Comments Off on Hundreds of ancient earthworks similar to Stonehenge found in the Amazon

For hundreds of years, the Amazon rainforest concealed over 450 massive, mysterious earthworks similar to those in Stonehenge . As a result of deforestation , researchers were able to catch a glimpse of the baffling geometrical geoglyphs in Brazil’s Acre state. The 2,000-year-old earthworks reveal a wealth of information we didn’t know before about how ancient people managed the rainforest . Many people used to think the Amazon rainforest ecosystem remained largely untouched by humans in the past, an idea challenged by the recent discovery of these huge earthworks. Led by Jennifer Watling of the University of São Paulo and the University of Exeter , a team reconstructed fire and vegetation history over 6,000 years near two of the geoglyphs, and found humans actually changed the bamboo forests heavily for millennia. They temporarily cleared areas to build the earthworks. Related: Archaeologists reveal fresh details about 4,500-year-old “New Stonehenge” As researchers didn’t find many artifacts around the earthworks, the sites probably weren’t villages, and their layout prompts researchers to think they weren’t used for defense. Instead, the ancient geoglyphs may have been utilized only once in a while for ritual gatherings. Watling cautions against excusing rampant deforestation based on this new information. Her team’s research shows while ancient people altered the rainforest, they did not employ long term, large-scale deforestation as happens today, or burn swaths of forest. Instead they employed ancient agroforestry practices and focused on economically valuable trees like palms to create what the University of Exeter describes as a prehistoric supermarket of products from the forest. Watling said, “Our evidence that Amazonian forests have been managed by indigenous peoples long before European Contact should not be cited as justification for the destructive, unsustainable land-use practiced today. It should instead serve to highlight the ingenuity of past subsistence regimes that did not lead to forest degradation, and the importance of indigenous knowledge for finding more sustainable land use alternatives.” Nine other researchers from institutions in Brazil, the United Kingdom, and Canada joined Watling in the research; the journal Proceedings of the National Academy of Sciences published their study online this month.

First Wattway solar road pilot in US pops up in rural Georgia

Comments Off on First Wattway solar road pilot in US pops up in rural Georgia

The first Wattway solar road pilot in America has popped up in rural west Georgia . The Ray C. Anderson Foundation , named for sustainable manufacturing pioneer Ray Anderson, is testing renewable technologies along an 18-mile stretch of road, and recently installed 538 square feet of Colas ‘ Wattway solar road system near the border between Georgia and Alabama. Part of Georgia’s Interstate 85 was named for Anderson, but as over five million tons of carbon dioxide are emitted yearly on that road portion alone, Anderson’s family felt placing his name there didn’t honor his legacy, and began to look into renewable technologies to clear the air – so to speak. Thus began The Ray , an 18-mile living laboratory for clean technologies, including not only the solar roads, but also a solar-powered electric vehicle charging station , and WheelRight , a system people can drive over to test their tire pressure, which could lead to improved fuel inefficiency.

According to Wattway by Colas, the average expected output for the 538-square-meter pilot is anticipated to be 7,000 kilowatt-hours per year, which will help power the center. And these technologies are just the beginning. The foundation will also construct bioswales , or shallow drainage ditches filled with native Georgia plants to capture pollutants during rain. In a right-of-way space, they’ll build a one megawatt solar installation . They’re working with the Georgia Department of Transportation to bring such ideas to life along the 18-mile road stretch. Not only will several of their projects beautify the highway, but will generate clean energy and bring in money for investors. And other parts of the state have shown interest in building their own Wattway roads. The Ray executive director Allie Kelly dreams of a day when highways will “serve as a power grid for the future,” but she believes that day is coming sooner than we may think. She told Curbed, “We’re at a tipping point in transportation . In five to ten years, we won’t remember a time when we invested a dime in infrastructure spending for a road that only did one thing.” + The Ray + Wattway by Colas Via Curbed Images © Valerie Bennett and via The Ray

Comments Off on Tiny TigerMoth Camper generates power while being towed

Taxa Outdoors’ tow camper, the TigerMoth , is a compact home on wheels geared towards traveling adventurers. The lightweight camper sleeps two, has LED lights, and even better, comes with a built-in electrical system that generates energy while being towed. The camper’s battery can store energy for at least seven days, making off-grid living easier than ever before. Although certainly compact, the camper sleeps two comfortably and thanks to its lightweight size of just 900 pounds, can be towed virtually anywhere. The unique side latch allows for easy access and the large window allows for amazing views and air circulation. Built with adventurers in mind, the small structure has a roof rack system for bikes or kayaks, a tongue-mounted toolbox, and a roof cargo deck for additional gear storage. Related: Traveling family renovates old school bus as both solar-powered home and hostel The camper’s tow vehicle connection recharges the battery while on the road, providing enough electricity for at least seven days of off-grid living . Although solar panels have to be ordered, the camper roof is pre-wired for installation. As far as the basic amenities go, the tiny camper can sleep two people comfortably and comes with LED lighting installed in the kitchen area and sleeping area. There is 5.5 square feet of countertop for food preparation or work space. Along with various hooks and bungees, two large cubbies provide extra storage space. + Taca Outdoors

Comments Off on Bill Gates warns against climate-change denial

Billionaire philanthropist Bill Gates recently spoke out against denying climate change during a student question-and-answer session at Columbia University in New York City earlier this month. Joined by voluntary tax-information sharer and fellow monied person Warren Buffett , the Microsoft founder also called for greater innovation in clean energy. He said, “Certain topics are so complicated like climate change that to really get a broad understanding is a bit difficult and particularly when people take that complexity and create uncertainty about it”. And Gates is more than happy to put his money where his mouth is. In December, he and a team of investors said they would pump more than $1 billion into Breakthrough Energy Ventures , a fund that invests in technologies that will curtail the planet’s greenhouse-gas emissions. Related: Bill Gates pledges $2 billion to renewable energy research We need to find energy that’s “reliable, cheap, and clean,” he said, before promising that “the innovations there will be profound.” He added, “There are many paths to get to where we need to go”. Perhaps another billionaire we know should pay attention? Photo by DFID Via U.S.A. Today
