These renewable energy videos range from the inspiring, and the revolutionary, to the educational, genius, and futuristic. To see what can be done when you harness power from mother earth is truly impressive.
When he was just 14 years old, Malawian inventor William Kamkwamba built his family an electricity-generating windmill from spare parts, working from rough plans he found in a library book. For me, this is one of the most inspiring videos on home renewable energy that I’ve ever seen, and one that I hope you’re familiar with. Essential viewing.
Lets start with something relevant. This was made just a few weeks ago, and it documents one of the most renewable countries in the world: Germany. Roughly half of the world’s solar panels are in Germany, and there are plans to create off-shore wind farms to help contribute to Germany’s renewable energy, whereas US politician Mitt Romney has recently confirmed that he would end US wind power subsidies if he were to get into power.
Germany really are leading the way. They’re getting rid of nuclear, phasing out coal, and trying to reach 80% renewable energy by 2050.
UK firm Riversimple are designing a truly alternative car. It runs on hydrogen power, has a carbon fibre body, and is completely open source. Anyone will be able to download the vehicle design and the software the car needs to operate.
What if you could light your room in the day time, using recylyed materials, and just a little bit of bleach and water? That’s exactly what Alfredo Moser did. He worked out that you could put the bottles in your roof, and the sun would burst through, lighting the room. Sure, it’s not going to work in the night time, but it’s free lighting during the day, giving off the same amount of light as a 50W bulb.
The Solar Impulse team members were cheering Thursday as their experimental plane completed a 24-hour flight. It proved the solar-powered plane was able to absorb enough energy throughout the day to fly through the darkness of the night.
This animation shall explain the biogas technique. You will be shown the process of a biogas plant from the delivery of feedstock to the output of the digestate.
This car that runs on compressed air, is a French invention that orchestrates old technologies into a new chassis. The technology is very cool, even if the video does go off on a bit of a tangent about perpetual motion (which isn’t to be taken too seriously).
Renewable energy? Not exactly, but it’s all about harnessing the world’s natural energy sources and materials.
In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance.
In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.
Solar-sintering aims to raise questions about the future of manufacturing and trigger dreams of the full utilisation of the production potential of the world’s most efficient energy resource – the sun. Whilst not providing definitive answers, this experiment aims to provide a point of departure for fresh thinking.
Enjoy this lecture from Margot Gerritsen, Associate Professor of Energy Resources Engineering at Stanford, as she discusses the recent upswing in the development of large-scale solar projects, with elaboration on fast-track projects, the political, economic and financial barriers to implementation, and utility integration along with several current case project examples.
It’s over an hour long, but it’s worth it.
Short, but kind of fascinating to see the future technology.
A giant rubber snake could be the future of renewable energy. The rippling “Anaconda” produces electricity as it is squeezed by passing waves. Its developers say it would produce more energy than existing wave-energy devices and be cheaper to maintain.
The passage of each wave squeezes the rubber and produces a bulging pressure wave that travels down its length. When the bulge reaches the end it sets turbines spinning to generate electricity.
