Advantages of Floating Turbine

Accessible for everyone Easy to build Does not require high costs Durability Is not limited by the width of

the river Easy to install

Climate Changes

Ecology• Combustion of coal C+O2 CO2

• Combustion of natural gas: C H4+2O2 CO2+2H2O

With floating turbine we save environment from• Washing off animals’ nests• Affecting life-cycle of fish• Obstructing fish migration• Creating potential danger of plant failures• Changing climate in the given area

Ecology

• We investigated ways of hydro and solar energy assimilation

• We studied impacts on ecology causes by these power productions

• We created two models of environmentally friendly energy collectors

• After carrying out experiments we improved our modelsand built large ones

Conclusion

Floating Turbine Green Heating

Cheap Clean & Easy

THANK YOU FOR YOUR ATTENTION!
