What a clickbait title. It has nothing to do with physics or science. The guy happened to be a physicist, and was in charge of building renewable energy. So he took out loans to finance the project. Saved you the wasted time reading this.
He didn’t take out loans. He offered guaranteed rates to international private companies say they would finance the infrastructure instead.
It still has nothing to do with physics or science. I don't care to read about financial instruments when the title implies some sort of scientific breakthrough.
The code was convincing renewable energy companies to finance the upfront cost of building renewables. It's pretty much just seeking loans in a way that doesn't inflate their national debt.
