Revolutionary solar paint creates endless energy from water vapor

Researchers at  RMIT University in Melbourne have created a revolutionary new  solar paint that can be used to produce endless amounts of clean energy. The innovate paint draws moisture from the air and splits it into oxygen and hydrogen. As a result, hydrogen can be captured as a clean fuel source. The paint contains a recently-developed compound that looks and feels like silica gel — commonly used in sachets to absorb moisture and keep food, electronics, and medicine dry — but acts like a semiconductor. Additionally, the synthetic molybdenum-sulphide material catalysis the splitting of water atoms into hydrogen and oxygen. The researchers’ discovery was recently  published  in Science Daily. Lead researcher Dr. Torben Daeneke elaborated on the invention, saying, “We found that mixing the compound with titanium oxide particles leads to a sunlight-absorbing paint that produces hydrogen fuel from solar energy and moist air.” According to colleague Professor Kourosh Kalantar-zadeh, hydrogen is the cleanest source of energy on the planet and can be used in fuel cells in addition to conventional combustion engines as an alternative to fossil fuels . Because of this, it is accurate to say that the development of the solar paint will have grand implications.

This means there is no need for filtered or clean water to feed the system. And, any location that has water vapor in the air — including remote areas — can produce fuel. “This system can also be used in very dry but hot climates near oceans. The sea water is evaporated by the hot sunlight and the vapour can then be absorbed to produce fuel,” said Kourosh Kalantar-zadeh. “This is an extraordinary concept — making fuel from the sun and water vapour in the air.” Via Science Daily Image via UnderstandSolar

Comments Off on Scientists say we have 10 years to save Earth

Time is running out to protect Earth from the disastrous effects of climate change . An international team of eight researchers said we have just 10 years to save the planet. But their news isn’t all bad: they’ve come up with a model for balancing carbon dioxide emissions with carbon sinks , like forests, to keep temperatures from passing the 1.5 degree Celsius mark widely considered safe for life as we know it. Scientists say if the world actually intends to stick to the Paris agreement , the next decade will be critical. They say there are two ways to reduce carbon emissions: by slashing the emissions we humans produce and by restoring carbon sinks, and it’s time to take action on both. They detailed their plan in a Nature Communications study, published online yesterday. Related: Scientists say Trump’s presidency could lead to a “game over” scenario for the planet World Bank consultant Brian Walsh, who led the study while doing research for the Austria-based International Institute for Applied Systems Analysis (IIASA), said they scrutinized carbon emissions from fossil fuels , agriculture, food production, bioenergy, and land use. They also accounted for natural ecosystems taking in carbon emissions to determine where they originate and where they go. Here’s the recommendation: we must reduce fossil fuel use to the point where it’s under 25 percent of the global energy supply by 2100; it’s at 95 percent right now. And we need to reduce deforestation to attain a 42 percent decrease in emissions by 2100. Renewable energy is also part of the answer. The researchers considered four scenarios for energy development in the future. A high-renewable scenario would see wind, solar, and bioenergy use increase by five percent a year so emissions would peak by 2022. Even that pathway would lead to a 2.5 degrees Celsius temperature increase if we don’t also employ negative emissions technologies. IIASA Energy Program Director and co-author Keywan Riahi said, “Earlier work on mitigation strategies by IIASA has shown the importance of demand-side measures, including efficiency, conservation , and behavioral change. Success in these areas may explain the difference between reaching 1.5 degrees Celsius instead of 2 degrees Celsius.” Via the International Institute for Applied Systems Analysis and EcoWatch Images via Wikimedia Commons and Pixabay

