Kardashev Won: Cooling the Planet With Zero-Fuel Power

What if the "waste" heat pouring out of factories could power those same factories and help cool the planet at the same time? In this episode, host Dan Jacobs sits down with serial founder and renewable-energy innovator Johannes Jacobs, founder of Kardashev Won, to explore how advanced Organic Rankine Cycle (ORC) generators can turn industrial waste heat into reliable, on-site electricity.

You’ll hear how Kardashev Won is building zero-fuel, closed-loop power systems that:

• Harvest waste heat from large industrial and commercial sites to co-generate clean electricity 24/7, 365 days a year.

• Aim for a "moonshot" of pulling excess heat directly from the atmosphere using highly efficient heat pumps combined with ORC technology.

• Deliver rapid ROI by cutting energy bills while reducing emissions and pressure on the grid.

Johannes shares the engineer’s view from inside his enormous "mad scientist" workshop, where he is constantly experimenting, testing, and filming the development of next-generation turbines, heat pumps, and ORC systems. He explains how small, compounding efficiency gains across dozens of components can combine into game-changing performance, much like compound interest for energy.

But this conversation goes far beyond the tech. You’ll also learn:

• How he built and exited multiple service businesses in solar, plumbing, and electrical work over three decades.

• Why "efficiency first" can cut a customer’s electricity use by up to 80% before you add a single solar panel, and why competing on quality beats competing on price.

• The simple hiring and culture principles he used to build high-performing crews: attract upwardly mobile people, over-equip them with the right tools, and then get out of their way.

• How obsessing over customer experience (from tidy worksites to a "happy letter" sign-off) creates trust, referrals, and a pipeline built almost entirely on repeat business.

If you care about industrial decarbonisation, waste-heat recovery, energy efficiency, or how to design a resilient, quality-led service business, this episode is for you.

Listen in to discover how Kardashev Won plans to become a planetary-scale heat pump for industry, turning today’s waste into tomorrow’s power.
