Limits RegistryPUBLIC RECORD
Limits RegistryDeveloped by Wavegen (later part of Voith Hydro), LIMPET used an Oscillating Water Column design built into the shoreline: waves force air in and out of a chamber, driving a Wells turbine that spins regardless of airflow direction. Though modest in capacity, LIMPET demonstrated that wave energy conversion could be commercially grid-connected rather than remaining purely experimental, and it operated for over a decade before being decommissioned.

Developed by Wavegen (later part of Voith Hydro), LIMPET used an Oscillating Water Column design built into the shoreline: waves force air in and out of a chamber, driving a Wells turbine that spins regardless of airflow direction. Though modest in capacity, LIMPET demonstrated that wave energy conversion could be commercially grid-connected rather than remaining purely experimental, and it operated for over a decade before being decommissioned.
The Land Installed Marine Powered Energy Transformer (LIMPET) on the Isle of Islay, Scotland, began commercial operation in 2000 with a capacity of 500 kW, becoming the world's first commercial wave power station connected to a national electricity grid.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
