a crucial step toward de-emphasizing the life and health benefits in this calculus when the Environmental Protection Agency said it would rethink a major regulation that restricts mercury emissions by coal-burning power plants.
The central argument against adding cycle tracks with trees to urban streets asserts that cities need this space for parallel-parked cars.
Our research on Australian coal transition – based on contributions by researchers at the Australian National University and the University of Melbourne – looks into the prospects for coal use in Australia and for exports, and the experiences with local transition in the case of the Hazelwood power station closure.
The prime minister used a radio interview on Wednesday afternoon to declare “the business-as-usual model gets us there in a canter” – which contradicts advice from the Energy Security Board that says business as usual will mean the electricity sector will “fall short of the emissions reduction target of 26% below 2005 levels”.
That rule would have restricted coal plants’ emission of a different pollutant: carbon dioxide, one of the chief causes of global warming.At the time the Obama administration put forth the mercury regulations, which took more than 20 years to formulate, E.P.A. officials estimated they would save thousands of lives and return economic and health benefits many times their estimated $9.6 billion annual cost.While owners of coal plants fought the rule in the courts, most have since complied with regulation.
Over the past decade, more and more scientists have agreed that human impact on Earth is so significant that we have entered a completely new geological phase, called the Anthropocene, including a group convened to agree a formal definition.
It seems the devices’ graphic processing units, or GPUs, designed to render flying gore and mayhem, also ran physics simulations faster than the CPUs in ordinary computers.Today, researchers still use GPU chips, not just for modeling but for artificial intelligence.
“You would have expected the federal government to be taking the lead, but the federal government seems to be backing away every day from the commitments they’ve made.”“The biggest risk for us is not changing,” said Clint Bullock, chief executive of the Orlando Utilities Commission, the municipally owned power company.CreditEdward Linsmier for The New York TimesOrlando has set a goal of generating all of its energy from carbon-free sources by 2050.
On Sunday Birmingham said that Morrison “has made very clear we will continue to honour our commitments” including the Paris climate agreement, as Australia had done for the first and second round of Kyoto targets.
“The UK public deserves to have a watchdog with teeth that can enforce climate policy and ensure that our pledges become reality.”
Oh, and as Nathanel Johnson points out at Grist, environmentalists and activists have long argued over the distinction between "renewable," which is primarily solar and wind, and "clean," which includes other carbon-neutral-but-still-environmentally-problematic sources of juice like dams and nuclear power.The deeper problem is that merely farming the electrons isn’t enough.
Massive increases in computing power are allowing NIWA scientists to not only analyse more data, faster, but also to envisage completely new experiments. NIWA is part of a pilot project running incredibly sophisticated sensor networks on New Zealand farms, and analysing the data to improve on-farm decision making.
Next-Gen Nuclear Is Coming—If Society Wants ItArctic communities like this one are beginning to explore advanced nuclear reactors as a solution to their unique energy challenges.Third Way/GenslerThis story originally appeared on Grist and is part of the Climate Desk collaboration.Back in 2009, Simon Irish, an investment manager in New York, found the kind of opportunity that he thought could transform the world while — in the process — transforming dollars into riches.Irish saw that countries around the globe needed to build a boggling amount of clean-power projects to replace their fossil fuel infrastructure, while also providing enough energy for rising demand from China, India, and other rapidly growing countries.
If Germany Can't Quit Coal, Can Anyone Else?Germany's switch from black to brown (lignite) coal is making it tougher to meet carbon reduction goals.Dusan Bartolovic/Getty ImagesSometime next month, underground miners will dig Germany’s last ton of black coal, load it onto a conveyor belt, and whisk it a mile to the surface of the Ibbenbüren mining facility.
How could developed countries tweak their automobile policies to solve climate change?For Germany to meet emissions targets, “half of the people who now use their cars alone would have to switch to bicycles, public transport, or ride-sharing,” Heinrich Strößenreuther, a Berlin-based consultant for mobility strategies told YaleEnvironment360's Christian Schwägerl last fall.