Clean energy jobs outnumber fossil fuel jobs in most US states

Comments Off on Clean energy jobs outnumber fossil fuel jobs in most US states

Clean energy is increasingly providing work for people across the United States, contrary to what the president might think, and a new Sierra Club report reveals just how much of an impact on the economy it has made. Renewable energy jobs now exceed jobs in coal, oil, and gas in 41 American states and Washington, D.C., according to the report. Sierra Club drew on 2017 Department of Energy jobs data to discover clean energy jobs exceed those in fossil fuels by more than 2.5 to one. The energy jobs of the future, including those in wind , solar , energy efficiency , battery storage , and smart grid technology, already exceed coal, oil, and gas jobs nationally, including positions in extraction, mining, and power generation. According to Sierra Club’s analysis, clean energy jobs outnumber fossil fuel jobs by over 2.5 to one, and exceed gas and coal jobs by five to one. While only nine states have more fossil fuel than clean energy jobs, just six states have more jobs in coal and gas, according to the report. Related: Solar power now provides twice as many jobs as coal in U.S. In a statement Sierra Club Executive Director Michael Brune said, “Right now, clean energy jobs already overwhelm dirty fuels in nearly every state across America, and that growth is only going to continue as clean energy keeps getting more affordable and accessible by the day. These facts make it clear that Donald Trump is attacking clean energy jobs purely in order to boost the profits of fossil fuel billionaires.” If Trump really wants to increase jobs as he claims – and not just fill the pockets of his fossil fuel friends – he should look no further than renewable energy. The report concludes policies to invest in and incentivize clean energy could generate millions of new jobs across America, more than could be created in the fossil fuel sector. Sierra Club also said the clean energy transition should benefit everyone; this means putting first communities and workers who depended on fossil fuels in the past.

Scientists turn spinach into human heart tissue

Comments Off on Scientists turn spinach into human heart tissue

Popeye was right: spinach really is good for the muscles, and not just the ones in your biceps. In fact, scientists have discovered a way to use the leafy stuff, which has a vascular system not dissimilar to ours, to grow layers of working heart muscle, according to a paper published this month in the journal Biomaterials . The new technique, a collaboration between Worcester Polytechnic Institute , the University of Wisconsin-Madison , and Arkansas State University-Jonesboro , marks a breakthrough in the field of human tissue regeneration, which has hitherto been stymied by scale. To wit, although current bioengineering methods can recreate cellular scaffolding on a large scope, fabricating branching networks of tiny blood vessels has proven far trickier. But then scientists noticed that plants and animals evolved parallel means of distributing water and nutrients to their respective cells. “Plants and animals exploit fundamentally different approaches to transporting fluids, chemicals, and macromolecules, yet there are surprising similarities in their vascular network structures,” the authors wrote. “The development of decellularized plants for scaffolding opens up the potential for a new branch of science that investigates the mimicry between plant and animal.” To test their theory, the researchers stripped a bunch of spinach leaves of their cells, leaving behind a network of cellulose. They then seeded the spinach veins with beating human-heart cells. With the leaf fully networked, the team pumped fluids and microbeads through their pint-size proto-heart, mimicking the flow of human cells through our own arterial system. Related: Engineers build artificial muscles from onion skin and gold So far, so successful. “We have a lot more work to do, but so far this is very promising,” said Glenn Gaudette, professor of biomedical engineering at WPI and corresponding author of the paper. And it’s not just spinach that’s up for the job. Other decellularized plants could help deliver oxygen to damaged tissue in victims of heart attacks or other kinds of cardiac trauma. Even better, bioengineers could tweak different plant species to repair a range of tissues in the body. Spinach might work best for highly vascularized cardiac tissue, for instance, but the cylindrical hollow structure of something like jewelweed might be more appropriate for an arterial graft. Similarly, the vascular columns of wood could one day play a role in healing human bones. “Adapting abundant plants that farmers have been cultivating for thousands of years for use in tissue engineering could solve a host of problems limiting the field,” Gaudette added. + Worchester Polytechnic Institute Via National Geographic

