Space is not a government program; it’s the rest of the Universe. Private space business is now a major factor, bent on finding investors interested in generating profits by making space more accessible to more people. Space business pays taxes to governments; it does not consume tax revenues. Further, space business can offer launch services to government agencies at highly competitive rates, thus saving taxpayer dollars. How can they do this, competing with government-funded boosters with a 50-year track record? Simple: governments have no incentive to cut costs. Traditional aerospace industry giants have a huge vested interest in boosters that were developed to military and NASA standards, among which economy was not even an issue. But innovative, competitive companies such as XCOR Aerospace and Mojave Aerospace, without such baggage (and overhead) can drive costs down dramatically. This is a proven principle: notice that we are no longer buying IBM PCs with 64 k of RAM for $5000 a unit.

Even more important in the long view, space is a literally astronomical reservoir of material and energy resources. The profit potential of even a single such resource, such as solar power collectors in space beaming microwave power to Earth, is in the trillions of dollars. What would it be worth to the world to reduce fossil fuel consumption by a factor of 20 or 100 while lowering energy costs? Can we afford to continue pretending that Earth is a closed system, doomed to eke out finite resources into a cold, dark future?

Can we afford space? Wrong question. Can businesses afford space? Yes. We get to reap the benefits of their innovative ideas and free competition without footing the bill.

Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun’s energy and then releases it as a burst of heat to melt away a layer of ice.

According to a team of researchers at MIT, both scenarios may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat, whenever it’s needed. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.

Although the sun is a virtually inexhaustible source of energy, it’s only available about half the time we need it—during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat.

Governments, businesses, and economists have all been caught off guard by the geopolitical shifts that happened with the crash of oil prices and the slowdown of China’s economy. Most believe that the price of oil will recover and that China will continue its rise. They are mistaken. Instead of worrying about the rise of China, we need to fear its fall; and while oil prices may oscillate over the next four or five years, the fossil-fuel industry is headed the way of the dinosaur. The global balance of power will shift as a result.

LED light bulbs, improved heating and cooling systems, and software systems in automobiles have gradually been increasing fuel efficiency over the past decades. But the big shock to the energy industry came with fracking, a new set of techniques and technologies for extracting more hydrocarbons from the ground. Though there are concerns about environmental damage, these increased the outputs of oil and gas, caused the usurpation of old-line coal-fired power plants, and dramatically reduced America’s dependence on foreign oil.

Catching sunlight at every angle.

One of the limitations of current solar panel technology is the panels need to be facing in a certain direction to make the most of the Sun’s rays, otherwise the amount of energy they can absorb drops off dramatically. A newly invented material could make the direction of solar panels much less of a concern in the future.

The material has been produced by electrical engineers at the King Abdullah University of Science & Technology (KAUST) in Saudi Arabia and Taiwan’s National Central University. Not only does the glass coating they’ve come up with soak up sunlight from multiple angles more effectively, it’s also able to keep itself clean — the newly treated panels were able to maintain 98.8 percent of their efficiency after six weeks outdoors.

In the third century BCE, King Hiero II of Syracuse asked Archimedes to devise a number of death traps to thwart Roman invaders. Among the many designs the great inventor drew up was a solar death ray. The basic idea was to build an array of mirrors that could reflect rays of light into a central blast, causing Roman ships to burst into flame. It’s unlikely the weapon ever made it past the blueprint stage, but it became an incredibly influential model nonetheless. Archimedes was perhaps the first solar power convert, searching for a way to take advantage of the inconceivable amount of energy our friendly neighborhood star barfs up every second.

The only thing that would make Archimedes’ solar death ray more fascinating is if it was technically feasible, socially benevolent, and in space. That’s where John Mankins comes in. A NASA veteran, aerospace entrepreneur, and space-based solar power (SBSP) expert, Mankins designed the world’s first practical orbital solar plant. It’s called the Solar Power Satellite via Arbitrarily Large PHased Array, or SPS-ALPHA for short. If all goes to plan, it could be launched as early as 2025, which is sooner than it sounds when it comes to space-based solar power timelines.

Scientists have been aware of the edge the “space-down” approach holds over terrestrial panels for decades. An orbiting plant would be unaffected by weather, atmospheric filtering of light, and the sun’s inconvenient habit of setting every evening. SBSP also has the potential to dramatically increase the availability of renewable energy.

An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors. Their downside? The films are notoriously riddled with defects, killing their performance.
