The Download: a “God-driven” cryptocurrency and a solar engineering roadmap

Eli and Kaitlyn Regalado launched INDXcoin after claiming divine instruction, raising over $3 million from more than 500 investors before the project collapsed within a year, leaving investors with total losses and prompting fraud investigations. Reflective, a San Francisco nonprofit, released a comprehensive roadmap outlining the experiments, studies, and infrastructure required to evaluate solar geoengineering’s climate-cooling potential and associated risks. Vaire Computing’s CTO Hannah Earley demonstrated a reversible-computing chip that recovers more energy than it dissipates, offering a path toward substantially more efficient data-center and consumer-device power use.
