Rocket Explodes Seconds After Launch
Posted in drones, energy, satellites
A Japanese rocket by startup Space One has exploded in spectacular fashion following a launch attempt earlier today.
It’s yet another major setback for the company, which was hoping to become Japan’s first commercial entity to launch a satellite into orbit, the New York Times reports.
Drone footage shows the dramatic scene. At first, everything appears to go fine as the solid-fuel rocket dubbed Kairos lights its engines. But it doesn’t take long for the rocket to seemingly veer off path, erupting into a massive cloud of smoke just seconds later, causing major pieces of debris to rain down on the launch pad and engulf parts of the facility and a neighboring forest in flames.

Invisible vacuum energy is all around us. We could use it to power propulsion, enhance nanostructures, and build levitating devices.
Space may be the final frontier, but we can’t go far on rocket fuel. Now, two scientists are working on a device that may one day make the \.
A hydrogen fuel-cell passenger train developed by Swiss rail vehicle maker Stadler Rail has achieved a new Guinness World Record, traveling for almost two days around the clock for a distance of 1,741.7 miles.
Efforts to clean up dirty trains are already well underway, with heavy investment in electrifying networks around the world as well as rolling out battery-electric locomotives such as the FLXDrive, the Blues train and the Flirt Akku.
That last example is made by Stadler Rail AG, and managed to achieve a Guinness World Record in 2021 for the longest per-charge battery-only journey of 224 km (~140 miles), on a route between Berlin and Warnemünde during a freezing local winter – not bad for a train that was designed with an operational per-charge range of 80 km.
Clean Power and Electrification

It ‘flies’ in a figure-of-8 pattern against the tidal flow.
The World Economic Forum’s Clean Power, Grids and Electrification initiative is focused on delivering a rapid and responsible energy transition.
The startup emerged from stealth with a goal of extending the range of EVs while also eliminating fossil fuels from home heating.
The attempt began on the evening of March 20, and GWR officials were present at the test site. Engineers from Stadler drove the train in shifts over the night and the following day. When the train stopped at 5:23 pm on March 22, it had traveled 1,741.7 miles (2,803 km) over 46 hours, all on a single fuel tank.
This is six times the distance of FLIRT H2’s advertised range – 285 miles (460 km). However, it is unlikely to be replicated in real-life scenarios since the train did not stop and start multiple times during the record attempt, nor did it travel on different inclines. Nevertheless, it showcased the ability of hydrogen fuel as a potential power source for trains.
