Vikram interviews Doug Krause, president and founder of RUTE SunTracker, for a wide-ranging conversation on the future of utility-scale solar. Doug traces his path from commercial fishing in Alaska and tensile-membrane cable work across Europe to mechanical engineering and solar project finance, and explains how that mix led to RUTE's patented cable-based mounting system, the same structural principle used in suspension bridges and ship rigging, applied to PV.

They dig into "cattle solar": elevated panels four metres above pasture that give ranchers free shade, cooler cows, more grass and retained water, while the operator gains bifacial yield and lower land and vegetation-management costs. The discussion ranges across LCOE and why Doug believes cattle solar can be the cheapest way to build, the UK "developer bloodbath" and spam grid applications, cable-factory and high-voltage connection bottlenecks, Texas and ERCOT, GIS and how little land solar actually needs, and how RUTE's "fields" and "blooms" turn EPC crews into riggers with no pile-driving or trenching.
