BYD's New 'Megawatt' EV Charging Is So Fast It Makes Gas Irrelevant
After revealing EVs that could charge at up to 500 kilowatts, Chinese carmaker BYD says its new tech allows up to 1,000 kW charging power, which can replenish range at a rate of 1.2 miles per second.
According to the company, Super e-Platform runs at 1,000 volts, which is higher than even the highest voltage of the current crop of EVs which peak around 800 volts or 900 volts.
BYD’s new platform can also take up to 1,000 amps of current, enough to add 249 miles of range in just five minutes. That’s almost as quick as putting fuel in a combustion vehicle, eliminating one of the biggest EV drawbacks – the need to wait around often for dozens of minutes for them to make meaningful range gains while plugged in.
Special charging stations with beefy specs are required to achieve the maximum charging power, but BYD has announced its plan to build 4,000 of them around China. The manufacturer didn’t say when it would start building these stations, and it didn’t give a time frame for the completion of the planned 1,000 kW network.

Wearable Ring Translates Sign Language Into Text
By combining deep learning artificial intelligence (AI) and micro-sonar technologies, researchers at Cornell University are developing a new wearable to help overcome the communication barriers. With further refinement, SpellRing may one day facilitate entire conversations regardless of your American Sign Language (ASL) comprehension skills.
SpellRing builds off a previous iteration called Ring-a-Pose and relies on multiple inputs to analyze, interpret, and translate ASL fingerspelling gestures. The principle component is a quarter-sized 3D-printed ring casing that contains a small microphone and speaker, and is worn around the thumb.
When the user begins fingerspelling, the microphone emits inaudible soundwaves that are subsequently detected by the microphone as a miniature gyroscope measures the hand motions. Meanwhile, a computer featuring a deep-learning algorithmic program analyzes and translates the resultant sonar images into individual letters in real-time on a computer screen.
Researchers trained SpellRing with the help of 20 experienced and novice ASL signers as they spelled out over 20,000 words. Depending on length and difficulty, SpellRing’s accuracy eventually ranged from 82% to 92%.

The 100X AI Boom
Yesterday, Nvidia CEO Jensen Huang took the stage at the company’s annual GPU Technology Conference (GTC) and addressed head-on the investor unease sparked by January’s release of DeepSeek, a Chinese AI model touted as needing fewer Nvidia chips.
Huang flipped the narrative, arguing that the next wave of AI – spanning reasoning models and AI agents – will demand 100 times more computational power than previously anticipated. This vision of sustained, even escalating demand for Nvidia’s GPUs counters the DeepSeek-driven selloff narrative and paints a picture of a company poised for explosive growth.
The conference also saw Huang drop the bombshell of the Rubin AI superchip, slated for mid-2026, which boasts over three times the Blackwell Ultra’s power, with an even mightier Rubin Ultra variant to follow in 2027 offering 14 times Blackwell’s performance.
Yet, despite these blockbuster updates, Nvidia’s stock dipped 3% yesterday, caught in a broader tech selloff tied to geopolitical and economic tensions.
If you don’t already own Nvidia, now is your chance to get in. The selloff has created a rare entry point for a company with a clear path to dominate the AI-driven future.
