Energy Internet What is ? According to the description of " Third Industrial Revolution " in 2011, American scholar Jeremy Rifkin combined two revolutionary technologies of new energy and information to generate a new energy utilization system. He named the idea Energy Internet, that is, the energy Internet.
In 2014, China proposed a long-term strategy for the revolution in energy production and consumption, and tried to dominate the layout of the global energy Internet with the power system as the core.
September 1, professor at Tsinghua University Sun Hongbin said at a forum on new energy technology that the energy Internet is a "disruptive technology" with the goal of promoting better connectivity and open sharing of energy, promoting the construction and development of green energy, and thus reducing carbon emissions.
Energy Internet can expand to all aspects of society, not limited to energy conservation and emission reduction, but also has huge development potential in the military.
htmlOn October 5, the U.S. Department of Defense Advanced Research Projects Agency (DARPA) declared that their researchers are studying the next leap in energy allocation, creating a dynamic, adaptive, light-speed wireless energy network by leveraging wireless power transmission.
The program is called POWER (Persistent Optical Wireless Energy Relay), and aims to design and demonstrate airborne optical energy relays that can realize the future multipath wireless energy network.
This challenge is based on the use of a flexible multi-path network for energy flowing from a wealthy source to a place of consumption where energy is scarce. In this way, the wireless power network changes the energy delivery path from the "container" type of traditional liquid fuel to the "pipe" type, which is also the core of the POWER project.

is a more subsequent challenge. POWER will also use relays to improve the technical level of power transmission to improve the conversion efficiency. It is not easy to implement
at present, because in the network, the propagated waves are converted back to the power and then converted into the propagated waves at each node, because each conversion is relatively inefficient and will cause unacceptable losses.
History shows that every breakthrough in energy transmission will bring about disruptive changes. From military to civilian use, it will greatly shorten the energy delivery time. Researchers say that wireless energy networks achieve the next leap in energy distribution, providing distributed services to terminal energy consumers in sea, land, air and space.
