Some problems aren’t just problems; they’re personal. For me, that problem crystallized at a public event in Knoxville, Tennessee. I took my two-year-old daughter to a portable potty, and the moment I opened the door, she recoiled. That look of pure disgust on her face was a gut punch. It sent me right back to my childhood in India.
I grew up seeing the reality of the sanitation crisis. Summer visits to my village meant open fields were the only option. In the cities, you saw the state of public restrooms, the rampant public urination. That porta-potty in Knoxville was just a chemical-laden, plastic version of the same fundamental failure. We haven’t solved the problem; we’ve just found better ways to hide it.
This is the contradiction that drove me: we have the technology for space travel with ambitions to go to Mars, we have 85″ LED TVs for less that $1000, yet nearly half the world lives with a daily, undignified, and dangerous reality when it comes to sanitation.
As an engineer, I’ve dedicated my career to energy and thermochemical conversion. I look at a problem and see systems. I see inputs and outputs. And the current sanitation equation is broken. To be clean, it needs water. To be deployed globally, it must be waterless. To be safe, it can’t use chemicals. To be sustainable, it can’t create waste. To be mass marketable, it has to be cost effective.
For too long, we’ve accepted these as unavoidable trade-offs. It’s time to stop.
The answer comes from a new convergence. For the first time, the tools we need are all within reach: low-cost solar, efficient LFP batteries, and the incredible power of AI to automate and control complex systems. We can finally build something that doesn’t compromise.
That is why I am proud to introduce the concept of The Shunya Toilet.
“Shunya,” in Sanskrit, means zero. It’s a concept that came from India, representing not just a number, but a new beginning. It is the foundation of our design.

- Zero Water: It is completely disconnected from plumbing and water lines.
- Zero Sight, Zero Smell: The user experience is always clean and dignified.
- Zero Chemicals, Zero Waste: It doesn’t mask problems. It converts waste into harmless, natural elements.
- Zero Environmental Impact: It is a self-contained, AI-powered system that generates its own energy from the sun and its own fuel.
- Zero Indignity: It offers a safe, modern, and hygienic solution for anyone, anywhere.
This isn’t just another toilet. It’s a fundamental rethinking of the entire system. It’s a closed loop that respects both the user and the environment, inspired by the way nature operates. In nature, nothing is waste; everything is reused. We are simply using our advanced knowledge of thermochemical conversion to accelerate that natural cycle, using high temperatures to do in minutes what takes nature years.
The full technical details are something I look forward to sharing soon. For now, I wanted to share the vision, the promise of starting at zero to finally solve one of humanity’s oldest and most pressing challenges.

The time for compromise is over. The time for Shunya is now.

Curious to understand its mass and energy balance, odor balance as well.
