How does Veeky Forums feel about this gravity battery energy?
Gravity Battery
Henry Anderson
Jace Cooper
my dad had this idea once, so it probably doesnt work
Cameron Murphy
What amounts of energy could be stored practically?
Connor Turner
Gravitation potential formula: E = mgh. For 1 tonne weight lifted 10m(~33 feet) it will be: 1000*9.8*10=98000J
so half a laptop battery.
Nathan Allen
So 10 of those could power a single house over a night
Doesn't sound very practical
Mason Adams
It could work, without a doubt. The only problem is that it will never be able to store enough energy
Isaiah Ward
Extremely low energy density/ 10
Rail storage or pumped hydro are better
Grayson Ross
Stop being energy hogs. Use less energy.

>pumped hydro
How does this one work? I thought it would take massive amounts of energy to pump water to any kind of useable height for gravity to pressurize it or to extract energy from its fall, has technology advanced in this respect?
I couldn't imagine setting up any kind of height difference with water by engineering means, after all nearly all hydro we know of is naturally occuring differences in height between bodies of water... we couldn't just pump entire reservoirs of water up many meters and suspend them like that
Nicholas Johnson
wait.... are you saying a laptop battery can lift 1 tone over 10 meters? that's fucking amazing!
