- 1 cubic meter of concrete weighs 2400 kg
- MGH - energy if taken up to 100 meters with a crane
- Common cranes are 80m max and 20ton capacity - [1]
- Take 30 meters tall and 2.5 ton capacity (practical village scale). Can double up as an observatory or sky diner on top.
- Take 2.5 ton weights - about a cubic meter
- One 2.5 ton weight raised 30 meters - takes MGH=2500*10*30=750,000 joules=750k watt-seconds
- 750kWs=20 kW minutes = 0.3 kWhr
- Not bad.
- Take 30 such blocks - about 30 meters tall - one column - and energy in there is 30*2500*10*15 - with 15 average height raise.
- That is 4.5 kWhr
- To make this practical - would need many such towers. Geometry, stabilization, handling are the keys - how to achieve a sound design?
- In principle sounds like a great idea, if the automation and CV AI can help
- For much smaller scale - say 10 meters tall and blocks of 2 tons - take 100 blocks -
- $100/cu yd of concrete - bioconcrete or burned limestone could be a trick here.
