David Bombal #543: Why We Are Drowning Servers in OIL
Feb 20, 2026
Denise Lee, an industry executive focused on data center power and cooling innovations, explores why modern facilities waste so much energy. She discusses fault‑managed DC power, immersion cooling that baths servers in oil, and how these shifts cut waste and change required skills. Short, technical, and future‑facing conversation about sustainability and new career opportunities.

Episode notes
Adopt DC And Fault-Managed Power
- Adopt DC-native and distributed power architectures to improve efficiency and reduce dependency on long AC distribution.
- Use fault-managed power (Class 4) to safely deliver high-wattage DC over touch-safe cabling up to 450 VDC.
PoE Paradigm Applies To DC Power
- Fault-managed DC can be distributed over cables similar to PoE and remain touch-safe while supporting high voltages.
- This creates parallels to past shifts where networking absorbed telephony roles and enables new installer skills.
Train Network Teams For New Power Work
- Upskill networking and limited-energy electricians to install fault-managed DC cabling safely.
- Empower network engineers to deploy these systems since the cabling practices mirror PoE installations.
