New metal 3D printer is 100x faster, 10x cheaper than existing laser technologies

Comments Off on New metal 3D printer is 100x faster, 10x cheaper than existing laser technologies

3D-metal printing could very easily become the go-to method for manufacturing around the world. Developed by Desktop Metal , it is reportedly faster, safer and cheaper than existing systems. Indeed, the company claims it can produce reliable metal printing up to 100 times faster than conventional manufacturing techniques with materials that cost 20 times less than existing laser technologies on the market. They also claim they can bring down costs to 10 times lower than normal. 3D printing has been a hot topic for years now, but the Massachusetts company is presenting something new — something capable of revolutionizing the manufacturing industry. Because of the new technology’s speed and efficiency, it’s even better than NASA and Boeing’s slow laser-melted metal printer and beats small design studios’ desktop 3D printers. Capable of using a variety of metal options — essentially, anything one can use in a Metal Injection Molding (MIM) system, it stands apart from other competitors. The engineering-driven startup was founded by several MIT professors and Emanuel Sachs, who holds patents in 3D printing dating back to 1989. Over the last few months, Desktop Metal raised more than $115 million (USD) and received backing from big players, including Google Ventures. Presently, the company is investing efforts in producing two systems: a studio system geared toward developing a rapid, cheap metal prototyping for engineering groups, and a production system for mass manufacture. According to New Atlas , the Studio printer “runs around and prints parts into layers of bound metal.” Then, the parts go into a “de-binding bath” that separates a substantial portion of the binding polymer. The parts then go into a sintering furnace. When the product is heated to just below the melting point, the binding agent burns off and a highly dense, sintered metal is produced. The system automatically manages the timing and temperature, depending on the design and the metals used. Support sections can be poked out with a screwdriver when the process is completed. Just don’t be surprised when the finished product is 15 percent smaller. The 3D-metal printer is 10 times cheaper than equivalent laser systems and is also less hazardous. Because there are no metal powders to deal with or dangerous lasers, they can easily — and safely — be installed in a home or office. In addition, it is very low-maintenance and does not require special support equipment or staff. All in all, the entire integrated system and the partnered software cost approximately $120,000 (USD). Though that price might seem steep, an equivalent laser system will run one more than $1 million (USD). And, that doesn’t take into account the safety and materials handling costs. The mass production system is built for speed and definitely delivers. It is faster than machining, casting, forging or other techniques, and each production printer can produce up to 500 cubic inches of complex parts per hour. As noted above, that is 100 times faster than a laser-based alternative — zero tools required. Related: MIT is 3D printing functional robots that could walk right off the printer To reach production speed with the mass system, a business would need four furnaces per printer. In contrast to the studio printer, the production machine uses powders which are bonded together during printing by spray-jetted droplets of a binder solution. They are low-cost in contrast to other systems (retail is estimated to be $360,000 USD) and are easily available — another advantage to the 3D-metal printing system. In fact, material costs are estimated to be 20 percent lower than other variations. As a result, printed metal parts may finally be economical enough to compete with traditional manufacturing processes. Though Desktop Metal is just getting started, many are predicting a 3D-metal printing revolution. The effects this technology will have on the economy will be revealed in time. + Desktop Metal Via New Atlas Images via Desktop Metal

Comments Off on Off-grid Tent House takes the roughing-it out of camping in New Zealand

For those that are looking to go  off-grid , but don’t want the fuss that comes with setting up camp, Architect Chris Tate ‘s Tent House is just the thing. Located on New Zealand’s remote Waiheke Island, the black A-Frame retreat was built into an area of undeveloped wetland on the island, letting guests get back to nature in contemporary style. The Auckland-based architect began to create the Tent House as personal studio for himself, but with a little tweaking of the design, the project developed into an unconventional space for anyone looking for an off-grid escape hidden deep in the forest. With all of the basic amenities of a swanky hotel, the space lets guests enjoy the beauty of nature without the hassle of setting up camp. Related: Tent cabin cluster blends perfectly into a Californian forest The A-frame structure is clad in black slats, blending it seamlessly into its natural surroundings. Inside, the one-bedroom, one-bathroom, 753-square-foot space is a beautiful minimalistic design. An all-glass entranceway leads into the open living area and the sleeping quarters are located on the mezzanine level. The glass facade floods the interior with natural light . In order to further connect the design into its surroundings, the front deck juts out into the vegetation. After the construction process was finished, the area around the house was carefully landscaped by planting hundreds of plants native to New Zealand. Since the project was completed, many native birds have returned to the area. The Tent House can be rented out for short-term rentals. + Tent House + Chris Tate Via Dwell Photography by Simon Devitt

Researchers turn recycled aluminum foil into cheaper, eco-friendlier biofuels

Comments Off on Researchers turn recycled aluminum foil into cheaper, eco-friendlier biofuels

