Wave Energy Converter Design for Maximizing Power Take-Off Efficiency
Quick fact
The theoretical maximum efficiency of a wave energy converter is 50%, known as the Budal limit, but most real devices achieve far less because they cannot perfectly match the wave frequency and damping over time.
Why this is interesting
Imagine a buoy bobbing on the ocean—how much of that motion can actually be turned into useful electricity? The answer depends on a surprisingly delicate balance: tune it too loosely and it drifts with the waves; tune it too tightly and it barely moves at all.
