The USB Implementers Forum (USB-IF) this week released the USB Type-C Specification Revision 2.1, and it introduces a welcome (and powerful) new feature.

Existing USB-C cables are capable of delivering up to 100 watts of power, but as The Verge reports, the latest spec revision increases it to 240 watts. The change means future USB-C ports will be able to power and charge a lot more of your kit, resulting in fewer cables and adapters to carry around.

Expect to buy a new cable and charger if you want to take advantage of the extra power.

Charging station manufacturer Tritium (Nasdaq: DCFC) has formed a partnership with Wise EV, a subsidiary of renewable energy service provider Wise Power, to provide DC fast chargers for a new national EV charging network.

The new network is expected to start with 25 locations at Florida gas stations. Florida is the number-two US state for EV sales, and received the third largest state allocation under the new National Electric Vehicle Infrastructure (NEVI) Formula Program Guidance.

Wise EV plans to build its network using a hub-and-spoke strategy, centering the charging around metropolitan hubs and connecting those cities with Interstate highways as spokes. The eventual goal is to build a coast-to-coast charging network. The company plans to establish its metropolitan charging hubs in 2022, and connect those hubs with Interstate charging spokes in 2022 and 2023.

“Sustainable energy solutions simply cannot react instantaneously to make up for Russian oil & gas exports,” Musk said.

In remote desert locations, at least two things are likely to be lacking: an electrical grid, and a source of water for agriculture. An experimental new system addresses both problems, by combining photovoltaic panels with an absorbent hydrogel.

Developed by scientists at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), the setup is known as the integrated water-electricity-crop co-production system – or WEC2P, for short.

It incorporates an array of connected photovoltaic panels, each one of which lies directly atop a layer of hydrogel. Both the panel and the gel form the lid of a downward-sloping metal box, which has a spout at the bottom.

Turbojet engines are an incredible piece of 20th century engineering that except for some edge cases, have mostly been replaced by Turbofans. Still, even the most basic early designs were groundbreaking in their time. Material science was applied to make them more reliable, more powerful, and lighter. But all of those incredible advances go completely out the window when you’re [Joel] of [Integza], and you prefer to build your internal combustion engines using repurposed butane canisters and 3D printed parts as you see in the video below the break.

To understand [Integza]’s engine, a quick explanation of Turbojet engines is helpful. Just like any other internal combustion engine, air is compressed, fuel is burned, and the reaction produces work. In a turbojet, a compressor compresses air. Fuel is added in a combustor and ignited, and the expanding exhaust drives a turbine that in turn drives the compressor since both are attached to the same shaft. Exhaust whose energy isn’t spent in turning the turbine is expelled and produces thrust, which propels the engine and the vehicle it’s attached to in the opposite direction. Simple, right? Right! Until the 3D printer comes in.

With the war in Ukraine raging and gas and energy prices climbing across world markets, there is one piece of good news for European energy markets.

Economists from Poland’s state Pekao bank are reporting a large reduction on the price of CO₂ emission certificates. The prices have fallen dramatically from €95 to €62 per ton. This is especially good for countries like Poland, which are forced to pay a premium for energy derived from “dirty” sources like coal. The fall in the price of this “tax” is expected to make the cost of energy especially more bearable for many of Europe’s poorer nations.

The CEO of Poland’s Development Fund, Paweł Borys, also commented on the issue on Twitter. “It is significant how CO₂ prices have collapsed, falling by 30 percent since they peaked in February. This is good news, as it means that electricity prices may fall, thereby reducing inflationary pressure that have been exacerbated by hikes in oil and food prices.”

A global hunt for spare barrels of crude is underway as sanctions slam Russia, the world’s second largest exporter, following its invasion of Ukraine.

But don’t expect Saudi Arabia to step in to fill the gap, at least for now.

What’s happening: The kingdom could help ease global oil prices, which have spiked to their highest level since 2014. Saudi Arabia has the capacity to raise production by 2 million barrels per day, according to Claudio Galimberti, senior vice president of analysis at Rystad Energy.

Today we can eliminate landfills by incinerating much of the garbage we produce using net-zero-emissions waste-to-energy technologies.
