She can consider using agricultural waste or dried dung.
Explanation:
No doubt, biomass has become a crucial source of energy to the society, with almost 90% of the households in rural area now relying on biomass for energy. Biomass has become a great option for household heating and cooking. It is locally available and abundant. It is a clean type of fuel, unlike fossil fuels and it somehow helps in cleaning our environment as it traps carbondioxide. Some common types of biomass include dried dung, agricultural waste, or even charcoal.
Molly can harness the Biomass-based fuels. This type of fuel provide a great alternative since they can be generated from crops, tires, computers, and pretty much anything else other than nuclear waste.
One particular avenue being explored is the use of food waste, which is readily available and can be converted into biofuel through various processes.
The transfer of energy means, in convention process, transport of matter. In this case, hot water has lower density than cool water. The water with less density ascends and leaves gaps that are occupied with cooler water "packages".
