- Luke Iseman, a serial inventor and the former director of hardware at Y Combinator, has raised at least $500,000 to launch his sunlight reflection company, Make Sunsets.- Climate scientists who have been involved with solar geoengineering for a long time say the Make Sunsets balloon launches are not going to generate productive research and that the field needs to be governed by an international body.It's controversial because it hasn't been studied comprehensively, and we don't know whether the unintended side effects will be better or worse than the impacts of climate change.He has designed, invented, built and deployed biochar kilns in rural Kenya, a solar-powered wifi-connected garden sensor, and tiny homes made out of shipping containers, among other projects.He is currently living off the grid in Baja, Mexico, on land he bought a couple years ago, where he continues to tinker."
