ARC Panel with Marian Tupy: Is Western Energy Policy Causing Economic Self-Harm?
“Beginning in the last decade of the 18th century, firewood output increased from about 18% of GDP to just under 30% of GDP in the 1830s. The value of firewood fell to less than 5% of GDP by the 1880s. Prior estimates of firewood output in the 19th century significantly underestimated its value.”
“Beta Technologies’ Alia CX300 on Tuesday [6/3/25] become the first all-electric aircraft to land at a New York City airport. In partnership with the Port Authority of New York and New Jersey, one of Beta’s prototypes landed at John F. Kennedy International Airport (KJFK) after a passenger-carrying demonstration flight with a pilot and four passengers, including Blade Air Mobility CEO Rob Wiesenthal and Republic Airways president Matt Koscal.
According to Beta, the energy cost for the 45-minute flight was just $7 compared with what it estimated as $160 in fuel costs for a helicopter making the same trip.”

“The U.S. military has set a new record for wireless power transmission, beaming a laser carrying more than 800 watts of power across a distance of 5.3 miles (8.6 kilometers).
The test, performed by the U.S. military’s Defense Advanced Research Projects Agency (DARPA) as part of its Persistent Optical Wireless Energy Relay (POWER) program, is a key step toward unlocking the near-instant beaming of power.
It also smashes previous records set by the POWER program, which previously beamed 230 watts across 1 mile (1.7 km) for 25 seconds, and a smaller, undisclosed amount of power as far as 2.3 miles (3.7 km).”

“A five-minute charge for an EV, virtually as quick as a gasoline fill-up, has long seemed a quixotic dream.
Now electric Don Quixotes can save critical time on their quests, at least in China. BYD’s ‘megawatt charging’ is here. And the company’s 1,000-kilowatt fast chargers could eliminate perhaps the biggest consumer gripe over EVs: That they take too long to charge.
BYD, the automaker that has passed Tesla in global EV sales, demonstrated its record-setting tech in Beijing during the recent Shanghai auto show. The numbers are staggering: More than a kilometer of added driving range per second on the plug. It supplies 400 kilometers of fresh range (nearly 250 miles) in five minutes. Even by the U.S. Environmental Protection Agency’s more-realistic estimates, that equates to about 270 kilometers (168 miles) of range in five minutes.”
