Wind power on Mars makes it possible for any rover or other craft to collect power at the poles or other areas on the planet that don’t get constant sunlight.

Dashing around a battlefield in the bulky robo-armor Tom Cruise wore in Edge of Tomorrow won’t cut it in the real world. For starters, it’s way too big. And the energy required to power something that size—via a gas engine strapped to your back in some early inventor iterations—is noisy and a giveaway to the enemy that you’re approaching.
But a raft of newly developed exoskeletons is starting to meet the slimmed-down, stealth requirements of today’s troop commanders, who see these power-assisting suits as vital to the future combat missions. Among the most promising, and weird-looking, is the “third arm” that the U.S. Army Research Laboratory developed to help soldiers carry and support their weapons on the battlefield. The lightweight device, which weighs less than four pounds and hangs at a soldier’s side, stabilizes rifles and machine guns, which can weigh up to 27 pounds. This improves shooting accuracy and also minimizes fatigue. It can even be used while scrambling into position on the ground.
The kind of fatigue that the third arm aims to negate is a killer on the battlefield, and most of the new suits are similarly meant to help troops minimize the energy they use to carry enormous supply packs, weapons and other battlefield gear. In May, Lockheed Martin unveiled its lightest weight powered exo for lower body support. Dubbed ONYX, the form-fitting suit, which resembles an unobtrusive web of athletic braces, reduce the effort soldier’s need for walking, running, and climbing over varied terrain while carrying a heavy loads of up to 100 pounds.

Covering roofs and walls of buildings with vegetation is a good way of reducing greenhouse gas emissions. And these green roofs and walls make cities look nicer. Toronto’s central business district adopted a policy of establishing green roofs on around half of all city buildings in 2009. Research shows this could reduce maximum city temperatures by up to 5℃.
We spent the past 12 months analysing the case for more greenery on Australian city buildings, drawing on international comparisons. We’ve shown that a mandatory policy, coupled with incentives to encourage new and retrofitted green roofs and walls, will provide environmental, social and business benefits.
These include improved air quality, energy conservation and reductions in stormwater run-off from buildings, which would decrease flash flooding. Green roofs and walls also become new habitats for biodiversity and can be pleasant spaces for social interaction in dense urban areas.

Renewable resources are great, but they bring a new element of uncertainty to a power grid. This element can lead to failure in surprising ways, according to a new paper.
A team of researchers built a model of power grids that transport electricity from solar and wind power. That means that there are places where the grid receives fluctuating inputs of power, since levels of sunlight and wind and vary.

Now Mr. Liu is promoting UHV internationally through his Global Energy Interconnection initiative. Designated a “national strategy” and championed by Xi Jinping, China’s president, the initiative feeds into one of China’s most ambitious international plans — to create the world’s first global electricity grid.
China’s dream of building a global electricity grid may be coming true, the Financial Times reports.

A contentious proposal to link oversight of California’s electric grid with other western states faces a crucial test Tuesday in a state Senate committee.
Supporters say regionalizing the grid would make it easier and cheaper to deploy renewable energy across the western United States. But critics, including some environmentalists and consumer advocates, say California would jeopardize its efforts to require the expansion of renewables.
California has greatly expanded the use of renewable energy sources, particularly wind and solar, but that’s brought new challenges for grid operators to manage supply and demand as weather patterns and sunlight vary.

One night, as I was putting my daughter to bed and waiting for her to fall asleep, I tried to think of some new markets for space utilization.
We often hear about attempts to find industrial uses for microgravity for growing crystals, for purification of electronic materials (which is an actual thing with ACME Advanced Materials: http://www.a2-m.com/), maybe growth of certain metal foams, etc. However, in space, you’re in both a hard vacuum and not physically resting on anything, so you can spin up something, and it will simply keep on spinning (stably, if you spin it around the correct axis) nearly indefinitely without any additional energy input and no wear on bearings or anything. So in fact, you can get basically any gravity level you want, including HYPERgravity, nearly for free.
What are the applications of this?

SpinLaunch Inc. has closed a $35 million Series A funding round with a powerhouse syndicate of investors. Investors include Airbus Ventures, GV (formerly Google Ventures), and Kleiner Perkins. This syndicate joins institutional investors including Lauder Partners, ATW Partners, Bolt, and Starlight Ventures to total $40 million. Investment funds will be used to scale the team and technology, through first launch by 2022.
SpinLaunch is revolutionizing access to space by developing a kinetic energy launch system designed to provide the world’s lowest-cost orbital launch service for the rapidly growing small satellite industry. Their environmentally responsible approach is unmatched in the industry. SpinLaunch is currently considering four different states for potential launch sites within the United States.
Spinlaunch use large centrifuges to store energy and will then rapidly transfer that momentum into a catapult to send a payload to space at up to 4,800 kilometers per hour (3,000 mph). If successful, the acceleration architecture is projected to be both lower cost and use much less power, with the price of a single space launch reduced to under US$500,000.
