"2005 Stanford Solar Car Project members with their car, Solstice The Stanford Solar Car Project (SSCP) is a student group at Stanford University that designs, builds, tests, and races solar-powered vehicles. The SSCP, a student- run, donation-funded organization, has been building and racing solar-powered vehicles since 1986. It has competed and placed at The World Solar Challenge, the Global Green Challenge, and American Solar Challenge. The Stanford Solar Car Project has historically prided itself on being a completely student-run project. There is no faculty involvement at a managerial or technical level; faculty involvement is limited to advocacy and fundraising. The project is open to Stanford students in all fields of study and seeks to educate groups on and off campus about applied engineering and renewable energy. The project works at the Volkswagen Automotive Innovation Lab, a building shared with the Stanford DARPA Grand Challenge team, the Dynamic Design Lab, and other automotive research groups. However, work on the car continues at all times during the week, especially in the weeks and months leading up to a race. Past cars The Stanford Solar Car Project has a long history of designing and racing innovative solar-powered race cars. Past cars include SUnSUrfer, SUnBurner, AfterBurner, AfterBurner II, Third Degree Burner, BackBurner (an alumni project), Back 2 Back Burner, Solstice, Equinox, Apogee, Xenith, Luminos, and Arctan. Apogee The team's ninth car, Apogee, placed 4th in its class and 10th overall at the 2009 Global Green Challenge in Australia, 4th overall in the 2010 American Solar Challenge, and 10th in its class at the World Solar Challenge 2009. Xenith Xenith during a test drive in the San Joaquin Valley Xenith, the team's tenth car, was unveiled on August 11, 2011 and placed 11th at the World Solar Challenge 2011. Xenith is a 375-pound vehicle that is powered entirely by the sun. Xenith features a three-wheel steering system, glass encapsulated solar panels, and a high-efficiency electric motor. It has a 4-inch thin chassis made of carbon fiber composites, titanium, and aluminum. The vehicle's two front wheels are controlled by a normal rack and pinion steering wheel, and the rear wheel is controlled by a linear actuator.http://news.stanford.edu/news/2011/august/xenith-solar- car-081011.html The vehicle can travel at 55-60 mph under sun power alone, and it can reach higher speeds when using the reserve battery pack. The vehicle is the first solar-powered car to use flexible glass for panel encapsulation. The ultra-high-efficiency silicon panels use prototype glass from Corning and cells from SunPower. The team used a custom 98% efficient motor for the vehicle. An in house developed software program allows the team to model sunlight and shadows during the race in order to plan race strategies. Luminos Luminos placed 4th at the 2013 World Solar Challenge. Luminos, the team's eleventh car, was unveiled in the summer of 2013. It placed 4th in the Challenger class of the World Solar Challenge 2013, the best finish by an undergraduate team. Luminos was the team's most successful vehicle to date, proving sturdy and reliable with 10,000 safe miles successfully logged. Arctan Arctan, the team's twelfth car, was unveiled in July 2015. It placed 6th in the Challenger class at the 2015 World Solar Challenge. Arctan was built with the intention of being a slightly more aggressive improvement on the 2013 car, with a more aerodynamically efficient design without compromising on robustness. Arctan logged even more safe test drive miles than Luminos before it and finished the race 50% closer to the top team than in 2013. Sundae Sundae, the team's thirteenth car, was unveiled in July 2017. It placed 9th in the Challenger class at the 2017 World Solar Challenge out of 12 teams. The car was significantly smaller, being built in accordance with the new rules for the 2017 World Solar Challenge, which only allowed for four square meters of silicon solar cells. There were more aggressive aerobody optimizations applied compared to what had been done in the past.

"The Round House is a cylindrical, wood-frame residential building at 36 Atherton Street in the Spring Hill neighborhood of Somerville, Massachusetts, United States. It was built in 1856 by hardware manufacturer Enoch Robinson, and is considered an offshoot of the octagon house-style popularized by phrenologist Orson Fowler. The exterior of the Round House features two flush stories, with a third stepped back behind a series of battlements and embrasures. Inside, the three-story structure contains a central rotunda topped with a glass skylight, with interconnected rooms branching off on each level. There are four rooms on the first floor, six rooms on the second floor and another four rooms on the third floor. History In the early 2000s, the privately owned house was unoccupied, its windows removed to the interior of the house, and the openings were covered with plywood. Its ornamentation was largely removed, and all of the ceilings were severely damaged from water. In a 1986 restoration program, students from Boston's North Bennet Street School did a small amount of work renovating the exterior, but the project fell apart and the house remained in a state of decay. Historic Massachusetts (now Preservation MASS) placed the building on its list of Endangered Historic Resources for 1997. The Round House in 2008 as renovation begins The Round House in 2015 seen facing east towards Boston Postcard from 1913 showing Robinson Round House By April, 2007, the Round House had been purchased by a local man who is also president of a general contracting firm. Signs placed on the property in early January 2008 advertised nearby Diamond Edge Construction, and the thick brush filling the yard was largely removed. According to a letterhttp://community.livejournal.com/davis_square/736223.html?thread=5901535#t5901535 from Brandon Wilson, executive director of the Somerville Historic Preservation Commission, the building and property would be completely restored and would function as a single family residence when complete.
