Sounds flashy, but the heat you’re buying from a bio‑fuel reactor still comes with a carbon budget and a lot of logistics. You need to be sure the feedstock comes from truly renewable sources, that the combustion is ultra‑clean, and that the reactor doesn’t become a fire hazard for the whole building. Solar panels might have a higher upfront energy debt, but they’re passive, don’t need continuous fuel, and their waste is minimal. Before you trade one green problem for another, map out the emissions, the water use, and the safety margins. If it all lines up, it could be a neat hybrid, but right now it feels more like a “cool” idea than a truly cleaner replacement.
