Solution

Solution Solar powered tricycle. Kenya has a lot of sunshine all year, therefore we can use the sunshine to motivate some transportation tool to move. The purpose of Solar-powered tricycle can help transport water and some stuffs together. We choose a three wheels vehicle because three wheeler seems more stable and will carry more things. The vehicle do not use gas, its electricity comes from pure solar energy. It carries a big solar panel on the back of the tricycle. When the user pedals on this tricycle pedal, the solar panel receive sunlight and store energy in a battery, the electricity created by the battery will keep the tricycle forward. The solar panels need to be as large as possible to maximize the available sunshinerefrdsfds, but we should be also make sure the voltage is suitable for the battery. HERE IS THE VIDEO WHICH INTRODUCT MORE DETAILS about the theory of this solar powered stuff. Here is our picture of the tricycle. There is a big box at the back of the tricycle, this box can help the person who ride this tricycle to carry some stuffs such as some clothes or some medicine maybe. On the top of the box, the solar panel locates as the lid of the bamboo made- box. The wheels are not the normal wheels we see because these three wheels are not only the wheels of the tricycle, but play the role of water container. The wheels are made of plastics.Because of the power produced by the heavy water, it seems very difficult to make these wheels to move on. So we will put some small gears around the whole circle of the wheels or the water contains, therefore friction between the wheel and the floor will be reduced. Basically, the shape of the wheels look like the Q drum, the difference are the one circle rounded gears which help these big three wheels to move.



Some advantages of this tricycle 1) It provides transportation that is environmental friendly, solar energy will not cause any pollution and it maxmize the usibility of the attanchble resources. 2) Save energy, better than use gas or other expensive energies. 3) Low-cost, and low maintenance, once you buy a tricycle, you do not need pay any extra cost. 4) Help the olders to transport things easier 5) Transport water and other stuffs together 6) Charges while work.

Problems 1)The wheel acts as water container may cause the tricycle loosing its balance 2)The material to connect the wheel and gears are hard to decide.
