Problem statement:
Homeless poeople lack a way to keep themselves warm, especially during frigid winters.



Variables to consider:
-Thermal conductivity of different materials
-Affordability of materials
-Portability of product
-Price/Value of product



List of theories generated:
-Best way to keep warm: by trapping air, since air is a freely available resource and is also a good insulator of thermal energy



List of ideas generated:
-Use a device that has a dynamo to charge batteries
-Action of running the dynamo keeps the people warm
-Power from batteries can be used to spark/burn newspapers or cardboard or power a
fluorescent lamp

-Have a double layered overall that covers the entire body
-Layer of air provides insulation
-A tube connects the chest portion of the suit to a box.
-Things (Newspapers, cardboard, etc.) can be burnt in the box and the hot air will travel up the
tube and into the suit.
