Question

What are some practical, small-scale engineering problems, and what are the alternative solutions to solving these specific problems?

Answer 1

Two examples are quoted below:

1. Energy generation for small scale household or industrial use: How to address the energy needs of a small scale building using cheap energy sources ? One solution is to use the electricity provided by the state companies. But an alternate and non conventional approach would be to switch to solar energy. Let solar panels over the roof of the construction space serve the energy requirements.

2. Automobile sector: How can novel mobile units for automotive industry be invented ? An answer to this could be that the automotive industries should make more gas and diesel based small scale locomotives. But an alternate solution would be to implement hydrogen base fuel cell driven locomotives which would not only be cheap but also environment friendly.
