Evans Electric Pty Ltd
Evans Electric Pty Ltd is a Sydney-based electric machine developer founded by Paul Evans that designs high torque density axial flux induction motors, integrated eAxles, silicon-carbide motor controllers and electromechanical actuation systems for electric vehicles, aerospace propulsion, heavy equipment and industrial platforms. Its patented double-stator, single-rotor axial air-gap architecture aims to deliver the same performance as conventional motors in roughly a third of the volume.
Cool Earth Solar
Cool Earth Solar is a California solar company with two lives: it launched in 2006 as a venture-backed clean-energy startup chasing utility-scale power with cheap, air-inflated plastic concentrator dishes, then evolved into a locally owned residential and commercial solar installer serving the Stockton-to-Placerville corridor. Today it designs, engineers, and installs solar power and battery storage systems in-house - no outsourcing - under CEO Rob Lamkin, and has been a recognized SunPower dealer, winning national and regional dealer awards.
Schiller Bikes
Schiller Bikes (Schiller Sports, Inc.) is a Mill Valley, California company that makes the S1-C, a premium human-powered water bike. Built on a corrosion-resistant anodized aluminum catamaran frame with a Gates Carbon Drive belt, a proprietary gearbox and a retractable propeller, the bike lets a rider pedal across lakes, coastlines and open water at over 10 mph. Founded by Jessica Schiller after she became the first person to bicycle across San Francisco Bay in 2013, the company built a small, design-led business around a niche it largely invented: a real cycling experience on the water for fitness, exploration and fun.
Duranium
Duranium is a Y Combinator (S25) advanced-materials company reshoring U.S. production of critical metals - titanium, magnesium, aluminum, zirconium and hafnium. It modernizes carbochlorination metallurgy with a novel reactor that recirculates CO and chlorine streams back into feedstock and spins off a saleable co-product (bleaching agents/hypochlorite), aiming to match Chinese-level pricing without subsidies while eliminating direct emissions. Founded in 2025 by CEO Brenden Prins-McKinney and CTO Berkley Noble, the company targets a pilot facility by June 2026 and roughly 12% of the U.S. magnesium market by 2029.
Advanced Battery Concepts
Advanced Battery Concepts is a Clare, Michigan battery maker that did something contrarian: instead of chasing lithium, it went back to lead-acid and reinvented it. Its patented GreenSeal bipolar architecture cuts lead content while boosting cycle life, and the company has licensed the design to global battery giants like Clarios, EnerSys, Exide, Crown and Trojan. With its EverGreenSeal line and BatteryBarn utility systems, ABC builds non-flammable, fully recyclable, domestically manufactured energy storage for critical infrastructure and the grid.
Verdigris
Verdigris is a Mountain View-based AI and IoT company that turns raw electrical data into actionable intelligence for data centers, commercial buildings, and industrial facilities. By clamping high-frequency sensors onto electrical circuits and running proprietary AI algorithms on the resulting waveform data, Verdigris gives facility operators real-time visibility into energy consumption, power quality, and equipment health - detecting failures before they happen, recovering stranded capacity, and driving 20-50% reductions in energy spend. Founded in 2011, the company serves Fortune 500 customers including T-Mobile, Verizon, and NVIDIA across 17 countries.
