LENR
LENR is one of two technologies projected for 2026-2027 commercial deployment.
01 Definition
Low Energy Nuclear Reactions. Nuclear reactions occurring at or near room temperature, producing excess heat. Also called 'cold fusion' (stigmatized after 1989 Fleischmann-Pons). Validated by SRI International for Brillouin Energy.
02 Detailed_Analysis
LENR produces thermal energy from low-energy nuclear reactions. SRI validated Brillouin's technology with COPs of 1.2X-1.45X and 'very high confidence' of excess heat.
03 Key_Facts
- ▸ Also called 'cold fusion'
- ▸ SRI validated with COPs 1.2X-1.45X
- ▸ ARPA-E held official workshop (2021)
- ▸ DOE imposed 7 secrecy orders (FY2023)
