Amazing! Lit up the world with your body

Generally, flashlights are powered by batteries like AA,AAA,18650,16340 or lithium since its invention. More batteries are placed in series or parallel in high power flashlight. our 1000 lumen flashlight is loaded with  1PCS of 18650 battery or 2 CR123 Batteries. While 3000 lumen led flashlight Bronte X30 uses 3PCS of 18650 batteries.The flexible flashlight Bronte V2 is compatible with either 1 or 2 AA batteries.

However,in order to save energy and protect the environment, new echo friendly energies  are encouraged to be developed and put into daily use.Thus, solar flashlights or lanterns  are launched in the market .

This is a good try though its efficiency is not high.Currently,researchers have Focused on human heat and successfully powered a high power flashlight with human body heat.This was created and tested by a teenage girl Ann Makosinski.

4 peltier tiles are used to convert the temperature differences between body and room into electricity to lit up a high power flashlight.One side of the tiles is heated by our body and the other side is cool outside.This causes  a temperature difference.When this differences reach up to 5 degrees,electricity will be produced.In the demo, Ann had lit up a high power flashlight  for 20 minutes at very low lumen. This is not a good performance.However, it is a striking step and has a long way for improvements and putting into commercial practice.

This is a good try and it is believed that one day  all electronic appliances including 3000 lumen led flashlight will need no batteries or electricity produced by coals or other resources,which can bring pollution to our environment. Our body will become the largest power plant.
