In the direction of mitigating the worst of Climate Change, stringent green energy targets have been set for India and the world. To meet these targets, the currently technological state of the art will not suffice. There will be a shortfall of green energy, to the tunes of 100s of GWH, by 2030. Additionally, storage is expensive and further adds to costs. Thus, the green energy market is massively underserved. Using the core principles of thermodynamics, we are developing heat engines that move around sun's heat to produce green electricity at scale. We also provision for energy storage, to power homes and industries, even at night!
