How One Builder Created a Hybrid Generator for Boats

By Bill Smith June 29, 2026

Daniel Riley spends his days turning ordinary hardware into machines that do more than expected. His latest project takes a small four-stroke engine of the type found on string trimmers and connects it to an electric motor normally used in skateboards. The result is a compact generator that produces up to 780 watts of electrical power. Installed in a boat, the assembly becomes the core of a hybrid drivetrain built around one clear goal: keep the gasoline engine running where it works best while the electric side manages everything else.

NASA Tests Cryocoupler Device That Could Let Spacecraft Top Off Fuel Their Tanks in Orbit

By Jackson Chung June 29, 2026

Space missions have long been constrained by the amount of propellant rockets can haul off the launch pad. NASA sees a path around that limit through refueling stops once a craft reaches orbit. Engineers at Marshall Space Flight Center in Alabama recently put a new connector through its first serious checks. The device, called a cryocoupler, would let two spacecraft link up so one can pass super-cold liquid fuel to the other while both float in space.

China’s Huajiang Grand Canyon Bridge is Now World’s Highest, Boasts Massive Artificial Waterfall

By Jackson Chung June 29, 2026

China’s Guizhou province has once again made a name for itself by going overboard with extreme infrastructure; the Huajiang Grand Canyon Bridge is a new addition to the list as the world’s highest bridge, with its roadway dangling 625 meters over the Bei Pan River. Drivers may pass by in about a minute flat, which represents a big improvement over historic mountain roads and ferry crossings that used to take more than an hour if they were fortunate.

Unitree R1 Offers Humanoid Movement at a Price That Finally Opens the Door for Real-World Buyers

By Jackson Chung June 28, 2026

Unitree has finally begun shipping its R1 humanoid robot to customers around the United States. It stands 123 centimeters (4 feet) tall and has an extremely slim body, measuring 357 millimeters across the shoulders. It weighs between 27 (60 lb) to 29 (64 lb) kilos and is reasonably lightweight, thanks to Unitree’s use of low-inertia motors and a framework that is simply designed to be extremely easy to maintain, rather than heavy-duty industrial armor.

Building a Star Wars Galaxy With Cardboard and Ten Dollars

By Bill Smith June 28, 2026

A fresh new fan film by Secondhand Movie Co takes Star Wars back to its roots and reworks them with absolutely no production value. The original 1977 film had a budget of little under eleven million dollars, which is roughly equivalent to sixty million today. However, this version must make do with microscopic fraction of that, or ten dollars. As a result, the sets, costumes, and the majority of the props are built out of cardboard.
