Kraaken combines ocean thermal generation, AI computing, freshwater production and storm mobility in one offshore platform. The engineering question is whether all of those physical flows and interfaces can reconcile in the same 100 MW system.
A floating data centre that generates its own electricity from the ocean, cools itself with seawater, produces drinking water for a coastal community and can sail away when a hurricane approaches is almost tailor-made for the current AI data center hype bubble. Optimal Transit’s Kraaken concept is ambitious even by … [continued]
HyFlux’s superconducting motor could substantially improve propulsion power density, but its commercial value still depends on the aircraft, cryogenic fuel system and airport infrastructure around it.
HyFlux has an unusually interesting hydrogen-aviation proposition because the technology at its centre appears somewhat credible, if incredibly difficult to engineer and maintain. The UK company wants to exploit the extreme cold of liquid hydrogen already carried aboard a future hydrogen aircraft to cool a fully superconducting electric motor. Superconductivity … [continued]
For the same 25 MW / 100 MWh four-hour service, Energy Vault’s Rudong project requires far more capital, land, machinery and construction carbon than a contemporary Chinese BESS.
Energy Vault’s Rudong gravity-storage project is a particularly useful technology test because it removes many of the excuses that can surround a first-of-kind energy project. It was built in China, with deep domestic supply chains for concrete, steel, motors, power electronics and industrial construction. It had government support, grid coordination … [continued]
Vertical’s Farnborough flights demonstrated real engineering progress. Five years after listing, outside capital still funds the path toward certification and an unproven passenger market.
Vertical Aerospace’s July appearance at the Farnborough International Airshow was a real engineering milestone. The company publicly demonstrated piloted transition between vertical and wingborne flight, something a powered-lift aircraft has to do safely and repeatedly before certification can advance. Vertical then flew on successive days in front of a large … [continued]
Carney’s industrial strategy is strongest where government builds shared productive capacity and leaves firms and technologies to compete over how it is used.
Mark Carney’s industrial-policy agenda has reopened a debate Canada never really escaped: when should government build, finance or shape productive capacity, and when should it leave the result to markets? The proposed C$25 billion Canada Strong Fund makes the question concrete because Ottawa would borrow to capitalize an investment vehicle … [continued]
Heart Aerospace’s X1 represents the less glamorous but more consequential aviation transition: electrifying an existing market rather than inventing a new one.
Heart Aerospace’s X1 demonstrator flew for 27 minutes on August 12 from Plattsburgh International Airport, powered entirely by batteries. The aircraft has a 106-foot wingspan, weighed more than 25,000 pounds at takeoff and drew more than a megawatt at peak. Heart calls it the largest battery-electric aircraft ever flown. The … [continued]
GeoPura’s sellers receive only £82.5 million in cash and mostly Ballard shares, while employees inherit the execution risk of the next hydrogen dilution cycle.
Perpetual loss-making hydrogen fuel cell firm Ballard Power is paying £275 million for GeoPura, but only £82.5 million is cash. Most of the price is 50.8 million newly issued and dilutive Ballard shares, leaving GeoPura’s investors with about 14.4% of the combined company and subjecting much of their consideration to … [continued]
CleanTechnica’s authors write often about their experiences with electric vehicles. They detail experiences as they go off with spouses, children, friends, and even dogs. I wish I could do that, but I don’t have an EV — or any car at all. In fact, I don’t even drive. So, I … [continued]
Hyliion takes staging to a fine art at their 2023 Investor Day, but the real news is that production has officially begun.
For the first time in over a decade, the cost of producing a kWh of battery capacity has gone up!
