You have been asked to finance the US R&D for advanced hydropower technology for reducing the impact of current installations on fish migration and on developing economically and technically viable low-head, run-of-river technologies by allocating a portion of the current revenues generated from electricity sales from hydro resources. Estimate the revenue stream that! would be produced annually as a function of the "sustainable R&D trust fun surcharge" amount in cents/kWh. You can assume that the average generating base price for hydropower in the US is $0.03/kWh
