As renewable energy becomes a geopolitical tool, Japan looks to recover its technological edge
China’s near-monopoly on the solar-energy market has prompted the U.S. and allies to step up the search for workarounds. Engineers believe they have found one in a type of solar cell that looks and feels like camera film.
…
Invented by Japanese scientist Tsutomu Miyasaka, the cells use minerals forming a crystal structure called perovskite, which can be used in a device to turn the sun’s rays into electricity.
A key element in manufacturing perovskite is iodine. While hardly a resources powerhouse, Japan happens to be the world’s second-largest producer of iodine after Chile, accounting for around a third of global production.
“Look at what China is doing with semiconductors. That’s bullying,” said Miyasaka, referring to Beijing’s export restrictions on the rare elements gallium and germanium used in chips. “With perovskite cells, the components can be made domestically.”
And every magic tech that didn’t become widespread had this phase.
What’s your point?
Complicated technologies take time to become viable to be manufactured at scale and hit the market. This is normal, not a sign of impossibility.
I see the comment above under every single new tech advance post. It’s meaningless imo.
