Engineering Evaluation & Certification Objective

​

As targeted strikes continue to compromise the centralized energy grid, survival depends on localized, hyper-efficient, non-electric thermal systems. The Defiant Heat designs comprise specialized biomass heating systems especially adaptable to repurposing war debris and using readily avalable local materials to create high-efficiency, pollutant-free, radiant heat.

 

We are seeking formal academic and engineering evaluation to analyze, validate, and certify the thermal efficiency, draft mechanics, and structural safety parameters of this design for emergency deployment in vulnerable communities. The basic design is also capable of meeting building code standads for safffe, insurable home heating in America.

#1 Introduce New Heat to Ukraine

DefiantHeatDetailedPlans_edited.jpg

Three years in the making, we finally began building these J-Tube designed systems in Kharkiv , December 2025. This is the heart of the modern rocket heating designs. In recent years, ceramic fiberboard has replaced traditional brick to provide a very lightweight adaptable heating core that is also portable.
