Wind farms break frequently, kill birds, and need to be placed in high-wind areas. Hydro-electric dams are made by creating massive dams and reservoirs in new places (which has its own slew of problems) and cost in the hundreds of millions of dollars. Not to mention maintenance costs.
But with solar cells, anyone can use this technology. Own a home? Put it on your roof! How ‘bout a car? They make those too. It WILL be the power of the future. This technology will enable cheap and efficient production of hydrogen anywhere, from the middle of the desert to right inside your home.
This is excellent progress and I can’t wait until they break the 50% barrier!
