Maybe the coolest idea that I've heard of in years is the business model of this company.
One of the major downsides of renewable energy sources like solar or wind is that you don't have the same amount of energy being constantly produced over an interval of even one day. So you will need to somehow store that energy in order for it to be available at night or when there is no wind blowing in the turbines, but batteries are extremely expensive and pollute a lot in their production.
As an alternative to storing energy into batteries, Energy Vault is lifting heavy blocks of material with surplus energy available and when there is a demand of energy it brings those blocks down in exchange for that energy. Basically it is converting the electrical energy into potential energy based on one of our basic and still not understood forces: gravity.
Innovations like this one, even as simple as this are required to enable our transition to a green future with very low carbon emissions.
Thanks for reading and take care of this planet!
Something better should indeed be invented. The USA should invest much more money into this (energy storing) segment of the industry, instead of putting a lot of money into various wars and battles, and into other similar things.
I am sure that if they would have been put that money into researching and development over the last few decades, then we would already have a much better energy storing technology.
I give you some !PIZZA.
Have a nice day. All the best. Greetings from Hungary.
Thanks for the !PIZZA. I don't understand yet how this works :D
Yes, I totally agree. I think we as human kind have just started to grasp the importance of taking care of the environment.
@mejustandrew, sorry! You need more to stake more $PIZZA to use this command.
The minimum requirement is 20.0 PIZZA staked.
More $PIZZA is available from Hive-Engine or Tribaldex
