U.K. Facility Adds Ability to Test Sun Exposure
The U.K.’s Millbrook vehicle test and development center has expanded its ability to duplicate the effect of the sun on vehicles and components through an entire day cycle, notes The Engineer Online.
Millbrook says its Variable Temperature Emissions Chamber can operate over a range of -40°C to +50°C. It new six-panel solar array can generate irradiance of more than 1,400 watts per square meter.
Tesla Plans “Low-Cost” EV by 2015
Tesla Motors Ltd. plans to debut a relatively inexpensive €21,400 electric car in six years that will be about the size of a BMW 3 Series sedan and sell in volumes of more than 150,000 per year, reports Autocar.
Tesla introduced its first EV, the Lotus-based Roadster, two years ago at a price of €71,600. It has sold 1,000 of the cars so far. Its next vehicle, the Model S sedan, debuts next year at €38,500. Coupe and crossover variants are expected to follow and help annual sales of the S to reach 30,000-50,000.
The third model, which has not yet been named, also will include other body styles in addition to a sedan. Tesla intends to build those cars and the Model S at a plant in California.
Think to Test Quick-Charge System for EV Batteries
Think Global AS says it is partnering with California-based AeroVironment Inc. to demonstrate an EV recharging system that can bring a fully depleted Th!nk City EV battery back to 80% capacity in 15 minutes.
The project was announced this week at the Washington auto show. Think said earlier in January it will open a U.S. manufacturing plant in Indiana next year that can build as many as 20,000 Th!nk City cars annually.
AeroVironment has previously developed quick-charge system for the U.S. military. The company also was chosen earlier this month by Nissan North America to supply home recharging systems and installation services to support the carmaker’s Leaf EV, which goes on sale in the U.S. later this year. AeroVironment’s recharging system for Nissan is expected to take about 26 minutes to achieve 80% power.
Study to Assess Impact of Climate Change on Traffic
The EU has begun a three-year research project to determine the impact on traffic systems of severe weather caused by climate change. The €2 million study will be coordinated by the VTT Technical Research Center of Finland.
VTT says the project was prompted by concern about the increase in cases of extreme weather caused by global warming. It will assess the cost of resulting disruptions in terms of damage, disrupted supply chains and human casualties.
The research center says the primary goal is to help Europe adapt to the likelihood of increasingly disruptive weather by assessing infrastructure, enhancing cooperation among authorities responsible for preparedness and “pre-engineering” risk management techniques. VTT notes that its findings may be useful to insurance, financial and business planners.
Researchers May Test Space-Based Solar Power Delivery System
Engineers at Astrium, the Paris-based space systems subsidiary of EADS, say the time is right to develop a system that gathers solar energy in space and delivers it back to Earth through a laser beam. They hope to launch a demonstration system within five years that can collect and beam as much as 20kilowatts to the ground.
The researchers say the surge in interest in electric vehicles makes the scheme especially appealing now. They point out that solar collectors in orbit around the Earth would be exposed to stronger solar radiation and for longer periods than is possible with solar panels on the ground.
The idea of collecting solar power in space and beaming it to Earth isn’t new. But Astrium says the technology to do so is now viable. They envision a system that collects solar energy and uses it to power a laser aimed at a mirrored collection point on the ground. They concede the higher cost of a space-based system and the relative inefficiency of converting the energy to a laser beam. But they contend that those factors would be offset by the system’s ability to operate for a much higher proportion of a 24-hour day—including delivering power at night.
