What I also find very interesting are the "tuned column liquid dampers", which applies the same idea of "tuning" the period of the liquid system to one period of the structure. They are found to be very effective in dissipating energy after seismic events or constant wind. I'm a civil engineering student (currently writing my thesis) and I just loved this systems when I learned from them.
