3-D Printing in Space

The International Space Station has received its first 3-D Printer on 23 september 2014. NASA successfully tested the 3-d printing machine and it could operate in microgravity. It will give a cutting edge to scientists in ISS to manufacture it on board.A 3-d printer works by building the layer of materials like platics, metals in powered form by heating it. It is one of the greatest technological leap for mankind to produce items in space.

A new future weightless Insulation material

A totally new insulation material has been developed that is totally weightless but can still withstand high temperature, that would not be tolerated by other materials and destroy it. The porous aerogel is at least 99 percent open space , with the rest made up of an atomically thin ceramic called hexagonal boron nitride. The design proves extremely durable under high temperatures and rapid temperature shifts of over 1,000 degrees Celsius. “It’s notoriously hard to make materials that are not just lightweight, but can also be heavily heat resistant,” says Deep Jariwala, an engineer at the University of Pennsylvania. The new ultralight insulator may be especially well suited to shielding components on spacecraft , which must endure extreme temperature swings when turning toward or away from the sun or re-entering Earth’s atmosphere, he says. The aerogel comprises a network of tiny air pockets, with each pocket separated by two atomically thin layers ...

Top 3 Fastest Hydrogen Powered Car

When it comes to racing using hydrogen powered car, this top three car will win the show. Hydrogen powered car uses hydrogen gas as a fuel which combust with oxygen to form water. #3. Aston Martin Rapide : British luxury marque ASTON MARTIN introduced AM Rapide S in early 2010. The Rapide is powered by a 5,935 cc V12 engine , producing 470 bhp and torque of 443 lbf·ft (601 N·m). It is Rear-wheel drive and has a six- speed Touchtronic automatic. The Rapide can reach a top speed of 188.5 mph (303 km/h), and accelerate 0-100 km/h (62 mph) in 5.3 seconds, or 0-60 mph (97 km/h) in 5.0 seconds. #2. BMW H2R : This car built by BMW uses liquid hydrogen as a fuel. The H2R’s 6.0-liter V-12 engine, which draws on BMW 's Valvetronic and Double-Vanos technology, is based on the 760i’s gasoline-fueled powerplant. This H2-powered high performer generates 232 horsepower (173 kW), helping it t...

Compact Fusion Reactor in the size of a truck

Think about a truck supplying the energy demand of a whole city. Well it seems to be the thing of the future and definitely of not this century. But Lockheed Martin is working on building a truck size nuclear fusion reactor that will ready before next 10 years. The reactor which will be small enough to fit on the truck will be able to power the city of 100,000 people.It will revolutionize the Earth energy requirement and production. The reactor will fuse two hydrogen atoms into a single helium atoms, releasing a energy ten times than the regular nuclear reactor. Fusion will offer a cleaner, safer source of energy. It will use a "magnetic bottle" to contain the hundreds of million of degreed created by the nuclear fusion reactor. It will be useful in spacecraft to mars, and power generation in aircraft carrier and large ship, and also in puring large quantites of water. It can provide plane will unlimited range.
