Amputee Makes History with APL’s Modular Prosthetic Limb

Holy crap, this is brilliant. Johns Hopkins is making miracles. – A Colorado man made history at the Johns Hopkins University Applied Physics Laboratory (APL) this summer when he became the first bilateral shoulder-level amputee to wear and simultaneously control two of the Laboratory’s Modular Prosthetic Limbs. Most importantly, Les Baugh, who lost both arms in an electrical accident 40 years ago, was able to operate the system by simply thinking about moving his limbs, performing a variety of tasks during a short training period.

Exposing The Solid State Donut Battery. It’s Over.

Here is the video, and below is some info from Grok relating to Ziroth, the YouTube channel.

From Grok…

Ziroth is a popular YouTube channel (@ZirothTech) focused on energy engineering, clean tech innovations, and technologies that support the transition to a zero-carbon future.

Key Details

  • Creator/Founder: Dr. Ryan Inis Hughes (often referred to as Ryan Hughes), a multidisciplinary engineer with a PhD. He started the channel in 2020 while working on his thesis and has since built it into a team effort with animators, editors, researchers, and staff. ziroth.com
  • Subscribers: Around 500K–505K as of recent data (it has grown steadily past 400K). youtube.com
  • Videos: Roughly 127 videos, plus Shorts. Total views exceed 85 million. socialblade.com

Content Style and TopicsThe channel highlights exciting science and engineering projects in areas like:

  • Batteries and energy storage (e.g., sodium batteries, solid-state claims, thermal storage)
  • Electric motors and propulsion (superconducting motors, high-efficiency designs for aviation/transport)
  • Electrification and power technologies
  • Broader clean tech, renewables, and efficiency innovations

Videos often feature in-depth analysis, animations, interviews with inventors, and critical examinations of hype vs. reality. Ryan emphasizes accurate science reporting and factual evidence.

luvkilomedia.comRecent/Popular Videos include:

  • Exposés on questionable claims (e.g., “Exposing The Solid State Donut Battery”)
  • Breakthrough coverage (e.g., CATL’s sodium batteries, ultra-efficient motors, bionic/revolutionary engineering) youtube.com

The tone is optimistic about green tech progress but skeptical of over-hyped or misleading claims.

Huge 3D Printed Variable Pitch Quadcopter

From YouTube – rctestflight explores the potential of low disc loading to improve drone efficiency by designing and building a custom quadcopter with oversized, variable-pitch rotor blades. Using 3D-printed parts and belt-driven motors, the project investigates whether this unique propulsion configuration can offer a viable alternative to conventional, high-RPM multirotor designs.
