This week on New Wave Weekly: change is no longer a scientific forecast.

👉 Fusion Energy: Is It Around The Corner?

Proxima Fusion raises $200M, U.S. players pull in mega-rounds up to $900M… and suddenly everyone’s bullish. But is fusion coming in 2030, or 2100? Game-changing tech or just another beautiful mirage?

👉 The capital stack goes creative

Grants, debt, PPAs, infra equity, climate finance is finally evolving beyond pure VC. But who’s funding $100M FOAK projects? And where are all the climate-native CFOs?

👉 OpenAI x Oracle, $300B and 4.5 GW

One AI deal = 4 nuclear reactors. As data centers suck up grid capacity, could the compute boom drag climate tech into the fast lane?
