OBJECTIVE

To find out what is solar batteryTo identify the principal of a boatTo carry out the advantages of a solar

boatTo acknowledge the uses of solar in our

daily lifeTo instill creativity and innovative skills

among our generation

DESIGN INNOVATION

The Body is aero-dynamic

(the body is narrower at the front) Designed to overcome

friction The side of the boat minimizes the body contact to the water for less water friction The hollow space of

the main body to ease the movement of air through the boat

Uses low density material which decreases the mass (light)

PURPOSE

To use solar energy as a source of power for the boat

SPECIFIC OBJECTIVE

Solar panel are connected in series to maximize the usage of power to produce kinetic energy for the boat

HOW DOES SOLAR POWER WORK?

Solar power is the conversion of sunlight into electricity. In a crystal, the bonds [between silicon atoms] are made of electrons that are shared between all of the atoms of the crystal. The light gets absorbed, and one of the electrons that's in one of the bonds gets excited up to a higher energy level and can move around more freely than when it was bound. That electron can then move around the crystal freely, and we can get a current.

THE ARRANGEMENT OF OUR SOLAR PANEL

AERO-DYNAMIC DESIGN

PROPELLER DESIGN

THE SELECTION OF MATERIALS

We use compressed styrofoam as it is lighter in weight

We also use a hard cover plastic to shape the propeller and a small straw to attach it to the motor

Height: 20cmWidth: 18cm

CONCLUSION

Solar can replace the energy of a vehicle that uses petrol to generate electricity
