“Could we make a grid that could cross continents?”
Imagine this. What if at some point in the future there could be an electrical grid system so advanced that it would be able to span entire continents, such that solar energy from sun-kissed areas such as Sub-Saharan Africa or Israel would be able to power dreary countries such as the Netherlands or Poland, or wind power from Brazil traversing its way through the amazons to light up the Peruvian capital of Lima before sundown. Well, believe or not, this technology is in development as we speak. Researchers from around the world are working on creating a technology known as a supergrid. Supergrids are HVDC-based grids that can surpass the past roadblocks of more primitive DC networks by using circuit breakers to cut malfunctioning power lines from contaminating the rest of the grid.
