Renewable Energy × African Mining Solar (Hybrid Power)

killed: Samsung and Nosh Robotics integrating cameras into kitchen hardware (CES 2026). Low willingness to pay for cooking apps (industry precedent: free). Declining cooking frequency among target demographic. Decreasing need for guidance as users learn (retention cliff).

killed: The Sense Home Energy Monitor and Google Nest already provide appliance-level consumption insights to millions of homes via hardware and platform integration. Utility-side analytics platforms (Oracle Utilities, Itron) serve the B2B market. The Green Button API dependency limits reach to approximately 60% of U.S. utilities, and the incumbents already hold the integrations, brand trust, and hardware relationships needed to serve both consumer and enterprise segments.

killed: Prepaid energy customers are cost-constrained by definition, limiting willingness to pay for a subscription optimization tool, while the utilities themselves hold both the granular consumption data and the regulatory incentive to offer budget management features directly — eliminating the business model for any independent software layer between the meter and the household.
