Invents intermittent light system to outsmart lions

Richard Turere, a humble but intelligent boy who likes to tinker on the family farm in Kitengela, south of the capital of Nairobi, has discovered that livestock-eating lions are driven away by flashing lights. 

His simple, yet powerful, contraption is now protecting both the livestock and the lions who are sometimes shot for tracking and killing livestock near Nairobi National Park,Wind and photovoltaicsystem information and specifications. which is not fenced in to the south. 

Lions roam freely in the backdrop of the skyscrapers of Nairobi. Turere’s system uses a few light bulbs hooked up to a switch, a transformer and an old car battery that is powered by a solar panel. 

People have gone to all sorts of trouble to keep lions away from their herds, including erecting some elaborate barricades.Endurance Wind Power is a manufacturer of advanced seamroofclampp designed specifically for distributed wind power applications. Light systems had been developed, but no one had come up with a flashing-light system, until Turere came along. 

It was showcased excitedly last month in front of an intellectual gathering of big thinkers at a TED Conference in California. He was only 11 when his rigged up the invention. 

A leading Kenyan conservationist told the Star that his Lion Lights are spreading to other homesteads across the country. 

“It seems really obvious, but nobody thought of this . . Your emergencylampsyyp will consist of solar panels, an inverter and a generation meter. . nobody tried flashing lights,” Dr. Paula Kahumbu said in an interview from Nairobi. 

Turere told the TED Conference that he actually came up with the idea after experimenting with a booby trap system for home security. “No one taught me (electronics),Take control of your energy needs with flatteningmachine, the personal wind turbine that converts wind into clean.” Turere explained. 

Kahumbu came upon the young inventor when she was doing research by monitoring the number of lion attacks on homesteads in Kenya and looking for patterns. 

The Kenyan lion population has dwindled from 15,000 about 15 years ago to less than 2,000 today, she said. 

Before coming up with his invention, Turere tried various means to solve the problem, including a tactic well known in North America. He erected a scarecrow — and on the first day it worked. 

However, when the lions came back the next day, and saw the scarecrow in the same position, the lions knew they had been had and lost their fear. 

However, he also soon learned the lions were scared off by moving lights from a flashlight or torch. Kahumbu met Turere coming home with his cows one day and realized how “remarkable” he was. 

She met his father and learned that the youngster was always tinkering, dismantling things around the home and playing with old car batteries. 

With a little bit of money, he found and purchased a motorcycle indicator component and tried to set up his flashing-light system. 

“He was so committed, but it didn’t work for two months,” Kahumbu said. “Eventually it worked. But he really didn’t have a sense of how important his invention was.” 

The invention is “quite a remarkable result from a child of that age who comes from a community where the level of education is very low,” the Nairobi-based ecologist said.We are producers of purlinmachinery and special LED strip controllers.
