Fossil fuels are dead (and here's why) - Charlie's Diary

Globally, we use roughly 18TW of power on a 24x7 basis. SBPS's big promise is that, unlike ground-based solar, the PV panels are in constant sunlight: there's no night when you're far enough out from the planetary surface. So it can provide base load power, just like nuclear or coal, only without the carbon emissions or long-lived waste products.Some results are removed in response to a notice of local law requirement.
