🔋 A Houston startup working on a chip that generates power without charging just landed an Air Force contract.
🧪 Casimir was founded by physicist and engineer Harold "Sonny" White, formerly of Johnson Space Center
🚀 He launched it through Limitless Space Institute, a Houston nonprofit co-founded by Kam Ghaffarian
⚛️ The tech captures electricity using the Casimir effect inside microscopic cavities, layered together to power devices for long stretches without degrading like a normal battery
💡 First chip, the MicroSparc, is targeted for 2028 at 1.5 watts, roughly a small rechargeable battery
🎖️ The Air Force Research Laboratory and SpaceWERX want something bigger: a 1-kilowatt solid-state generator White describes as a "Lego brick"
🏫 Submitted with Texas A&M, since the STTR program requires a research partner
💵 Dollar amount wasn't disclosed. Phase I contracts are typically several hundred thousand
The bigger picture: Casimir is one of nearly 100 Houston companies to receive an SBIR or STTR grant in the program's history, and 37 Houston companies got at least one last year. Other local names in that pool include Venus Aerospace, March Biosciences, and Helix Earth Technology.
White's take is that an early government contract is both money and a signal. He also notes companies can need 30 attempts before one lands.
If you had a power source that lasted for years, what would you put it in?
