> 
> Abstract  
> Erlang was designed for fault tolerance, not fitting into tiny memory footprints on energy-starved embedded systems. But what happens when you push it into just 16MB of RAM, run it on an RTEMS real-time OS, and power it from temperature gradient energy harvesting?
> 
> In this talk, we’ll dive into the challenges and solutions of making the full Erlang runtime, OTP, a TCP/IP stack, and USB support work under extreme constraints. We’ll explore the brutal trade-offs in memory usage, optimizing the boot process for minimal energy consumption, and the unexpected quirks of running Erlang on hardware where every millijoule counts.
> 
> Along the way, we’ll break down how GRiSP nano boots from a cold start, how energy availability affects system initialization, and what we learned from pushing BEAM into places it was never meant to go.
> 
> If you’re curious about embedded Erlang, extreme resource constraints, or just want to see how far you can push the runtime, this talk is for you.
