| Abstract Scope |
About ~ 2/3rd of the available fossil energy is globally wasted as mostly low-grade heat (<80°C). Thermoelectric generators (TEGs) can directly convert it into electricity and thus counter the climate change crisis. However, several commercial and engineering challenges such as presence of toxic, expensive, scarce elements in efficient thermoelectric (TE) materials; commercial and engineering constraints in designing TEG modules, etc. limit their sustainable and scalable application. Herein, we propose using carbogels for large-scale TE application through their electrical functionalization. Employing pyrolysis treatment of commercial xerogels followed by carbon fiber insertion, we first demonstrate an 11 orders of magnitude increment of the TE figure-of-merit (ZT). A TEG in the form of a vacuum insulation panel was then fabricated for self-powered vacuum-failure detection application in automobiles. Finally, by extrapolating optimized output power and CAD-assisted assembling of a large TE module (100 cm2), the potential of scalable ambient waste heat recovery is discussed. |
