- Embodied energy of concrete - 5.6 MJ/kg. Note that pure cement is only 1 MJ/kG
- 1 MJ = 0.3 kWhr (1 kWhr = 3.6 MJ)
- Thus, a 10 kW solar panel array, affordable by any University Solar Concrete Project - pr donated for conscience - has 60kW hrs of energy per day
- Concrete block is only 10-15% cement
- 1 kWhr gets us .6 kg of cement
- 60 kW gets us 36 kg of cement!
- 8x8x16" cinder blocks [1] are 30 lb or 15 kg
- Concrete block - [2]
- 1:3:6 cement for concrete blocks - [3]
- We can make 36 kg of cement per day with a 10 kW array, or 360 kg of block - or 24 block per day.
- Standard concrete blocks are $1.40 each - [4]
