Bionic Power makes wearable technology for charging batteries. Today, we are focused on developing our PowerWalk® Kinetic Energy Harvester for military use and will begin multi-unit field trials with the U.S. Army and U.S. Marine Corps next year. In the future, we see our walk-recharge technology being used in disaster zones and remote worksites, and by consumers in recreational, emergency preparedness and backup applications.
Ubiquitous, mobile supercomputing. Artificially-intelligent robots. Self-driving cars. Neuro-technological brain enhancements. Genetic editing. The evidence of dramatic change is all around us and it’s happening at exponential speed.
Previous industrial revolutions liberated humankind from animal power, made mass production possible and brought digital capabilities to billions of people. This Fourth Industrial Revolution is, however, fundamentally different. It is characterized by a range of new technologies that are fusing the physical, digital and biological worlds, impacting all disciplines, economies and industries, and even challenging ideas about what it means to be human.
Say this for DARPA, it’s not shy about picking ominous names for its projects. Or, in this case, not worried when the partners it works with choose them. Pictured above: the “Nightmare” a “stealth bike” developed by LSA Autonomy for DARPA that has just been moved on to the second stage of development, according to Defense One. DARPA commissioned both it and another bike from Logos Technologies to meet some specific goals: run quietly on electric power, but also run on whatever fuel a soldier in the field.
Alex Dzwill of Logos told Defense One that its bike, the SilentHawk, could run on anything from gasoline to propane to jet fuel:” It will figure it out.”
Interesting…
First, we take ‘Time’, as we know it’s one of those things that we take for granted—time moves forward and never backward. But did you ever stop to wonder why it moves in one direction, as opposed to the other?
The question continues to stump physicists. After all, there are certain physical processes that are actually time-reversible—they look the same no matter which way you run them.
For example, gravity operates the same way regardless of Time’s Arrow; a planet will orbit a star in exactly the same way, just with the direction of that orbit reversed. But there is one aspect of the universe that is dependent on the direction of Time’s Arrow: the Second Law of Thermodynamics. This states that the disorder of a closed system (such as our universe) must increase, never decrease.
It’s commonly called “entropy,” and it’s why broken eggs don’t suddenly reassemble themselves, or why dead things don’t suddenly come back to life. Disorganization and chaos are downhill, order and complexity are uphill; complex systems like stars and planets and human beings may emerge locally, but they require an inordinate amount of energy to create, which only increases the overall entropy of the system.
This is why the Second Law of Thermodynamics is universally reckoned as the mechanism that imparts directionality to time—although, understanding the how of a thing is not the same as understanding the why of it.
Now, we see the connection of Dark Energy,
In the question to understand the origins of Time’s Arrow, two Armenian physicists, A. E. Allahverdyan and V. G. Gurzadyan, decided to search for a link between so-called “dark energy” and the Second Law of Thermodynamics. Dark energy is a mysterious quantity that is proposed as an explanation for why the universe is continuing to expand, rather than decelerating and collapsing, as our current understanding of gravity dictates it should.
Any electric car maker worth its salt knows that their vehicles are only as good as the charging stations that keep them running… and that includes Apple, apparently. Reuters sources understand that Apple is asking charging station manufacturers about their technology for the sake of its oft-rumored electric car project. It’s not certain how deep the talks go or who’s involved (the companies certainly aren’t talking). However, NRG Energy issued a vague response noting that it’s talking to “every potential manufacturer of tomorrow.” We wouldn’t rule it out, then.
There’s more evidence than that. An unnamed worldwide engineering company has already offered to help Apple build charging stations, Reuters says. Meanwhile, Apple has publicly hired EV charging experts from BMW, Georgia Tech and Google.
If true, the approach is a logical fit for Apple. Part of Tesla’s success in EVs comes from its willingness to build a network of high-speed charging stations — you’re more likely to buy a Model S if you know that you can drive it long distances without spending hours waiting for a recharge. Apple may need that same kind of reassurance. And let’s not forget that Apple’s strategy revolves around controlling as much of the experience as possible. It only makes sense that the company would want optimized charging stations instead of leaving drivers to use generic stations that might not work as effectively.
The US Navy will be taking its futuristic Railgun out of the lab where it has been tested for to past eight years. Over the next two years, railguns will be tested in open firing ranges and eventually at sea, where the futuristic electromagnetic gun will be able to demonstrate its full capacity to fire projectiles at targets 50–100 nautical miles (92 – 185 kilometers) away.
The Navy is evaluating two electromagnetic railgun models. A 32-megajoule prototype built by BAE Systems and the 32 megajoule Blitzer developed by General Atomics Electromagnetic Systems (GA-EMS). The company has also developed a 3-megajoule railgun variant. In the future, the Navy plans to deploy railguns rated to 64-megajoule.
A railgun can deliver muzzle velocities greater than twice those of conventional guns. Using electromagnetic power, where magnetic fields created by strong electrical currents accelerate a sliding metal conductor between two rails, the railgun achieves muzzle speeds of more than Mach 7.5 without the use of chemical propellant.
A more efficient way to mine water and other chemical volatiles to create rocket fuel in situ is arguably the fastest way to colonize the Moon and Mars.
Despite the recent buzz about eventually mining asteroids for metals, their real near-term value may be as space-based sources of water and carbon dioxide from which to make rocket propellant. The trick is in mining such volatile compounds efficiently enough to convert them to fuel in situ. That is, without having to import such resources from gravitationally-bound, planetary surfaces like the Moon, Mars or even Earth.
Here’s where a potentially revolutionary patent pending process dubbed “Optical-Mining” would figure in. The idea is to use this new technology to excavate both water ices and other volatile compounds from small 10 meter-diameter Near-Earth Asteroids. If successful, such an In Situ Resource Utilization (ISRU) asteroid-mining operation could mark the tipping point in viably extracting resources from thousands of such asteroids.
New and improve fuel cells.
Fuel cells, which generate electricity from chemical reactions without harmful emissions, have the potential to power everything from cars to portable electronics, and could be cleaner and more efficient than combustion engines.
