MIT spin-off Quaise says it’s going to use hijacked fusion technology to drill the deepest holes in history, unlocking clean, virtually limitless, supercritical geothermal energy that can re-power fossil-fuelled power plants all over the world.
These smaller 5G antenna setups are coming to more cities.
AT&T is expanding tests of small cell 5G radios that can discreetly hide on top of city street light posts without extra power or boxes. The technology was developed in partnership with Ericsson and Ubicquia.
These Arduino-compatible handheld kits transmit chat messages and GIFs over long ranges, encrypted for privacy.
The material could replace rare metals and lead to more economical production of carbon-neutral fuels.

The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting. Humanity isn’t even at Type 1, yet.
Coin cells are useful things that allow us to run small electronic devices off a tiny power source. However, they don’t have a lot of capacity, and they can run out pretty quickly if you’re hitting them hard when developing a project. Thankfully, [bobricius] has just the tool to help.
The device is simple – it’s a PCB sized just so to fit into a slot for a CR2016 or CR2032 coin cell. The standard board fits a CR2016 slot thanks to the thickness of the PCB, and a shim PCB can be used to allow the device to be used in a CR2032-sized slot instead.
It’s powered via a Micro USB connector, and has a small regulator on board to step down the 5 V supply to the requisite 3 V expected from a typical coin cell. [bobricius] also gave the device a neat additional feature – a pair of pads for easy attachment of multimeter current probes. Simply open the jumper on the board, hook up a pair of leads, and it’s easy to measure the current being drawn from the ersatz coin cell.
Building a better supercomputer is something many tech companies, research outfits, and government agencies have been trying to do over the decades. There’s one physical constraint they’ve been unable to avoid, though: conducting electricity for supercomputing is expensive.
Not in an economic sense—although, yes, in an economic sense, too—but in terms of energy. The more electricity you conduct, the more resistance you create (electricians and physics majors, forgive me), which means more wasted energy in the form of heat and vibration. And you can’t let things get too hot, so you have to expend more energy to cool down your circuits.
Whoop Energy and XCel Power have ceased trading – affecting around 550 customers.
Consumers from both energy firms will be designated a new supplier by market regulator Ofgem – through its supplier of last resort process.
Whoop Energy (Whoop) provides gas and electricity to 262 customers, including 50 households (domestic consumers).
New applications in energy, defense and telecommunications could receive a boost after a team from The University of Texas at Austin created a new type of “nanocrystal gel”—a gel composed of tiny nanocrystals each 10,000 times smaller than the width of a human hair that are linked together into an organized network.
