Despite being one of the cheapest and most reliable sources of renewable energy, there is no harnessing of heat from the ground outside of Iceland. In this video, we are going to learn what is Geothermal energy, its advantages, and disadvantages, what are those challenges that stop us from getting energy from Earth, and much more. So be sure to watch until the end.

What is geothermal energy?
Geothermal energy is heat in the earth. The word geothermal comes from the Greek words ‘geo’ which means earth and ‘therm’ means heat. Geothermal energy is a renewable energy source because heat is continuously produced in the earth. People use geothermal energy to bathe, heat buildings, and generate electricity.

How does it work?
Humans can harvest geothermal energy by:

-Geothermal power plants, using heat from within the earth to generate steam to generate electricity.
And,
-Geothermal heat pumps, using heat near the earth’s surface to heat water or heat buildings.
Geothermal power plant
In geothermal power plants, wells are drilled 1 or 2 miles into the earth to pump steam or hot water to the surface. You’ll likely find one of these power stations in an area with lots of hot springs, geysers, or volcanic activity, as these are places where the earth is extremely hot just beneath its surface.

Now, let’s break down its working step-by-step:
-Hot water is pumped from below through a high-pressure well.
-When the water reaches the surface, the pressure drops, causing the water to turn into steam.
-The steam spins a turbine, which is connected to a generator that produces electricity.
-The steam is cooled in the cooling tower and condensed back into the water.
-The cooled water is pumped back to earth to start the process again.

Not all geothermal energy comes from power plants. Geothermal heat pumps can do everything from heating and cooling homes to heating swimming pools. These systems transfer heat by pumping water or a refrigerant-a special type of liquid, through pipes just below the earth’s surface, where the temperature is constantly between 50 and 60 degrees Fahrenheit.

The sun. One of the most powerful energy sources ever available to humans.
The process of exploration this energy began more than two thousand years ago, requiring at first colossal knowledge and skills from a person. Thanks to this labor, today, solar energy has become the cheapest in history. But why, with all its cheapness, is it not used so widely?

Perovskite solar cells are a remarkably cheap solar cell technology and have achieved remarkable growth since their inception a decade ago, sharply increasing in efficiency from 3.8% to 25.2%, near to their theoretical efficiency. Thus, the perovskite solar cell could be the future of solar energy. Perovskite solar cells are a new technology and still needs to be scaled up for commercial applications, but perovskites have the potential to revolutionise the energy harvesting market, with cheap, high efficiency solar energy in the near future. In this video, we’ll explore perovskite solar panels and how they might energize our future.

Part 3: Real World Field Tests now up on the channel: https://www.youtube.com/watch?v=5jl8vHHn7_s
This open source turbine can be built for about half the cost of a 120 watt solar panel, and will produce about ten times the power per day. It can be plugged into any appropriate waterway without the need for earthworks, and uses only basic off the shelf and recycled materials, and basic hand tools.
The turbine is now working and producing power.

This technology was produced in partnership with COACT, an open source green tech incubator in Barcelona. COACT exists to help all kinds of innovators working on green technologies. To learn more, and apply for a residency visit https://www.coactlab.org

And thanks to the good people at Ca La Fou (https://calafou.org/) for the rest.

Once the design is optimized I’ll produce a full open source construction tutorial on
the website: https://opensourcelowtech.org
the Facebook page: https://www.facebook.com/opensourcelowtech.org/
and the Facebook group (which is the main discussion forum): https://www.facebook.com/groups/opensourcelowtech/

My name is Daniel Connell. I prototype and develop basic technologies which anyone can make using recycled materials and simple tools.
The aim is for everyone everywhere to be able to build and maintain their own infrastructure; producing their own energy, food, clean water, communications, and anything else they need.
All designs are open source and license free for any purpose, and full construction tutorials and how-tos are available on the opensourcelowtech.org website.

A couple people have asked if I sell the file for the 3D printed impeller. I don’t, it’s free:
STL (mesh, 28 MB): https://drive.google.com/open?id=18NuQbyD55YhnAM9aj_lBrWgHAxp3iZxE
Iges (nurbs, 14 MB): https://drive.google.com/open?id=1HL_y-HwpomukQ7ORQf2E57Zy7ytoWTKN
Feel free to play around and experiment with them however you like, but please let me know how it goes and what your results are, as that’s always good to see.
It seemed to work ok, but I’m going to instead be using computer cooling fans as they seem to do higher revs at lower toque, and be a lot more accessible in other parts of the world.

03:44 – Hydropower turbines
06:55 – Hydropower Plants

=============================

Electricity is produced by a diversity of energy sources, and different types of technologies.

According to the U.S Energy Information Administration, in 2020:
– Natural gas represented the largest source of energy production, at about 40%
– Coal represented about 19%
– Petroleum at 1%
– Nuclear energy, producing electricity from nuclear fission, represented 20%

As for renewable energies, those have been rapidly varying their share of U.S. electricity.
The total amount of electricity produced by renewable energy in the U.S is about 20%.

Here is a breakdown in 2020:
– Hydropower plants produce about 7.3%
– Wind Generation: 8.4%
– Biomass: 1.4%
– Solar: 2.3%
– Geothermal: 0.5%

Renewable energy has become a very hot topic in today’s world. We see and hear more every day about solar and wind power generation.

What we don’t talk about, however, is that with the increased use of wind and solar energy, comes the increased concern about grid stability.

The equilibrium between how much load is generated, and how much load is required by the grid is a continuous balancing act, which needs stability and is crucial in order to avoid blackouts. The energy generated needs to constantly be equal to the energy consumed.

When it comes to generating power via the use of wind or solar energy, there are uncertainties that need to be accounted for: Either the sun is bright and shining, or it is not. Either you have wind making your turbines spin, or you don’t.

What we are doing by the addition of those energy sources is essentially adding more and more instability to the grid.

This is where hydropower comes in… not only do the hydropower plants have the ability to store fuel (or water!), they also have the ability to respond to grid variations, also referred to as load requests within fragments of a second due to its governing systems that control the turbine’s speed.

That is why hydropower is often referred to as the Guardian of the Grid!

How is hydropower actually generated?
Well… the energy is generated by the same principles ancient Greek farmers used to grind grain: the flowing water spinning a wheel or a turbine.

Hydroelectric power plants are always located near a water source due to the fact that water is the source of hydroelectric power.

Inside the power plants, there are different types of turbines, but for today, we will look into the turbine known as the Francis turbine or the friendly Francis. It takes the friendly nickname due to being less complex to control, with fewer parts and fewer variables.

The difference in elevation, created by the dam, between water level from intake and discharge is what is referred to as head.

With the exception of the not-so-common diversion turbine, which relies on the natural flow of water to create motion, hydro turbines are often built at a lower elevation.

Francis turbines require a low and medium head. This means that the dam is smaller than when compared to the dams needed for the other turbine’s head’s requirements.

Wicket gates are how governors can control the speed of the turbine!
The turbine then turns the attached shaft which spins your generator, to produce electricity. That electricity then travels through power lines all the way to your home… and gives you light!

We have two other types of turbines, the Kaplan and the Pelton turbine.
– A Kaplan turbine has not only gates but also blades!
– A Pelton Turbine spins on air just like the Greek farmer’s wheels.
