Mini generator costs $ 5 for a 13-year-old girl

At a cost of only about 5 USD (110,000 VND) Maanasa Mendu's "Sun leaves" can produce clean energy from the sun, wind, rain .

Mendu, a 13-year-old girl from Ohio, won the contest's highest award for young inventors organized by 3M Discovery Education. Mendu's products are based on the desire to create clean, inexpensive energy from the wind and the sun.

Maanasa Mendu - She won the highest prize at the Young Scienctist Challenge.

The leaves of her sun convinced the judges of Young Scientist Challenge to win the prize of 25,000 USD and the title of the youngest scientist in America. With a cost of only about 5 USD (110,000 VND), Mendu's leaves can produce clean energy from the sun, wind and rain . This product promises to be very suitable for the countries. poor and underdeveloped.

Mendu's exam design.

Mendu was inspired to create this device after visiting some difficult areas of India, where clean water and energy were rare and expensive. After 3 months of enthusiastic instruction by 3M engineers, Mendu's sun leaves were perfectly perfected despite the original idea of ​​wind power exploitation.

Under the guidance of Mr. Margauz Mitera and the inspiration from the plant's photosynthesis system, Mendu devised a system of "solar leaves" to both harness the energy of light and exploit vibrating energy (Rain, wind .) by combining solar panels with piezoelectric materials.

Finished products after 3 months under the guidance of engineers from 3M Group.

After the competition, Mendu shared about the desire to develop prototype to complete the product and put it into mass production in the future.
