Light Bulb Powered by Human

At Only 15 Years Old, She Invented a Virtually Inexhaustible Source Of Light

Light Bulb Powered by Human

After batteries powered by solar energy, wind power or terrestrial heat, here are the batteries powered by inexhaustible energy … The heat of the human body! A 15-year-old Canadian has invented a revolutionary light that works with this energy.

Ann Makosinski only 15 years old and all the press talks about it. It must be said that what she invented is very interesting. The girl was selected from a host of candidates to participate in the final of the 2013 edition (for 15-16 years) of the  Google Science Fair, an inventions competition organized by the Mountain View company. A scientific convention that takes place every year and allows to discover and promote the talents of tomorrow among young people motivated and inventive. Ann Makosinski its part has invented a revolutionary object: a flashlight powered only by body heat of the palm of the hand.

Called Hallow Flashlight. With LED bulbs from ledbulbbay, this flashlight works using the principle of the Peltier effect. It is a physical principle that one can create energy by using the displacements of heat on conductive pieces of metal. Thus, she explained” There are several pairs of these two metals sandwiched between two ceramic plates. As the part of the hottest hand is the palm, that’s where I decided to concentrate the system. It is very simple: you just have to place the palm of your hand against these plates and it lights up.”

She also explains that she began experimenting with this technique at the age of ten, after participating in several inventions competitions. The Hollow Flashlight can stay on for at least 20 minutes with the heat of your hand. Ann says she has yet to test beyond this period. Even if its plans for the future are not yet fully defined, it is clear enough to patent its invention and eventually find a way to commercialize it.

Meanwhile, she will visit on September 21 in the premises of Google whether or not win this edition of the Google Science Fair. The winner will receive a very special prize since his schooling will be supported entirely up to $ 50,000 (€ 37,585) and a trip to the Galapagos Islands. If you want to encourage Ann or watch what the 15 other inventors have proposed, you can go to the  website dedicated to this contest;).

It is an extraordinary invention and we would like to hold it in the palm of our hand to see how it works with our own eyes. It’s crazy to realize that such young geniuses can rival inventiveness and rigor with their elders to design such objects. Do you imagine a company where all the devices could be fueled by the beating of your heart?

The most “incredible” is that the manufacturers of flashlights were careful not to manufacture this type of torch, while they knew perfectly the effects Peltier and Seebeck and their applications. Wikipedia testifies … << This makes it possible to make an electric battery powered by a very low heat source (such as human body heat), but enough to light a flashlight. >>. I suspect rather the industrialists of having wanted to sell us lamps and batteries very useless! … (In addition to the programmed obsolescence of their flashlights that do not last longer than the recharging of two batteries given the Very poor quality of the latest products put on the market) It is far from time for the strength of the MAZDA lamps. The lamps have become disposable da ns total disrespect of the consumer and the environment and I would not be surprised to learn later that the patent that this girl wants to file already has a history held by one of these manufacturers Lamps or batteries … As we already know how these crooks have made to shorten the life span of the filaments of the light bulbs in order to sell more! … The question that comes to my mind Is whether this system was already used by the Egyptians when building inside the pyramids, because a torch system was discovered from that time but still unexplained to this day?
