Pebble Flow electric RV towed by TELOโ€™s MINI-sized electric truck

14 July 2026 at 17:10

Pebble has answered its most common customer question โ€” whatโ€™s the smallest vehicle that can tow the Flow electric travel trailer โ€” with a MINI Cooper-sized electric pickup.

The company posted photos of TELOโ€™s MT1 electric truck pulling its full-size, 5,800-lb Flow trailer, a pairing made possible by the Flowโ€™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 Machโ€™s 1883 textbook The Science of Mechanics (Die Mechanik in Ihrer Entwicklung Historisch-Kritisch Dargerstellt). Machโ€™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.ย 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. โ€œThe answer is perfectly clear at first sight,โ€ Feynman wrote in Surely Youโ€™re Joking, Mr. Feynman (1985). โ€œThe 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.โ€

BYD wins 11.3 GWh battery deal for worldโ€™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 Masdarโ€™s Round the Clock (RTC) project in Abu Dhabi โ€” 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 worldโ€™s largest combined solar-plus-storage plant. BYDโ€™s award covers the majority of that storage.

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

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.
