Novel Solar Powered Lawn Mower

Haritha Yearuva

The reliance on non-renewable energy sources such as gasoline, coal and natural gas has resulted to global warming and steady increase of prices on these commodities. Due to the increase in earth atmospheric temperature the weather around the world is changing adversely resulting mankind to transform their lifestyle to be more energy efficient. To address just one aspect of the above problem; the proposed research deals with designing of a traditional gas powered lawn mower into a green lawn mower, which will be powered by solar energy. The suggested solar powered lawn mower utilizes ample amount of solar energy available from the environment to run the electric motor that in turn cuts the grass. We present a novel approach of utilizing low weight and high power components such as AC motor and electrical circuitry required to build the solar powered lawn mower is going to be discussed. The 116 watt will be moved by solar cell panels installed on the machine in a sunny day and by 80ah batteries on board of the mower if the day is cloudy.
