50 Creative and Unusual Ideas From Amateur Engineers

Although the original idea to heat a pool using a water pump combined with fire to heat the water, these guys found another solution that is incredible and dangerous at the same time. This system eliminates the piping and water pump and replaces them with a much simpler tool, the wheelbarrow.

All they did was put charcoal onto the wheelbarrow and light it up. The heat will expand to all regions of the wheelbarrow. However, one small nudge could cause a catastrophe like the charcoal could melt a plastic pool, experience third-degree burns, or the pool gets dirty.
