Korean engineers have demonstrated a new system that uses infrared lasers to beam power over distances as far as 100 ft (30 m), which could eventually lead to technology that automatically charges your phone as soon as you walk into a room.
-
The first generation-IV nuclear reactor design has been approved for certification by the US Nuclear Regulatory Commission. NuScale's small modular reactor design promises safe, clean energy at radically reduced cost, land use and installation time.
-
It was back in 2015 that Tesla unveiled its Powerwall battery energy storage system for the home. Well, Toyota has now announced its similar O-Uchi Kyuden System, which can draw power from EVs.
-
As the number of electronic devices grows, we have to get creative with our energy sources. Cambridge researchers have now demonstrated how an algae energy harvester can use sunlight to power a microprocessor for over a year without any intervention.
-
In what it describes as the most significant demonstration of its kind in half a century, the US Naval Research Laboratory (NRL) beamed 1.6 kW of power over a kilometer (3,280 ft) using a microwave beam at the US Army Research Field in Maryland.
-
Oxford-based UK tech firm Tokamak Energy has reached a milestone in privately-funded fusion research after its ST-40 spherical tokamak reactor reached a temperature of 100 million °C (180 million °F), the threshold for commercial fusion energy.
-
Widespread wireless charging could one day keep our devices juiced up indefinitely. A new breakthrough has been made in that direction, as researchers in Japan have developed a system that can turn a whole room into a wireless charger.
-
Norway's Wind Catching Systems has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world's biggest single turbines – while reducing costs to be immediately competitive.
-
Bill Gates's next-level nuclear power station is small, cheap, efficient and fast to build. It also has a built-in, on-demand energy storage system 10 times bigger than the biggest grid-scale batteries. Thanks to a DoE grant, it will open before 2030.
-
A surprisingly simple new energy storage system is built on blocks that store thermal energy like melted chocolate chips in a muffin. The team says they’re efficient, scalable, safe, inexpensive, and can be used in existing coal-fired power plants.
-
A New Zealand-based startup has developed a method of safely and wirelessly transmitting electric power across long distances without the use of copper wire, and is working on implementing it with the country's second-largest power distributor.
-
The US Department of Defense (DOD) has awarded contracts to three companies to develop mobile nuclear microreactors for military applications under a Strategic Capabilities Office (SCO) initiative called Project Pele.
