The discovery of a 14,000-year-old ancient village in Canada could forever alter our understanding of early civilization in North America. Researchers estimate the settlement is way older than the Giza pyramids, and have found artifacts dating all the way back to the Ice Age . The village is one of the oldest human settlements we’ve ever uncovered in North America – and lines up with the oral history of the Heiltsuk Nation. Researchers from the Hakai Institute and University of Victoria , with local First Nations members, unearthed revealing artifacts on Triquet Island, around 310 miles northwest of Victoria, Canada. They’ve found fish hooks, spears, and tools to ignite fires. Thanks to the discovery of the ancient village last year, researchers now think a massive human migration may have happened along British Columbia’s coastline.

But the recent discovery suggests people moved down the coast possibly in boats instead; the coastal route likely came before the inland route. University of Victoria PhD student Alisha Gauvreau, who was part of the excavation, told CTV News Vancouver Island, “I remember when we get [sic] the dates back and we just kind of sat there going, holy moly, this is old. What this is doing is just changing our idea of the way in which North America was first peopled.” The find fits right in with the oral history of a First Nations government in British Columbia, the Heiltsuk Nation. For generations they’ve told stories of ancient coastal villages. William Housty of Heiltsuk Nation told CTV News Vancouver Island, “To think about how these stories survived all of that, only to be supported by this archaeological evidence is just amazing.” Via CTV News Vancouver Island , The Independent , and IFL Science Images via screenshot and Hakai Institute Twitter

World’s first full-size IBC bifacial solar module takes in light from both sides

What if both sides of a solar panel could take in light? That’s the idea pursued by researchers at the Solar Energy Research Institute of Singapore (SERIS), National University of Singapore , and Germany’s International Solar Energy Research Center Konstanz . They’ve succeeded in developing and fabricating the first full-size interdigitated back contact (IBC) bifacial solar module in the world. The groundbreaking module could last longer and generate more power than the conventional variety. The team’s new bifacial solar module could offer better, more efficient solar energy in the near future. It can absorb light on both its front and back sides. Their prototype was made with bifacial ZEBRA IBC solar cells, which have an efficiency of up to 22 percent. According to SERIS CEO Armin Aberle, these IBC cells are known for reliability and durability. Related: New bifacial solar module takes advantage of direct and reflected sunlight Double- glass insulation enclosing the module means its warranty could be longer than most solar modules: 30 years or even more. And since the cells are bifacial – the researchers report a bifaciality of 75 percent – the module can produce up to 30 percent more power . SERIS’ PV Module Cluster Director Wang Yan said, “With SERIS’ new module design, panels with 350 watts front-side power can be made with 60 23 percent efficient screen-printed IBC cells. Considering an additional 20 percent of power via the panel’s transparent rear surface, each 60-cell IBC bifacial module will produce a stunning 400 watts of power in the real world.” The revolutionary solar module will be displayed at the upcoming International Photovoltaic Power Generation Conference & Exhibition from April 19 to 21 in Shanghai, China. Aberle said, “The module technology offers world-class front side power while providing free extra power from the rear side.” He said the next step is transferring the technology to industrial partners, and the product could be on the market in around two years.

This carved wood bench hides an unexpected surprise

Comments Off on This carved wood bench hides an unexpected surprise

This simple-looking bench hides a two-fold surprise. A closer look reveals that the ‘tufted’ bench is actually carved out of solid wood – and when you sit down it’s bouncy and soft! Valentijn Rieb and Andrea Schimmer perfectly replicated the iconic form of a Chesterfield bench while marrying the look of wood with the comfot of a springy seat. Chester-Block-Hocker updates the classic Chesterfield bench with carved beach wood blocks. The soft, bouncy element comes from the inner support structure of the bench. Thanks to springs located under each diamond-shaped chunk of wood, this bench serves as a cushy seat. The legs of the bench are upholstered with leather to make the transformation complete. Related: Max Lamb’s “Exercises in Seating” is a primitive investigation of materials at Milan Design Week This design is the result of modern technology meeting manual labor and traditional craftsmanship. To realize Chester-Block-Hocker, the blocks were CNC milled and shaped by hand. Made with the utmost precision and a great attention to the detail, this bench offers a soft touch and a surprising material experience that will intrigue you each time you take a seat. The Chester-Block-Hocker won the Baars & Bloemhoff “Master of Materials” prize and is on show at the Masterly Dutch exhibition at Palazzo Turati in the 5VIE design district at Milan Design Week 2017 . + Milan Design Week images by Maria Novozhilova for Inhabitat
