Electrical Output

BLUE MOTION ENERGY SYSTEM – FINAL CALCULATIONS

SINGLE DOCK UNIT (Blue Motion Generator)
Floating Concrete Dock weight:
12,000 lbs = 5,443 kg


Stroke height: 6 inches = 0.1524 m


Cycle rate: 10 full up/down cycles per minute = 600/hour


System efficiency: 80%


Energy harvested on both up and down strokes


Step-by-step:
Potential energy (1 stroke):
PE = m × g × h = 5,443 × 9.81 × 0.1524 = 8,143 Joules


Full cycle (up + down):
2 × 8,143 = 16,286 Joules


Energy per hour (600 cycles):
16,286 × 600 = 9,771,600 Joules/hour


Convert to kWh:
9,771,600 ÷ 3,600,000 = 2.714 kWh/hour (mechanical)


Apply 80% efficiency:
2.714 × 0.80 = 2.17 kWh/hour (electrical)

 

MARINA WITH 100 PILE SLIPS
Monthly electric bill: $11,200


Electricity rate: $0.20 per kWh


Calculations:
Monthly energy usage:

11,200 ÷ 0.20 = 56,000 kWh/month


Hourly energy usage (assuming 720 hours/month):
56,000 ÷ 720 = 77.8 kWh/hour

 

BLUE MOTION SYSTEM WITH 36 DOCK UNITS
Energy per unit: 2.17 kWh/hour


Total with 36 units:
2.17 × 36 = 78.1 kWh/hour

 

FINAL SUMMARY
Each Blue Motion unit generates: 2.17 kWh/hour


The marina uses: 77.8 kWh/hour


36 Blue Motion units produce: 78.1 kWh/hour


Result: 36 units can fully power the marina’s hourly energy needs saving marinas thousands monthly in electricity