Don’t toss your bagel wrapper in the trash just yet; scientists at Queen’s University Belfast in Northern Ireland say they have discovered a way to turn used aluminum foil into a catalyst to create cheaper, eco-friendlier biofuels . Working with engineers from the university, Ahmed Osman, an early career researcher at the school of chemistry and chemical engineering, has developed a technique that extracts 100 percent pure single crystals of aluminum salts from contaminated foil, without creating harmful emissions or waste. The salts can be used to kickstart the preparation of alumina catalyst, which can then be used to produce dimethyl ether, a nontoxic, clean-burning fuel that is typically manufactured from plant-based biomass. This process has a couple of distinct advantages, Osman said. Current methods of creating this type of alumina involves bauxite ore, the mining of which causes appreciable environmental damage in countries such as West Africa, the West Indies, and Australia. Related: Breakthrough algae strain produces twice as much biofuel There’s also the abundance of aluminum foil packaging waste. Because grease in used foil can muck up recycling equipment, nearly 20,000 tons of the stuff—enough to reach the moon and back—is either landfilled or incinerated in the United Kingdom alone. Osman plans to fine-tune his research so he can explore opportunities for commercialization, whether for biofuel production or the use of the modified alumina catalyst in the catalytic converters of natural-gas vehicles. “This breakthrough is significant as not only is the alumina more pure than its commercial counterpart, it could also reduce the amount of aluminum foil going to landfill while also sidestepping the environmental damage associated with mining bauxite,” Osman said in a statement . + Queen’s University Belfast Via New Atlas Photo by blikss/Flickr

Comments Off on Google enters nuclear fusion clean-energy race

Nuclear fusion is the holy grail of sustainable energy — a potentially unlimited source of pollution-free energy that can power the world. No greenhouse gas emissions. Only helium and a neutron are produced. Now Google has jumped into the race to commercialize nuclear fusion technology, teaming up with California-based fusion company Tri Alpha Energy to develop a new computer algorithim that optimises plasma — an ionized gas that conducts electricity. “Google is always interested in solving complex engineering problems, and few are more complex than fusion,” wrote Ted Baltz, senior staff software engineer, Google Accelerated Science Team, on Google’s research blog . “Physicists have been trying since the 1950s to control the fusion of hydrogen atoms into helium, which is the same process that powers the Sun. The key to harnessing this power is to confine hydrogen plasmas for long enough to get more energy out from fusion reactions than was put in. This point is called ‘breakeven.’ If it works, it would represent a technological breakthrough, and could provide an abundant source of zero-carbon energy.” Related: These mini spherical reactors could help scale fusion energy by 2030 The research was published Tuesday in the journal Scientific Reports . The Optometrist Algorithm achieved a 50 percent reduction in the energy loss rate and an increase in ion temperature and total plasma energy. Other private and public entities are racing to become the first to bring nuclear fusion to scale. Experimental testing includes the Iter project in France, the Wendelstein 7-X (W7X) stellarator in Germany and the Tokamak ST40 reactor in the UK. General Fusion , a Canadian company, is also working to develop nuclear fusion technology. + Tri Alpha Energy + Achievement of Sustained Net Plasma Heating in a Fusion Experiment with the Optometrist Algorithm Via The Guardian Images via Tri Alpha Energy , Google Research Blog

Comments Off on Affordable home geothermal energy systems come to upstate New York

When you think of home renewable power systems, geothermal energy probably isn’t the first source that springs to mind. But new company Dandelion , which starts after time at Google’s moonshot factory X , aims to power houses with the clean , free source “right under our feet.” They’re offering their systems beginning in northeastern America. The Dandelion team launched their company independent of Alphabet this month, offering geothermal heating and cooling for homes. They come in and replace cooling, heating, and hot water equipment with their geothermal systems, including underground pipes and a heat pump, which gather energy from the earth. The company describes geothermal cooling and heating as the most efficient method of such climate control for the home. Related: St. Patrick’s Cathedral unveils state-of-the-art geothermal plant Affordability was one of Dandelion’s main goals. They say many homes haven’t yet adopted geothermal systems due to the hefty cost associated with setup. In contrast, Dandelion’s system costs $20,000. On their website they say they’ve partnered with a leading financing company to install the systems with zero costs upfront followed by low monthly payments. The company also designed a better drill to install the systems. In the past, geothermal systems were installed with a wide drill that was intended for water wells more than 1,000 feet into the ground. The Dandelion team designed a slender drill that can create one or two deep holes a few inches wide – with less waste. Their new drill lets them put in ground loops in under one day. Overall, putting in their geothermal systems takes two to three days. Dandelion’s heat pumps will last around 25 years, while the closed-loop piping can last for a minimum of 50. The system comes with a smart thermostat enabling homeowners to regulate the temperature inside. The team is starting with 11 counties in New York – they say regions with cold winters and hot summers are ideal for home geothermal systems. + Dandelion Via Kathy Hannun on Medium Images via Dandelion Facebook and Dandelion

