Future energy

The faucet kept flowing out of the clear tap water, but the people who used the water didn't know it; when the electric light was turned on, the TV room was empty for a long time; the notebook was thrown into the trash can, but only a few pages... Natural resources It is limited. Mother Earth gives us abundant resources unselfishly. However, our children and grandchildren are not temperately mined. Sooner or later, there will be little resources left on the ball.

Scientists have long guessed that they have used their wisdom to create magical energy.

In the 3,000 years of the park, the resources on the earth are gone, there is no electricity, no water, no trees, no minerals, and the earth is empty. The industrious scientists revived the earth according to the wisdom of their predecessors.

I don't want to see quarrels and wars in the world. I hope that the world is full of joy and peace. So I am imagining how good it is for each household to have a “micro-energy device”. This energy device does not require us to destroy underground resources, and can absorb all natural energy sources such as solar energy and wind energy at any time.

They collected the summer sun and hid it underground. After three months of solidification, they formed ice cubes---thermal crystals. It is made up of sunlight, a basement that can be used by the city for 3 months. Throwing this crystal into the water, the cold water immediately turns into warm water; throwing the crystal into the jar and immediately turning it into an electric light; throwing the crystal on the open ground, the cold winter will be very warm...

3000 AD. As oil as a kind of efficient and clean energy is getting more and more people's attention, human beings have a long history of using wind energy. Many countries have long used windmills/wind mills to use wind energy. The wind power line I designed is a form of future urban transportation built with wind energy. The special line is a transparent tunnel. There is a vent at a distance, forming a stream of air. The people in the future can drive on the wind-powered vehicle. The tunnel is really refreshing. Without fuel, there will be no exhaust, and our city will stay away from pollution and become more beautiful.

Depleted five years ago, now on the road are electric cars and hydrogen-powered cars. Hydrogen is a new clean energy source that is both efficient and environmentally friendly. It is abundant in water molecules. People can separate them by electrolysis for people to use in large quantities. Humans have developed engines that use hydrogen as a fuel. After hydrogen is burned, it can be reduced to water vapor without polluting the environment. So people no longer use environmentally friendly petroleum fuels.

Humans should use resources sparingly and carefully protect our planet. We only have such a planet. If one day, the earth is destroyed, the earth's resources are exhausted, and we can hardly get it from other places. We must cherish the 'resources' - the gift that nature gives us.
