Pebble Flow electric RV towed by TELO’s MINI-sized electric truck

14 July 2026 at 17:10

Pebble has answered its most common customer question — what’s the smallest vehicle that can tow the Flow electric travel trailer — with a MINI Cooper-sized electric pickup.

The company posted photos of TELO’s MT1 electric truck pulling its full-size, 5,800-lb Flow trailer, a pairing made possible by the Flow’s own active propulsion system.

Solution to Feynman's reverse sprinkler puzzle also applies to "silly sprinklers"

13 July 2026 at 20:00

Watering your lawn in the summer can be both pragmatic and fun with so-called "silly sprinklers," designed to create amusing loops and spirals of water jets. And there's some fascinating physics at work to boot. Researchers at New York University's Courant Institute conducted a series of experiments with different silly sprinkler designs to find the answer to a longstanding problem in fluid dynamics, according to a new paper published in the Proceedings of the National Academy of Sciences.

As previously reported, the reverse sprinkler problem is associated with physicist Richard Feynman because he popularized the concept, but it actually dates back to a chapter in Ernst Mach’s 1883 textbook The Science of Mechanics (Die Mechanik in Ihrer Entwicklung Historisch-Kritisch Dargerstellt). Mach’s thought experiment languished in relative obscurity until a group of Princeton University physicists began debating the issue in the 1940s.

Feynman was a graduate student there at the time and threw himself into the debate with gusto, even devising an experiment in the cyclotron laboratory to test his hypothesis. One might intuit that a reverse sprinkler would work just like a regular sprinkler, merely played backward, so to speak. But the physics turns out to be more complicated. “The answer is perfectly clear at first sight,” Feynman wrote in Surely You’re Joking, Mr. Feynman (1985). “The trouble was, some guy would think it was perfectly clear [that the rotation would be] one way, and another guy would think it was perfectly clear the other way.”

BYD wins 11.3 GWh battery deal for world’s largest solar+storage

10 July 2026 at 14:25

BYD Energy Storage has landed a contract to supply 11.275 GWh of battery storage for Masdar’s Round the Clock (RTC) project in Abu Dhabi — one of the single largest energy storage procurements ever signed.

The RTC project pairs a 5.2 GW solar array with a 19 GWh battery system, making it the world’s largest combined solar-plus-storage plant. BYD’s award covers the majority of that storage.

How Fast Does Information Travel to Earth from the Outer Most Reaches of the Cosmos?

1 July 2026 at 09:54
Astronomers using the James Webb Space Telescope have observed extremely distant LRD galaxies, with redshifts greater than 14 at distances greater than 13.5 billion light-years. The question I raise here is how do we see these galaxies and their spectral features if the universe is less than 10,000 years old?

Why Did the US Government Brief Groups of Christian Pastors About UFOs and Aliens?

26 June 2026 at 03:43
In February 2026, President Trump directed the U.S. government to release documents on UFOs, UAPs, and alien life. Questions arise about the nature of these phenomena, ranging from interdimensional entities to possible deceptions involving spiritual beings, echoing long-standing debates on extraterrestrial existence and their implications for faith.

A curious crossover: The Toyota C-HR review

23 June 2026 at 19:19

After a slower start than its major rivals, Toyota has been making up for it with a flurry of new electric vehicles for the North American market. Its first attempt, the bZ4x, was an also-ran, but a new battery pack, more efficient motors, and a NACS charging port transformed the face-lifted bZ into an EV I happily recommend. Then, earlier this year, it followed up with some bZ-related variants. For those who miss the vibe of a station wagon, there is the bZ Woodland, and an all-electric Highlander is nearing the showroom, too. But today's focus is the C-HR, and I'm still not entirely sure what to make of it.

It's the smallest of the bunch, some 6.7 inches (170 mm) shorter than the bZ. But it's still as wide and only a little more than an inch shorter. So if you're put off by the bZ's size and are looking for something diminutive—and based on reader feedback, there are many of you out there—this small SUV will probably still fail to pass muster.

It's not any cheaper than the bZ until you consider that the C-HR is only available with one choice of powertrain: a twin-motor AWD setup with a combined 338 hp (252 kW) powered by a 74.7 kWh battery pack. That same arrangement, with a 223 hp (167 kW), 198 lb-ft (268 Nm) front motor and 118 hp (88 kW), 125 lb-ft (169 Nm) rear unit, costs almost $3,000 more in a bZ than the $37,000 starting price of the C-HR.

ABC asks viewers to protest FCC attempt to "control who is allowed" on The View

23 June 2026 at 18:59

ABC is urging viewers to write to the Federal Communications Commission and tell it to stop trying to "control who is allowed to appear" on The View. An ABC commercial that started airing yesterday asked viewers to submit responses to the FCC's call for public comment on whether the talk show is a “bona fide news interview program.”

"The View has welcomed your favorite guests and covered the issues you care about for nearly 30 years," ABC's ad said. "Now, the FCC wants to control who is allowed on the show. Viewers, use your voice. Tell the FCC to let the viewers decide."

For decades, the FCC has classified late-night and daytime entertainment talk shows as bona fide news for the purposes of their interview segments. This makes the shows exempt from the equal-time rule, which requires equal opportunities for opposing political candidates on non-news programming.
