REDSTONE ARSENAL, Ala. — The U.S. Army Space and Missile Defense Command/Army Forces Strategic Command announced the successful completion of the Factory Acceptance Test for the 60kW Spectrally Combined High Power Solid State Fiber Laser program March 16.

During the testing conducted last week, the laser demonstrated a sustained power of 57.5kW for a duration of 200 seconds with good beam quality. This level exceeds the contract threshold for success, and with the addition of three more channels planned before delivery, power will exceed the 60kW program objective.

This important technical milestone represents the first successful demonstration of a high power fiber laser at this power level for defense applications. After delivery, the laser will be integrated with the High Energy Laser Mobile Test Truck where it will be used in test environments to support analyses and studies related to warfighting applications.

CAMBRIDGE, Mass. — A new propulsion engine with dime-size thrusters could be used to propel a host of spacecraft, from small satellites to crewed ships designed for interplanetary exploration.

The new propulsion engine, called Tile, could serve as an efficient and lightweight way to keep constellations of small satellites in orbit. Spaceflight companies — including OneWeb, Boeing and SpaceX — want to launch hundreds of thousands of these small satellites to provide broadband internet to everyone around the globe. And because several Tiles can be connected to produce more power, the engine has the potential to propel astronauts to Mars, according to Accion Systems, the company that designed Tile.

“Our technology starts on a nanometer scale, and then we can array that and scale that up to serve satellites,” said Natalya Bailey, CEO of Accion Systems. Bailey described the propulsion engine to an audience here at the New Space Age Conference at the Massachusetts Institute of Technology’s (MIT) Sloan School of Management on March 11.

Beijing: The closure of Beijing’s last big coal-fired power station, which had dominated the skyline of the city’s outskirts for 18 years, has been welcomed by environmental groups, who hope China will maintain momentum on its ambitious clean energy targets.

Beijing had promised in 2013 to have its four coal-fired power stations shut down by this year.

The World Economic Forum has posted an article that hints at something that I have also suggested. (I am not taking credit. Others have suggested the idea too…But advancing tech and credible, continued visibility may help us to finally be taken seriously!)

I am not referring to purchasing and retiring carbon credits. I like that idea too. But here is a blockchain idea that can enable fleets of autonomous, shared, electric vehicles. Benefits to individuals and to society are numerous.

The future is just around the corner. Non-coin applications of the blockchain will support many great things. Goodbye car ownership. Hello clean air! The future of personal transportation.

Read about it at the World Economic Forum.