Standing Rock protesters evicted by police at gunpoint

Comments Off on Standing Rock protesters evicted by police at gunpoint

Yesterday police in riot gear evicted Standing Rock protesters after an evacuation deadline passed. Though the majority of demonstrators left the Oceti Sakowin camp before the February 22nd deadline, about 50 Dakota Access Pipeline protesters remained. Most of these passive resistors – including veterans and tribal elders – were arrested at gunpoint by officers clad in full riot gear. The raid was livestreamed on Facebook over the course of 4 hours throughout the day. The initial evacuation was ordered on the pretext of protecting demonstrators from seasonal floods, which could potentially affect the area. While this is certainly a legitimate concern, the fact that over 200 police officers were sent to clear the area, armed with rifles and military-style equipment, makes it clear that the protesters’ safety isn’t Governor Doug Burgam’s main priority. Related: Judge throws out request to halt Dakota Access Pipeline construction Morton County Sheriff Kyle Kirchmeier told ABC News in a statement, “I am very happy to say that we finally introduced rule of law in the Oceti camp. I am hopeful that this announcement brings us closer to finality in what has been an incredibly challenging time for our citizens and law enforcement professionals. Having dealt with riots, violence, trespassing and property crimes, the people of Morton County are looking forward to getting back to their normal lives.” For many of the Standing Rock Sioux tribe members, there is no “normal life” to get back to. Now that the pipeline construction is slated to go forward , they live in fear that a catastrophic oil spill could put their community’s access to clean water at peril. The “violence, trespassing, and property crimes” they’ve been subject to at the hands of police in the past year include being attacked by security dogs , blasted with water cannons at hypothermia-inducing temperatures, and having land they claim was granted to them as part of a 1851 treaty given away to oil companies by the federal government. Related: Trump claims he received no calls about the Keystone and Dakota pipelines Though the protests are Standing Rock have been ended by force, the movement to force banks to stop supporting the Dakota Access Pipeline continues. Oakland , Los Angeles , and New York City are just a few of the local governments urged to divest from the pipeline. Seattle has already voted to end all financial support of the project by moving $3 billion of the city’s funds from Wells Fargo.

America will soon surpass the clean energy standards Trump wants to kill

Comments Off on America will soon surpass the clean energy standards Trump wants to kill

Barack Obama’s Clean Power Plan , first announced in 2015, caused no end of political controversy in conservative circles for its ambitious carbon-cutting goals. By February 2016, the Supreme Court halted enforcement of the regulations due to complaints from 29 mostly Republican-led states. Opponents argued that the plan would cause massive layoffs in the energy sector. Now, a new report shows the US is actually poised to surpass the Clean Power Plan’s federal requirements – quite a different picture from the one Trump and his cabinet are painting. The new data comes from the 2017 Sustainable Energy in America Factbook , published by Bloomberg New Energy Finance and the Business Council for Sustainable Energy. The report notes: “Within the power sector, the progress is even more noteworthy: in 2016, greenhouse gas emissions from US power plants dropped 5.3% in just one year. Since 2005, the power sector has shrunk its carbon footprint by 24% – in other words, the US is 75% of the way to the Clean Power Plan’s “32% by 2030” headline target, with 14 additional years left to go.” Part of the reason for the lowered emissions is the fact that coal is losing its share of the energy market. Right now it only comprises 30% of the electricity grid in the US – the lowest percentage in the last 70 years. The rise in solar energy is another contributing factor – the solar industry grew by 51,000 jobs last year and seemed poised to continue growing until at least 2022, with the encouragement of the solar energy tax credit. Related: Supreme Court freezes Obama’s plan to cut CO2 emissions This report shows that the transformation in America’s energy market was in effect before the CPP was even on the table. While Obama’s clean energy policies surely accelerated it and made it easier for businesses to make the switch to renewable energy, the change was well underway. Trump’s administration may be expressing interest in repealing the rule , but it’s unlikely to stop the clean energy revolution that’s already underway.

Comments Off on Army approves Dakota Access Pipeline route – and construction could begin immediately

In a surprise move, the US Army Corps of Engineers just approved construction on the final 1.5 miles of the Dakota Access Pipeline . The move cut short a public comment period and environmental impact assessment that was supposed to last two weeks – the Army was originally supposed to accept comments through February 20th, but it expedited the process under the direction of Donald Trump . The accelerated timeline makes legal challenges to the pipeline extremely difficult. The agency has also announced it’s planning to waive its usual policy of waiting 14 days after notifying Congress of the decision to grant an easement. Instead, the easement could be granted within 24 hours, allowing Energy Transfer Partners to begin construction immediately. Due to the nature of the project, it’s not necessary for the company to apply for a separate construction license. Related: 76 water protectors arrested at Standing Rock The Standing Rock Sioux Tribe reports that it plans to file a lawsuit and ask for a temporary restraining order to halt construction while the decision’s legal standing undergoes a review. The protestors are also coordinating an international day of action to stand against the decision. In the past, police have soaked Standing Rock protectors with water cannons in freezing conditions, attacked them with dogs , and early in February 76 protestors were arrested during a raid on a new camp at Standing Rock.
