This candidate for the "free energy woo-woo of the year award" clams that get energy from gravity with a efficiency of 80%. |O

At first I misread that as 800% and I suspected Batterisers were involved. ;D

Lighthouses used to have "gravity energy storage" devices to rotate the light. ;D
There was a big weight on a chain which slowly "fell" from near the top of the lighthouse tower to the bottom.
Every few days, the Lighthouse keeper would wind it up with a big "crank handle".

Don't hydroelectric power plants regularly achieve 90-95% efficiency?

I watched the video and I'm only the second thumbs down, can anyone "help" with this?

That Gravity Energy © proof of principle 2016 video with the balancing weight reminds me of that box shimmering on its own in The EEVblog Lab VIBRATES! video.

I don't think you can get any energy out of that.

The last picture on their homepage explains how it works: we need an elephant (not included) to make it vibrate.

Apparently, these guys reinvented the wheel one of these pseudo perpetual motion toys (https://en.wikipedia.org/wiki/Perpetual_motion#Apparent_perpetual_motion_machines) like "drinking bird" or barometric clock.
P.S. "Fake? No, sir. There was two dollars' worth of fluid extract of cinchona and a dime's worth of aniline in that half-gross of bitters. I've gone through towns years afterwards and had folks ask for 'em again."(q)Jeff Peters as a Personal Magnet.

Not certain but I think they are just using gravity to store energy in what looks like an inverted pendulum. This is nothing new. An ordinary pendulum cycles energy between kinetic and potential with every half cycle. Large scale energy storage by pumping water up and letting it fall through a hydro plant is another example.
