Well, here we are at the end of 2025. I thought I would give you all a quick update on what is happening at Gravitec Inc. and its SFE Propellantless Propulsion Research. So, while working through the holiday season has posed a challenge, I have managed to continue making progress on our new SFE Propellanltess Propulsion Device technology base. The current research required almost a complete retooling of the technology base, which posed some challenges that have now been overc

Volvo No Cab Robot-truck Autonomous trucking is steadily moving from pilot projects to real commercial operations. As that happens, one question keeps coming up: Will AI-driven trucks actually be safer and more productive than human drivers? Growing evidence suggests the answer is yes , provided the technology is deployed responsibly and within clear regulatory frameworks. Below is a data-backed case for why autonomous trucking is positioned to outperform traditional fleets,

Why LEO can’t support infinite satellite growth—and what the numbers are already telling us. Low Earth orbit (LEO) is often spoken about as if it were an open frontier: big enough to absorb endless new satellites, forever. But LEO is not an infinite resource. It’s a finite, shared operating environment  with hard physical constraints (orbital mechanics and atmospheric drag), operational constraints (tracking and maneuvering capacity), and environmental constraints (debris per

So yesterday I had published in LinkedIn an argument for why Space Based AI Data Centers were a bad idea. Today, I decided to publish another article on what I see as a viable alternative to the Space Based Data Centers. You can read the article by following the link below. https://www.linkedin.com/pulse/space-underwater-practical-path-ai-data-centers-hector-serrano-sshze/?trackingId=mKc8ydJx8Lnrpk4y3Juc9w%3D%3D I basically argue for placing AI Data Centers Offshore and power

I wrote a document titled “Why Space-Based Data Centers Do Not Scale.” The article, published on LinkedIn and available at the link below, outlines what I see as the major problems with the idea of moving AI data centers into orbit: https://lnkd.in/e3jmVWKP It seems to me that many people are blindly following this idea without giving serious thought to whether it is actually viable or, if it is, why it would make sense. It took only seconds for me to recognize that a concept

Hello everyone. So I wanted to give you all a quick update on what is happening at Gravitec Inc. As you may or may not know, currently I'm working on what I'm calling the Second Generation SFE Propellantless Propulsion Thruster (Space Drive). If you have never seen our first generation thruster technology, you can click on the link below and it will take you to our patent. https://patents.google.com/patent/US6492784B1/en?assignee=gravitec&oq=gravitec+inc This generation of Pr
