Comments Off on New photosynthesis machine is twice as efficient at creating hydrogen fuel

Researchers at the University of Michigan and McGill University in Montreal have created a device that uses sunlight to efficiently split fresh or salt water into hydrogen that may be used in fuel cells. The new machine, which mimics the process of photosynthesis , is capable of producing hydrogen fuel at twice the efficiency of previous technologies. Producing only water as an emission, hydrogen is the cleanest burning fuel. However, its production has historically not been environmentally friendly or energy efficient. This new device may change all that, paving the way to a cleaner energy future. “If we can directly store solar energy as a chemical fuel, like what nature does with photosynthesis, we could solve a fundamental challenge of renewable energy,” said lead researcher Zetian Mi . Unlike solar panels, which can only store energy if they are attached to a battery, the artificial photosynthesis device uses splits water to store solar energy as hydrogen fuel. Despite this fundamental difference from solar panels , the device is made from the same materials, such as silicon and gallium nitride, which is also found in LEDs. Related: Scientists create world’s first solar fuel reactor that works at night Small towers of gallium nitride generate an electric field to turn photons into free charges, which divide water into its two component elements, oxygen and hydrogen. In contrast with previous solar splitters, which had only reached 1 percent efficiency, Mi’s team managed to achieve a 3 percent solar-to-hydrogen efficiency. “Although the 3 percent efficiency might seem low, when put in the context of the 40 years of research on this process, it’s actually a big breakthrough,” Mi said. “Natural photosynthesis, depending how you calculate it, has an efficiency of about 0.6 percent.” The device, further developed, may even be able to pull carbon dioxide from the atmosphere, potentially alleviating the impact of climate change .

Anheuser-Busch orders 800 hydrogen-electric semi trucks from Tesla competitor Nikola

Comments Off on Anheuser-Busch orders 800 hydrogen-electric semi trucks from Tesla competitor Nikola

Tesla’s made headlines with its electric Semi truck — but Anheuser-Busch is betting big on their competitor, the Nikola Motor Company . The beer company placed an order for as many as 800 hydrogen-electric semi trucks just days after Nikola sued Tesla for patent infringement. Nikola says their zero emissions trucks boast a 500- to 1,200-mile range – plenty to haul Anheuser-Busch’s beer around the country. Anheuser-Busch’s goal is to convert its dedicated long-haul fleet over to renewably-powered vehicles by 2025. 800 hydrogen-electric semi trucks could help them reach that goal. Nikola said their trucks could be integrated into the brewing company’s fleet in 2020. Features of the truck include the ability to refuel in around 20 minutes, and a surround viewing system for improved safety. Nikola could charge around $400,000 on average for their trucks, which are as yet in the prototype phase, according to Reuters . Related: Self-driving semi-truck makes the first ever autonomous beer run The trucks could help the beer company attain sustainability goals; Nikola said, “Once fully implemented, the carbon reductions gained from these 800 trucks will reduce the brewer’s carbon emissions from logistics by more than 18 percent — equivalent to taking more than 13,000 passenger vehicles off the road annually.” Nikola says on their website they plan to create the world’s largest hydrogen network, and CEO Trevor Milton said they’re excited to partner with Anheuser-Busch to bring this network to the United States. He said in the statement, “By 2028, we anticipate having over 700 hydrogen stations across the USA and Canada. With nearly nine billion dollars in pre-order reservations, we are building to order, not speculation, and are very excited for what’s to come.” Reuters described that last statement as a not-so-veiled jab at Tesla — people have questioned the Tesla Semi’s cost, range, and payload. The expected base prices for Tesla’s Semi are $150,000 for a 300-mile-range truck or $180,000 for a 500-mile-range truck. Anheuser-Busch did place 40 reservations for the Tesla Semi. Although Nikola and Tesla are both named after inventor Nikola Tesla, the companies aren’t exactly on good terms — Nikola recently sued Tesla over design patent infringements. Elon Musk referred to the allegation as a “laughable lawsuit.” + Nikola Motor Company Via Reuters and Mashable Images via Nikola Motor Company

Much like the Guggenheim Museums around the world, a new art gallery founded by the great-grandson of Peggy Guggenheim is a true architectural showstopper. Santiago Rumney Guggenheim commissioned designer Jorge Eduardo Neira Sterkel to create IK LAB , a stunning arts gallery that opened late last month in Tulum, Mexico. Topped with a curved timber canopy, the nature-inspired space is located within the eco-friendly Azulik resort. Upon entering, visitors are asked to slip off their shoes and “to interact with the floor as a living organism,” made from woven jungle vines that seamlessly flow into walls and ceilings made with smooth curved concrete and locally sourced wood. No trees were cut in the process of building and the organic structure is lifted off the ground to minimize site impact. Natural light filters into the building through spaced-out timber elements and large openings in the walls reinforced by transparent fiberglass . In addition to framed views of the jungle outside, plants grow inside the art gallery as well. Related: World’s first porcelain courtyard opens at London’s V&A Museum “This majestic space redefines the traditional white-cube, gallery-visiting experience, instead fortifying the organic relationship between art and its physical surroundings,” IK LAB said in a statement. The inaugural exhibition, curated by Santiago R. Guggenheim, is titled “Alignments.” It features works by Tatiana Trouvé, Artur Lescher and Margo Trushina. + IK LAB Via Dezeen Images by Fernando Artigas

CO2 levels averaged above 410 ppm ‘for the first time in recorded history’ in April

Comments Off on CO2 levels averaged above 410 ppm ‘for the first time in recorded history’ in April

Just over a year ago, atmospheric carbon dioxide (CO2) levels hit 410 parts per million (ppm) for the first time in millions of years. And we just hit another worrying threshold in April: levels averaged higher than 410 ppm throughout the whole month for the first time. Geochemist Ralph Keeling said , “We keep burning fossil fuels . Carbon dioxide keeps building up in the air. It’s essentially as simple as that.” The Keeling Curve , a daily record of atmospheric CO2 levels made at the Mauna Loa Observatory, started in 1958. Back then measurements were around 315 ppm. 60 years later, we’ve passed the 410 ppm threshold, and in April, the average concentration was 410.31 ppm. According to the Scripps Institution of Oceanography, “This marks the first time in the history of the Mauna Loa record that a monthly average has exceeded 410 ppm.” Today marks the 60th anniversary of the #KeelingCurve , a daily record of carbon dioxide levels in the atmosphere. This record is considered the foundation of modern climate change research. pic.twitter.com/XJgGIj8Z1S — Scripps Oceanography (@Scripps_Ocean) March 29, 2018 Related: CO2 levels just reached 410 ppm — the highest in millions of years The Washington Post pointed out CO2 levels have hit 400 ppm in the past — such as over three million years ago in the mid-Pliocene warm period. But the Pliocene level “was sustained over long periods of time, whereas today the global CO2 concentration is increasing rapidly,” according to scientists in the Fourth National Climate Assessment, Volume 1 , a 2017 federal report. Before the beginning of the Industrial Revolution, CO2 levels fluctuated over thousands of years, but according to the institution, never exceeded 300 ppm once in the past 800,000 years. Around 1880, CO2 levels were about 280 ppm. Today, they’re around 46 percent higher. Climate scientist Katharine Hayhoe said about the milestone on Twitter , “It’s as if we discovered that something we eat every day is causing our body to run a fever and develop all kinds of harmful symptoms — and instead of cutting back, we right keep on eating it, more and more. If that isn’t alarming, I don’t know what is.” + Scripps Institution of Oceanography Via The Washington Post Images via Devin McGloin on Unsplash and Nik Shuliahin on Unsplash
