Name one of the ways people back then stored energy, how does it work?
For thousands of years, people have stored energy by using it to spin wheels called flywheels. Ancient people used basic flywheels to store energy thousands of years before they began using electricity! The process of storing energy in a flywheel starts when energy is used to make the wheel spin, either by pushing on it or by using a motor. As long as the flywheel keeps spinning, the energy that made it spin is stored as kinetic energy. When it’s time to use the stored energy, the spinning flywheel can transfer its energy to something else. Today, we connect flywheels to generators and use the energy they store to produce electricity
What is potential energy?
The energy that is stored in an object or system
How is the little sun lamp?
The Little Sun lamp, a sun-shaped light with a light bulb on one side and a solar panel on the other.
Who does it work?
invented a flashlight that uses the heat of the human hand to power a light bulb. Her flashlight, called the Hollow Flashlight, has a handle made of special tiles and nothing but air inside. The tiles get energy from the human hand and convert it into electrical energy, which powers a light bulb. The Hollow Flashlight doesn’t have a battery, or even an on/off switch—it lights up as soon as the user picks it up
When was the first battery invented?
What is 1800
What is another way?
These systems use two human-made lakes, one located at the top of a hill and one located at the bottom of the hill. The two lakes are connected by a pipe with a turbine at the bottom. When it’s time to store energy, the turbine pumps the water uphill from the lower lake to the upper lake. When it’s time to use some of the energy that’s been stored, water from the upper lake flows downhill through the pipe, turning the turbine as it goes and converting the stored energy into kinetic energy, which can then be converted into electrical or other types of energy
How does it produce light?
Little Sun lamps charge in the sun during the day and provide light at night,
What other possible energy sources can we use?
What is Wind & water
Why weren't batteries too good back then?
It is because batteries contained a liquid that could leak out & they were big & messy
In 2012 how many little sun lamps were made?
What is 200,000
How are the batteries now better?
Today’s batteries are neater and can store much more energy for their size.However, the batteries we need to produce a lot of power still don’t work as well as scientists would like. These batteries can be heavy and expensive, and getting the materials to make them often means digging mines that can harm the environment.
What type of oil is burned?
What is kerosene?
What were one of the most common ways to store energy back then?
One of the most common ways to store energy without using batteries is by converting it to kinetic energy, or motion energy
