The Homo erectus discovered it more than 1.4 million years ago. Fire is a set of incandescent particles or molecules of combustible matter, capable of emitting heat and light. -
It was invented by Thales de Milato to attract iron objects. The magnet is a body or device with significant magnetism, such that it attracts magnets or ferromagnetic metals. -
It was invented by the Chinese around 1200. Gunpowder is a deflagrant mixture used mainly to propel projectiles in firearms, and for acoustic and visual purposes in pyrotechnic displays. -
Benjamin Franklin began his experiments on electricity. Electricity is the set of physical phenomena related to the presence and flow of electrical charges. -
Alessandro Volta invented it to obtain electrical energy. Is a device consisting of two or more electrochemical cells with external connectors, cells that convert stored chemical energy into electrical current . -
It was invented by Edwin Drake to be used as fuel. It is a product obtained from petroleum by distillation. -
It was invented by Thomas Edison, after purchasing the patent from Woodward and Evans. The light bulb is a source that produces artificial light. -
Charles Fritts invented it in 1883, they invented it to absorb sunlight and convert it into energy. It is a rectangular structure with a basic transformation unit that is the solar cell and measures approx. 10 cm square. A panel joins several of these cells on a plate, which are covered with a plastic called EVA. -
Charles Francis Brush invented it, he invented it to exchange momentum with the wind. A wind turbine or wind turbine is a turbine powered by wind energy. It is a turbomachine that exchanges momentum with the wind, turning a rotor. -

it was invented by Lisa Meitner.Fission is the division of a nucleus into lighter nuclei, plus some byproducts such as free neutrons, photons and other fragments of the nucleus such as alpha and beta particles, as well as a large amount of energy. -
It was invented by Percy Spencer when he was researching how to improve the performance of radar. The microwave oven is an appliance used in the kitchen to cook or heat food that works by generating electromagnetic waves at the frequency of radiation. -
They were created by Julio De La Cruz Blázquez. Tidal current generators, also called TSGs, use the kinetic energy of constantly moving water. In this case, the turbine propellers rotate, transferring the tidal energy to a generator that transforms it into electricity.
