The Car That Runs On Air

For more than a century, air cars have remained as a very large controversy for engineers and an idealistic exercise with little likelihood of entering mass production. As fuels goes, air has a many upsides to it: It’s found every where, clean, and, best of all, it's free. But air requires energy to store energy because it must be compressed, limiting the use of an all-air car. Two engineers from French automaker PSA Peugeot Citroen thought they could overcome that problem by pairing a gasoline engine and hydraulics. To test the concept, they formed the Hybrid Air Program in 2010 and connected the engine of a subcompact car to a commercial airplane’s hydraulic system. During normal driving, the system will switch between gas and air power, says Yarce. Much like with hybrid-electric vehicles, the gasoline engine provides a boost up steep hills and on the highway, and it re-pressurizes the nitrogen tank if the regenerative-braking system hasn't done so. The prototype was so successful that PSA has decided to manufacture and sell the production vehicles.The Hybrid Air power-train will appear in all subcompacts as an option in Europe and possibly other international markets in 2016.

Web 2.0: Multimedia Blog Posting Sem 2

       

       In my first semester Intro to Art class, my teacher was Ms. Hemmel. I expected to learn more about the types of tools to use for Art and how to use them correctly. We have learned many different things this year including how to use plaster for masks and the era from which the type of mask came from. We were even able to work with clay. The class Is almost a free period for me because this is the only subject i'm interested in and good at, besides Web 2.0.

       I have had Art class every year so far since I have been here, so doing something different like the masks was very interesting. She grades us very strict and fair with big projects and weekly 45 minute observational drawings. We even watched some video that taught us on how to use a picture plane view finder. The picture had some slow moving and boring old woman but it was one of the funny memorable moments of taking that class.

      "It was a semester long course designed to introduce students to the disciplines of art: art production, aesthetics, art history, and criticism with an emphasis on the elements of art". The only time we used technology in the class was when we used the Mac computers in her room. I liked doing the projects because you were able to take the assignment home with you. Ms Hemmel is a very nice teacher which is why Art is one of my favorite classes.

Connecticut Fire Department Gets Help From A Drone

Tech Article 2/7/2014

• When a fire broke out near a storage unit full of explosives, an RC quad-copter saw what humans couldn't.
• Last week, hundreds of people were evacuated from the area surrounding the pink granite Stone Creek Quarry in Connecticut when old blast mats--heavy rubber sheets placed over holes to contain explosions--caught fire.
• Emergency workers were concerned that the fire was getting close to a storage unit containing dynamite and other blasting explosives, making it too dangerous for firefighters to go in.
• The drone is expensive from a toy perspective, but at $1,200, it's a cheap alternative to helicopter flights.
• Besides cost, there are two major advantages for firefighters using drones: small unmanned aircraft can see places people can't, and they can fly into situations that are too dangerous for humans.
