Rome (Italy), Feb 10 (EFE), (Camera: Paula Bernabé).- Some works to expand the basements of the Spanish School of History and Archeology in Rome have brought to light the remains of a wall from the 4th century BC. FOOTAGE OF THE WALL AT THE SPANISH SCHOOL OF HISTORY AND ARCHEOLOGY IN ROME.
Developing alternative powertrain technologies is a top priority for the BMW Group. The premium carmaker offers first virtual insights into the powertrain system for the BMW i Hydrogen NEXT and reaffirms its commitment to following a carefully considered and systematic route to emission-free mobility. This approach also includes the careful consideration of differing market and customer requirements as part of the company’s Power of Choice strategy. Customer centricity and the flexibility needed for this are essential in facilitating the breakthrough for sustainable mobility on the global stage.
This array of 149 Xenon short-arc lamps is called Synlight, and it's designed to be an artificial sun. Invented by the German Aerospace Centre, or DLR, Synlight can produce up to 10,000 times the intensity of natural sunlight experienced on Earth. Researchers and scientists turned on their machine for Ruptly in Juelich on Monday. The Synlight array measures 45 by 52 feet but all the powerful bulbs are designed to concentrate their light radiation on a small space which measures just 8 inches by 8 inches. Its inventors claim that the synthetic sun can generated temperatures up to 3000 degrees Celsius and beyond. Synlight was created with a specific purpose in mind. Hydrogen fuel, considered by many to be the fuel of the future because it emits no carbon when burned, is derived by breaking water down into its base atoms. However, this process requires a huge amount of heat energy. Synlight is meant to power the reaction to obtain hyrdogen fuel in a way that uses as little fossil fuels as possible. The high power array also has potential uses in other fields as well, including scientific research and commercial applications which require an intense source of heat. The project cost about 3.5 million euro to buid, funding which was provided by the German government and automaker BMW.
Buzz Aldrin: A New "Race for Space" Dr. Buzz Aldrin, the second human to walk on the moon, is a leading advocate of space science and planetary exploration. He is the co-author of several books, including "Mission to Mars: My Vision for Space Exploration" and "No Dream Is Too High: Life Lessons From a Man Who Walked on the Moon." He lives in Satellite Beach, Florida. Given President-Elect Trump's interest in putting in place a space council, I envision a more unified approach to shaping and overhauling aspects of America's civil, military, and industrial space sectors. And get ready for intense competition in the development of human spaceflight systems, not only for use in low Earth orbit but also outward from our home planet. This commercial "race for space" will lead to technical and business innovations we don't yet appreciate or understand. I think the year ahead will see Jeff Bezos's Blue Origin group wring out its New Shepard reusable suborbital launch vehicle and press forward on its New Glenn booster. Similarly, Richard Branson's Virgin Galactic SpaceShipTwo will hasten the pace of testing to create suborbital passenger service. And keep an eye on the maiden flights of the Boeing CST-100 Starliner and the SpaceX Dragon 2 capsules — stepping stones to restore our nation's capabilities for human spaceflight. I expect Elon Musk and his SpaceX rocketeers will fly their Falcon Heavy launcher from the refurbished Launch Complex 39 pad A at the Kennedy Space Center in Florida. That's the same site that I rocketed from with my Apollo 11 colleagues, Neil Armstrong and Michael Collins, to achieve the first human landing on the Moon in July 1969! China is headed for several milestone achievements. For one, they will use their new Long March 5 and Long March 7 boosters to advance their goal of building their own space station. In addition, look for China to fly to the moon the robotic Chang'e 5 spacecraft and attempt the first lunar sample return to Earth in more than 40 years. Lastly, look for surprises from mysterious Mars! Now orbiting the Red Planet is the European Space Agency's ExoMars Trace Gas Orbiter that in 2017 will "sniff out" whether methane detected on that world is a product of Martian microbes. Personally, I'll be working as hard as ever to rally public and political willpower to hasten the day when those first footfalls on the Red Planet lead to permanent inhabitation of Mars.
Republican presidential candidate Donald Trump stressed his intention of building a wall along the southern border of the USA and Mexico, as part of his 10 point plan for tackling illegal immigration, during a rally Roberts Centre in Wilmington, Ohio on Thursday.
