"somewhere around fiscal year 2025"

Fiscal year in Japan is from April 1st.

Space stuff always has delays.

They have a bunch of intermediate steps to do first (vertical beaming over kilometers distance).

I don't see it happening in 2025.

Appears to be referring to this project: https://www.engadget.com/japan-will-try-to-beam-solar-power-from-space-by-2025-214338244.html

Japan will try to beam solar power from space by 2025 | Engadget

A Japanese public-private partnership will attempt to put orbital solar arrays in space later this decade…

Does it need to be considered a commercial success or would a single Watt transmitted be enough?

@vincentpearce Single transmission is okay made by the Japanese public-private partnership led by Naoki Shinohara or different future leadership

, nothing prior to today.
