Electric supercars need to lose weight, power up and cool down

-
By Nick Carey and Giulio Piovaccari
OXFORD (Reuters) - Speed has always been paramount for supercar makers, and now they're in the race of their lives to go electric before climate policy cuts their combustion engines.
That's why the likes of Ferrari and Mercedes-Benz are turning to startups such as Oxford-based electric motor company YASA for expertise and technology to solve the unique challenges of electrifying the highest-performance vehicles.
Batteries are immensely heavy and electric motors overheat if driven too hard - big problems for a niche industry that charges hundreds of thousands of dollars for lightweight cars capable of screaming round 10 laps of a track at full throttle.
This year Daimler bought YASA, which has developed an "axial flux" high-performance electric motor that weighs 23 kg (50.7 lb), ...

By AI Trends Staff     As the  US Navy  strives to get to a 355-ship fleet by 2034, part of a 30-year plan the Navy outlined in 2019, it is finding it economical to use underwater autonomous vehicles. They meet many of the requirements of larger submarines at a fraction of the cost.     For example, the Navy awarded Boeing a $43-million contract to build four Orca Extra Large Unmanned Undersea Vehicles (XLUUVs) last year, described in a release from  USNI News .      Boeing based its winning Orca XLUUV design on its Echo Voyager unmanned diesel-electric submersible. The 51-foot-long submersible is launched from a pier and can operate autonomously while sailing up to 6,500 nautical miles without being connected to a manned mother ship, according to the Navy.   In military spending terms, the versatility of the Orca at the price is “fairly unheard of in military spending,” according to an account in  The National Interest . The nearest equivalent was cited as the Navy’s Littoral Com

Canada regulator seeks information from public on Rogers-Shaw deal

-
(Reuters) - A Canadian regulator on Tuesday asked for information from the public on telecom company Rogers Communications Inc's planned C$20 billion ($16 billion) purchase of Shaw Communications Inc to check for competition concerns. The deal announced in March to create Canada's second-largest cellular and cable operator has attracted regulatory scrutiny. The Competition Bureau said in August it obtained court orders to advance its review. The regulator on Tuesday asked market participants and Canadians to come forth with information that could assist the regulator's probe on whether the deal will reduce or prevent competition. The Competition Bureau said its review was ongoing and no conclusions have been made. ... Read More on Datafloq
