The $190K ‘Flying Car’ That Doesn’t Require a Pilot’s License | WSJ Tech Behind
Electric vertical takeoff and landing aircrafts, or eVTOLs, promise a futuristic vision of the world. One company, Pivotal, is taking a different approach with an eVTOL looks different from the rest of the market. Their ultralight consumer eVTOL weighs just 348 pounds, has eight propellers and does not require a pilot’s license to operate.
WSJ explores how Pivotal’s ultralight eVTOL works.
We Said Goodbye to the Power Grid… Forever
This is the full tour of our off-grid solar power system. We’ve been off-grid for over a year now and it’s so rewarding!
What caused Spain and Portugal’s power cut? | BBC News
Spanish power company Red Eléctrica has ruled out a cyber-attack as the cause of Monday’s mass blackouts, that left millions across Spain and Portugal without power.
Portuguese Prime Minister Luis Montenegro also said there was no indication that a cyber-attack was behind the outages.
Electric grids suffered two “disconnection events” – systems recovered from the first, but the second triggered the power cuts in both Spain and Portugal, with no indication of human error.

Infinite Range Electric Car – DIY Build
Ever wondered why we can’t make an electric car that’s fully powered by solar panels to provide an unlimited range? This video is a lighthearted take on building an infinite range electric car that uses solar panels to provide unlimited energy. The car has dual 3000W ebike motors to reach a maximum speed of 45 km/h, a 48v 4000w/h LifePO4 battery, 1575w of total solar production.
Why China is winning the EV war
The Biden administration set a climate goal that 50 percent of all new car sales in the US would be electric by 2030. Meanwhile, China reached that milestone this year, in 2024. This video explains how China was able to fast-track EV adoption and develop an EV battery that rivals what any other country has been able to do so far. It’s been a decade of government strategies that have created some of the biggest battery companies in the world, like CATL and BYD. The Biden administration wants to keep Chinese cars and batteries out of the country — but our video explains what kind of position that puts the US in in terms of meeting its own climate goals.
What Really Happened During the 2003 Blackout?
In 2003, one of the most severe power outages in history affected the northeastern US and parts of eastern Canada. This video summarizes the events leading up to and during the blackout.
