Solar Concrete

• 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]
