1/ For most of my career, I was driven by a single question: What will it take to move humanity beyond Mars, deeper into the solar system, and ultimately toward the stars?
Pursuing that question led me to two conclusions:
• We need deeper physics.
• And we need persistent power.

2/ My work at NASA focused on advanced propulsion concepts, spacetime physics, and the quantum vacuum.
In exploring those questions, we became interested in whether quantum vacuum effects might also represent an engineering opportunity for persistent power generation.

3/ The underlying physics is rooted in the Casimir effect, a quantum phenomenon studied experimentally and theoretically for decades.
Our focus is not rewriting physics.
It is the engineering challenge:
Can these effects be translated into manufacturable semiconductor devices?

4/ Today, Casimir announced a $12M oversubscribed seed round led by Scout Ventures, with participation from Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates.
The funding supports the substantial engineering and manufacturing work still ahead.

5/ Our first-generation device, the 5mm × 5mm MicroSparc chip, is being developed for ultra-low-power applications where battery replacement is difficult, expensive, or operationally limiting:
*embedded sensors
*tire pressure monitoring systems
*wearables
*remote monitoring systems

6/ There is still significant work ahead:
device optimization, reliability testing, packaging, scaling, and manufacturing.
The leap from theoretical physics to manufacturable semiconductor hardware is extraordinarily difficult.
That is the engineering challenge now in front of us. Godspeed Casimir!
