This hoverboard costs $20,000 and can fly for six minutes

Posted by in categories: energy, space, transportation

2015 was literally and figuratively the year of the hoverboard. While everyone was talking about the self-balancing scooters, two companies showed off skateboard-shaped boards that actually hovered a few inches above the Earth: Lexus with the “Slide” board, and Arx Pax with its second generation Hendo Hoverboard. Now, just days before the new year, another company called ArcaSpace is taking a shot at making the mythical hoverboard.

ArcaSpace is primarily a private space company, and one of the original 26 teams that competed in the Ansari X Prize competition in 2004. (It also entered the Lunar X Prize competition, too, before pulling out in 2013.) But early this morning the company released a video that shows off the “ArcaBoard,” a fan-powered rectangle that can lift a person off the ground by almost a foot.

The ArcaBoard gets its power — 430 pounds of thrust, or 272 horsepower, according to the company — from 36 electric fans. The company also says its built in some self-balancing tech to make it fly smoothly. Beyond that, though, it doesn’t look like there’s much to the experience. Dumitru Propescu, ArcaSpace’s CEO, is seen riding it in the video, but it doesn’t look like he has much control over where it’s going. It’s actually pretty reminiscent of the Hendo Hoverboard videos — sure, it hovers, but you can’t really steer it enough to ever use it to get anywhere.

China wants to begin manned deep space missions

Posted by in categories: economics, energy, engineering, materials, neuroscience, robotics/AI, space

China wants to be the leading force in manned space exploration, and is exploring sending people to the far side of the moon, Mars, asteroids, and further into deep space.

Becoming the second largest economy in the world and an emerging superpower of its own, China wishes to add deep space exploration into its achievement portfolio. Besides the ongoing moon exploration, its scientists are considering going deeper into the solar system, including Mars, asteroids, and even manned deep-space mission. Liu Jizhong, director of the lunar exploration program and space engineering center, pointed out that China has to be more pioneering, tackling problems such as high speed deep space exploration, energy and power generation, space robot development, and more. He also said that China must cooperate with others as space exploration is an undertaking shared by the entire human species.

China currently intends to explore the far side of the moon, something that has never been done before. It would require a relay satellite for communication and navigation on Lagrange point, where the satellite could orbit within the combined gravitational pull of the Earth-moon system, as said by Zhang Lihua of China Spacesat Co. While China believes that robots are critical to the mission, it also believes that these trips must be manned in order to effectively leverage human decision-making. China also says they are designing footed robots to explore asteroids and better understand their material composition.

Sony plans to boost battery performance 40 percent

Posted by in category: energy

Sony is planning to commercialize lithium-sulfur batteries by 2020, and promising increases of up to 40% over conventional lithium-ion architectures. The devil is in the details, but a battery with 40% more specific energy at the same weight and cost as lithium-ion would enable EVs at lower price points.

Coal miners mine coal; diamond miners mine diamonds; gold miners mine gold; space miners (will) mine space—and anything in it that has precious metals or compounds that can be whisked into rocket fuel. But, just like the first three kinds of “resource extraction,” the celestial kind will face more than a few philosophical, financial, and regulatory complications.
