Comments Off on Mercedes takes on the Tesla Powerwall with a new battery for buildings

Tesla’s Powerwall has reigned supreme in home energy storage , but now they’ve got some competition from Mercedes-Benz . Last year, Daimler , parent company of Mercedes-Benz, announced that they had started developing their own brand of home energy storage units. Now the company confirmed they are beginning to deliver the units to businesses and homes in Germany . Mercedes incorporated the same lithium-ion battery technology from their hybrid cars in the new home energy storage units. Each unit has an energy content of 2.5 kilowatt-hours (kWh), and a system can be scaled up to include eight modules for a total of 20 kWh. The units come with a 10-year warranty , the same as the Tesla Powerwall , though Powerwalls come with the option to store more energy with a capacity of 13.5 kWh. Related: BMW, Daimler, Ford, and VW are planning an electric vehicle superhighway in Europe Similar to a Powerwall, Mercedes’ battery storage units store excess energy gathered by solar panels for use during peak hours or at night. According to Daimler , homeowners using their system can increase renewable energy use by as much as 65 percent. Daimler aims to expand throughout Europe and start selling the units in the United States this year. Mercedes is already developing three industrial-scale projects to provide reliability to the grid in Germany; one project includes 29 megawatt-hours of storage capacity. Mercedes is also offering a package for homeowners that comes with the battery storage unit, solar panels, an inverter, and an energy management system. The whole package, including installation, costs around $10,000. One 14 kWh Tesla Powerwall costs $5,500 ; with supporting hardware the total estimate is $6,200. Installation costs between $800 and $2,000. That doesn’t include a solar power system. Head of Development Electrics/Electronics and E-Drive for Mercedes-Benz Harald Kröger said in a statement, “We are convinced we can offer our customers an attractive product at a competitive price.” Via Treehugger Images via Mercedes-Benz and Daimler

Comments Off on Tesla’s Gigafactory to be the largest building on Earth?

Tesla is constructing a building completely powered by renewable energy that can hold enough battery power for 500,000 Tesla cars . And it’s going to be huge. It’s quite possible that calling it the Gigafactory is more literal than we initially thought. Read the rest of Tesla’s Gigafactory to be the largest building on Earth?

Comments Off on Falling price of battery packs may usher in age of affordable electric cars

A new study from the  Stockholm Environment Institute has found that the price of lithium ion (Li-ion) battery packs has been falling far faster than previously reported , with the price per kWh dropping by a whopping 70 percent since 2007. It’s a surprising statistic—previous studies anticipated we would not see these prices until 2020—and points to a trend that could lead to electric cars becoming cost-competitive with regular gasoline-fueled cars within the next decade.

Comments Off on Perspiration to perfume: New fragrance smells better when you sweat

What if perspiration actually made us smell better? Thanks to researchers at Queen’s University Belfast , that possibility has arrived. They’ve created a new fragrance delivery system that releases more aroma when it comes in contact with moisture – so you’ll essentially smell better the more you sweat.
