Michael Levin's NeurIPS 2018 talk on bioelectric computation outside the nervous system, showing how cell electrical networks shape development and regeneration. It covers morphological information processing in living tissue.

Biologist Michael Levin explains the bioelectric layer that coordinates cells to build organs and bodies, showing footage of two-headed worms and introducing xenobots. He discusses implications for medicine and the nature of life.

Veritasium argues that electric energy is carried by fields around the wires rather than by electrons moving through them, using a thought experiment with a large circuit.

Real Engineering analyzes whether electric planes are feasible, focusing on battery energy density limits compared with jet fuel. It concludes electric flight works mainly for short ranges.

Robert Llewellyn of Fully Charged takes an early, 19-minute test drive of the Honda e electric car in Frankfurt. He looks at its acceleration, camera wing mirrors and tight turning circle.

Fully Charged episode where Elliot drives the NIO ES8 SUV and visits a battery swap station that replaces the pack in about three minutes. It covers the ownership model of swapping and what it could mean for EV charging.

Engineering Explained works through whether electric cars are really worse for the environment than gasoline cars. It covers battery production emissions, the electricity mix used to charge, and how long an EV takes to break even on lifetime emissions.

A motorcycle safety video on the SMIDSY (sorry mate, I didn't see you) accident, explaining the perception and optical illusion that makes drivers fail to see riders, and how riders can spot the signs and avoid it.

Technology Connections explains that the so-called EV charger in an electric car's charging cable or wall unit is really an EVSE, a smart switch that safely delivers AC power. The actual charger is inside the car. The video covers the safety signaling and mechanisms involved.

Technology Connections' hour-long guide to electric vehicles, covering costs, trade-offs and especially how little home charging power most drivers need.

Doug DeMuro reviews the Rivian electric delivery van built for Amazon, walking through its quirks, features and design innovations. It is a long, detailed tour of the vehicle inside and out.

Sandy Munro sits down with engineers from 3IS to compare the electrical architectures of the Tesla Model Y, Ford Mach-E and VW ID.4. They discuss ECU counts, bus architectures and what the differences mean for cost and integration.

Engineer Sandy Munro joins an Autoline panel for a 100-minute deep dive on Tesla's design and manufacturing, including the Model 3 and its motors.

Tom Scott borrows a Nio electric car in China and shows its automated battery swap station replacing the whole battery in minutes. He explains how swapping serves as an alternative to charging.
