The hard part is not the invention
Clean energy is a hardware business pretending, in public, to be an ideas business. The device that works in a laboratory is rarely the constraint; the plant that makes ten thousand of them a week, the queue position that lets them export power, and the process engineering that removes a step from the line are. These essays are about that side of it — manufacturing scale-up, grid connection, storage sizing, and where cost reductions actually come from.

- Cost Curves Are Built, Not Discovered
The decline in clean energy hardware costs is an accumulation of process engineering — material removal, step elimination, throughput, yield, standardisation — not a sequence of breakthroughs. Which is why some technologies learn quickly and others never do.
- Duration Is Not Power
A storage asset has two independent ratings and they are bought from different suppliers. Why the split between megawatts and megawatt-hours decides which services an installation can sell, and which it only appears to.
- Everything Waits for the Interconnection
Why connecting a finished generator to the grid takes longer than building it — the sequential study problem, speculative queue entries, upgrade cost allocation, and the withdrawal cascades they produce.
- The Factory Is the Technology
A working device and a manufacturable product are separate inventions, and the second one takes longer. Why scale-up, not discovery, is where clean energy hardware actually gets stuck.
