I am no rocket scientist, but here some of my ideas:

General Sciences

- An alternative to cooking gas. This idea describes about how hydrogen generated using solar energy can be used as a substitute to cooking gas i.e. LPG.

Medicine/Biology/Life Sciences 

- The mechanism of time perception. This idea explores how tagged THC (Δ⁹-tetrahydrocannabinol) can be used as a tracer to identify the mechanism of time perception in the human brain.

- Prolongation of human life span by “preserving” the thymus gland The body’s immune system depends on the thymus gland. The thymus gland diminishes with age and so does the body’s immune power. If we were to preserve the thymus gland in some way, will it result in a more powerful immune system and thus prolongation of life span?
