Engineers Test a Jet Engine That Ran 70 Hours on Zero Fuel Using Plasma For over a century, jet engines have relied on combustion—burning fuel to generate thrust. Now, engineers are challenging that foundational principle with experimental tests showing a jet engine operating for 70 hours without traditional fuel, using superheated plasma instead of combustion. This breakthrough represents a radical shift in propulsion research. By using electrically generated plasma to energize airflow, scienti

Have you ever seen a "Cab Beside Engine" truck? 📜🚛 This is the Kenworth CBE (Cab-Beside-Engine), a rare design from the late 1950s that tried to revolutionize trucking. unlike the standard Cabover (COE), this design placed the driver to the left of the engine. Why did they build it? Weight: It saved about 700 lbs, allowing for more freight payload. Maintenance: Mechanics didn't have to tilt the cab; they just removed a side panel to access the Cummins 175 HP turbodiesel. Visibility: The driver
