Mechanical Engineer, Engineering Design & Technologists
This mechanical engineering internship centres on the solar-powered river-cleaning machine Earth5R built for the Mithi River in Mumbai, and a mentor guides your work at each step. You study how it works from its build records, map each part of its design and propose improvements for Indian rivers.
For school and university students curious about how machines are designed, who want to study one built for a real Indian river. Online, with field work near where you live. The fellowship is paid because every fellow receives time and attention from senior researchers and leaders.
Mechanical engineering and sustainabilityMany environmental fixes depend on machines. Composters, recycling equipment and river-cleaning machines all have moving parts that carry loads and wear out. Mechanical engineers design these parts and choose materials that last. They also keep energy use low, which matters when a machine runs on solar power. In the field, rain and salt water test every joint, so a good design keeps working in those conditions.
Earth5R built a solar-powered river-cleaning machine for the Mithi River in Mumbai with the UN Technology Innovation Labs, now UN Global Pulse. It was first built in Finland and then rebuilt for tidal and monsoon conditions. As a fellow you study it through photos, videos, build documents and view-only CAD designs, and work out what had to change between the two builds.
This work links to the UN Sustainable Development Goals:
Goal 6, Clean water and sanitation and Goal 9, Industry, innovation and infrastructure .
You join Earth5R’s live work through your own subject. Your mentor shapes the final project with you.
- Improve one part of the design – Pick one part of the machine, such as how it collects or holds waste, and propose an improvement for Indian rivers with sketches, simple calculations and a material choice.
- Drum composter redesign – Study the drum composters Earth5R designed from reused industrial containers for housing societies, and work out how to make them easier to use and longer lasting.
- Assembling a trash boom on the riverbank – Inspecting a composting machine.
Every fellow moves through four phases. Each phase is checked by your mentor before you move on.
Along the way you take part in research conversations with professors at MIT, Oxford, Cambridge, LSE and other universities, and ask your own questions. See how FIELDWORK works.

Strong mechanical engineering programmes look for applicants who can explain how a machine works and justify a design choice with simple numbers. A fellowship project gives you a documented design study of a real machine, reviewed by your mentor and recorded on earth5r.org. Students use a mechanical engineering internship to build a record of real work for…