Comments Off on Indian Railways launches first train with solar-powered coaches

Train travel in India just got a little greener. Last week Indian Railways rolled out their first train outfitted with rooftop solar panels – in the Delhi area notorious for its pollution . The solar panels will completely power fans, lighting, and display systems in the coaches. The government expects the move will save them around 5,547 gallons of diesel every single year. The train, a 1600 HP DEMU, is just the first of several more trains with solar-powered coaches to come. Indian Railways will install solar panels on 24 other trains in the upcoming six months. In the past, a diesel-fueled generator provided electricity for a train’s lighting and fans, but the new solar system includes a smart MPPT inverter so these features can be cleanly powered even during the night. According to Indian Railways, the solar panels will slash carbon dioxide generation by nine metric tons per coach per year. Related: Indian Railways installing rooftop solar panels on 250 trains 16 solar panels generating 300 watts each offer a 4.5 kilowatt peak capacity for each coach. The system can generate around 20 kilowatt-hours of clean power per day. A 120 AH battery system will store excess power generated during peak hours. Minister of Railways Shri Suresh Prabhakar Prabhu said the railways are committed to conserving the environment and using more clean energy . The government’s press release on the trains pointed to other measures the railways have taken to become more environmentally friendly, such as the use of bio-toilets , biofuels, and wind energy. Jakson Engineers, under the guidance of the Indian Railways Organization for Alternative Fuels (IROAF), developed the new train solar system. Managing director Sundeep Gupta told Business Standard is was no easy feat to attach solar panels to trains that will move at speeds of 80 kilometers per hour, which is around 50 miles per hour. The train has a lifetime of around 25 years. Via Quartz India and Government of India Images via screenshot and Ministry of Railways on Twitter

Google requested to label anti-fracking websites as fake news

Comments Off on Google requested to label anti-fracking websites as fake news

Following the results of the 2016 U.S. Presidential election , search engine website Google rewrote its engine algorithm to bury “fake news.” They were consequently blamed for Hillary Clinton’s loss and the “propaganda” which supposedly defamed President Trump . Since then, the phrase “ fake news ” has been a readily-used one. And, members of the industry-funded Texans for Natural Gas are taking advantage of it by urging Google to include anti- fracking websites in its list of sources that lack integrity and accuracy. In an open letter to Google which was published on Monday, the group wrote , “We believe many of the most prominent anti- fracking websites have content that is misleading, false, or offensive – if not all three. As a result, we urge you to consider purging or demoting these websites from your algorithm, which in turn will encourage a more honest public discussion about hydraulic fracturing , and oil and natural gas development in general.” Bloomberg reported in April that due to immense pressure to eliminate fake news , or what the company calls “low-quality” content, Google raters now “assess search results — to flag web pages that host hoaxes, conspiracy theories and what the company calls ‘low-quality’ content.” The process in question is hydraulic fracturing ( fracking ), which involves injecting large amounts of water, mixed with sand and an assortment of chemicals, deep into the ground to unlock reserves of oil and natural gas . The drilling technique is responsible for igniting the energy boom, but many environmentalists view it as a threat to the planet. This is because the process may contaminate groundwater, pollute the air and threaten wildlands. Additionally, some scientists believe fracking causes earthquakes, as Inhabitat previously reported . Related: EPA finally admits fracking contaminates drinking water Though the Environmental Protection Agency (EPA) did announce in 2015 that no widespread evidence was found proving that fracking contaminates groundwater, it later reversed its decision. In late 2016, the EPA concluded that there is evidence that fracking has contaminated drinking water in all stages of the process. Because of these findings, many citizens are adamant that they deserve the right to be skeptical of the process, especially considering the country’s reliance on fossil fuels is propelling climate change . Texans for Natural Gas believe otherwise, however. The group wrote to Google, “Claims made by the radical environmentalist campaign against hydraulic fracturing are protected by the First Amendment.” “Groups that wish to peddle misleading information about oil and natural gas are fully within their rights to do so. Many of the groups engaging in anti-fracking advocacy have devoted significant resources to Search Engine Optimization (SEO), and as a result they receive significant web traffic,” they added. “But that is no reason for Google to reward such misinformation with its powerful search engine. We urge you consider adding these groups’ websites to your review of fake news and the kinds of content that you do not wish to promote.” Via The Daily Signal Images via Bloomberg

Comments Off on Germany just generated a record 85% of its energy from renewable sources

Germany has outdone itself yet again when it comes to clean energy . From April 30 through May 1, the country set a national record by generating 85% of all its energy needs using renewable wind, solar, biomass, and hydroelectric power. And this isn’t just an anomaly – experts believe that this will be the new normal for Germany by 2030. “Most of Germany’s coal-fired power stations were not even operating on Sunday, April 30th, with renewable sources accounting for 85 per cent of electricity across the country. Nuclear power sources, which are planned to be completely phased out by 2022, were also severely reduced,” said Patrick Graichen of Agora Energiewende Initiative . Related: Google’s Project Sunroof expands to 7 million homes in Germany Germany has worked hard to invest in clean energy sources under Angela Merkel , a vocal supporter of renewable energy. It has paid off. In addition to record-breaking weekends like the one on April 30, more and more energy is coming from renewables. In March, the country average 40% energy from green sources. via Clean Technica images via Flickr ( 1 , 2 )
