817: Turn Your Roof into a Money Machine: How to make as much as $32/Hour with Solar + AI Compute power! | Karl Andersen of Lektra

Published on: 23rd May, 2025

What if your rooftop solar could do more than just power your fridge?

Karl Andersen believes it can—and should—power the future of AI.

Karl unpacks the grid’s biggest vulnerabilities, why data centers lack critical power infrastructure, and how we can turn solar-powered homes into the building blocks of a decentralized compute network. Lektra’s tech fuses distributed energy with cloud computing—think “Raspberry Pi meets Tesla Powerwall meets AI.” The result? A game-changing business model where solar homeowners become micro data centers—and start earning like one.

From national security concerns to GPU monetization, Karl walks us through why our energy and data systems are broken—and how his patented solution bridges both.

Expect to learn:

🔹 How Lektra turns excess solar energy into compute power

🔹 Why grid fragility is now a national security issue

🔹 What it takes to patent an entirely new category of energy-tech

🔹 How homeowners could earn 1000x more than selling to the grid

This isn’t really even about solar. It’s about rethinking energy, ownership, and what the next version of the internet could look like.
