The Potential

• Water is More Dense than Air

• 1-4 TW untapped energy

• Easy to Predict

The Problem

• Waves Vary

• Electric Generators tend to Work at High Speeds

• Storms

Stream

• Similar to wind, but under water

• Various types

• Axel Turbines

• Crossflow Turbines

• Oscillating deviceswww.hydropower-hydroelectric.com/ wp-content/u...

Location

• Fast streams

• Bays

• Rivers

• Rocky Areas

What About Fish Safety

• Verdant Power Company Study

• No Fish Casualties Found

A Solution?

• Small Scale Hydropower

Small Scale Hydropower

• Little Environmental Impact

• Water Wheels

• Team Work!
