Sure there may be the energy in a single typhoon equivalent to Japan's power usage for 50 years, but how do you store that energy? Sharp bursts of energy just aren't as useful as sustained power generation.
Vertical axis wind turbines are pretty well studied, if less widely deployed compared to HAWTs. Reading the article it isn't clear to me what they propose that is fundamentally new or different from existing technology. There is brief mention of:
> the speed of the blades can be adjusted to ensure they don’t spin out of
control during a storm.
But a VAWT relying on huge torque during a typhoon would still seem to require huge investment into, well, typhoon-proofing. As is always the case with wind power generation, the real issue is energy storage which isn't touched on at all.
The entire article reads like fluff at best and clickbait at worst.
This kinda just feels like a clickbait headline.
