Mechanical engineering Project Ideas

In the field of mechanical engineering, we have a vast range of topics to select from. At present, companies and governments are dealing with two issues. First, is about global warming and the other is about competition.

For both these issues, mechanical engineers can contribute a lot. For example, to improve the competitiveness of the organization, you can build automation tools or robots which can help the company to improve its efficiency and similarly for global warming, you can bring some news ideas to either save energy or generate it without doing harm to nature.

The biggest positive about these is that solutions to both these issues are going to come from mechanical. This is the reason, I always recommend students to select topics which are related to either robotics or renewable energy.

I myself tried to find all the latest topics from around the world and write about them to give you some more insight into what's happening around.


Robotics Projects Robotics would be a good choice in mechanical projects: Robots are very attractive in comparison to other projects and if everything goes well they will make you win.
Mechanical Projects related to Robotics

Though I  have written a separate post about robotics here as a starting point I would like to share all important links in this section. Using given links you can enhance your knowledge before building your own machines.

Solar Energy Projects 

Topics based on solar energy is one of my favorite in mechanical engineering because despite its easy to understand working and concept, work based on this energy is very useful and effective for our future energy needs.

Concept: Generally they work on this concept:

Solar Energy --> Solar Panel --> Electricity --> Machine(Grinder, Juicer, Mobile Charger, Bag, etc.) or Storage(Battery)
Solar Energy--> Heat--> Cooking, Boiling, Water Filter, etc.

The important thing to consider in your assignment is that how you can improve its efficiency either for boiling purposes or for heating. For eg.  Recently discussed Spherical cell concentrate more sunlight at one place and therefore generates more power similarly scientist have found out that nano solar cells are more flexible and more efficient than any other cell available.

Solar Compressor:
You can build something which gets its power from Sun Energy. For e.g., power your AC of a small room using a compressor that gets its power from panels.Such as Solar Powered Air Conditioner
In this example, it is a small room. Half-ton capacity will be sufficient. You will need at least kWh/24 hours. This may require 10 to 12 square meter panel plus battery and inverter.
Books on Solar Energy (pdf): 

Hovercraft Project

It would be awesome if you design a hovercar using tools of your house.

Video and Complete Explanation of Stirling Engine

Stirling Engine Mini RC Car: We had discussed both Stirling Engine and Remote control cars in two separate posts. In this post, we will combine these two technologies.

Sun Powered Stirling Engine Generator:

Windmill Projects:
Concept Diagram of Windmill

We all know how we can generate electricity using windmills with the help of its revolution energy and turbines. I have tried to list out some other important stuff we can do using this energy. Though I have written independent articles only on windmill projects but the sky is the limit for what you can do with this energy. In my opinion, if anything which can produce rotational energy instantly is wind energy and mini projects can be built and tested using a small room fan. With all these benefits, I will recommend you to give it a chance. In any mechanical projects science fair competition, you can give a demonstration using the fan.

Projects based on trains
Steam engines 
These engines are powered by steam and building them will help you to understand the concept and working of steam engines. Almost all mechanical engineers study about them in their introductory class of engines itself. Though steam engines are the most ancient engines, it is still one of the most widely used engines. Thermal power plants are one of such use. Nowadays, due to the problem of global warming, we should find a way to produce steam using renewable sources of energy.A couple of renewable steam engines, I discussed on this blog are Solar Powered steam engine and Solar Turbine Generator.

The most exciting thing about this engine is that we can still view its most raw form as a steam engine powered trains.

Light Weight Floating Wind Turbine: Whenever we think about the wind turbines, the first picture comes to our mind is of big farmland with a large turbine. Light Weight turbine is completely opposite of that and not only that, it floats on water too.
Biogas Powered Water Heater 
Bicycle Powered Cell Phone Charger: Have you thought about charging your cell phone using your cycle. This idea would discuss all that.
The steam engine powered Bicycle: Whenever we thought about steam engines, the first thought comes to our mind is a train engine, but have you ever thought of steam engine powered by cycle?
Mechanical Sprayer: Spray pesticides using human energy instead of fossil fuel or electricity.
Mechanical Creeper for Disable Person: This idea is one of my favorites because we never think of difficulties faced by differently-abled people while working below the cars. This project will help understand his or her situation effectively.

Hello everybody,

I am a fifth year architectural student and I am looking for engineers to help me design production machinery required for a hemp farm. Basically I need an machine that does everything separates the seeds from the stalk, the fibre from the hurds. I would like the seeds then to be crushed and the oil produced to be bottled.

SO do you fancy a challenge, do you want to get involved if so then please email me at

thank you

Emer O'Neill

Hello sir...., could u plz help m by giving ideas related to latest mechanical projects plz sir....! Leave the suggestions to m email i.d:

Manu Prakash said...

Thanks a lot sir.....

Thank you for your ideas.....

Actually I was thinking about one of the ideas you told.... Seawater desalination plant using hydraulic pressurizer at one end and solar/wind power suction unit at the other end..... using reverse osmosis technique...... How about the feasibility of the idea?
Is it possible to create such a huge amount of reverse osmotic pressure from such sources, since I read that reverse osmosis and the desalination plant requires huge pressure....

Any way thanks again for the ideas and thanks for replying fast

@viswakanth.....Salt water can be used as alternate fuel because as Kanzius (inventor) claimed under the right conditions, salt water can burn at high temperatures.Read more about his story at
