A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. [1]
Many cavers prefer this type of unfocused light as it improves peripheral vision in the complete dark. The reaction of carbide with water is exothermic and produces a fair amount of heat independent of the flame. In cold caves, carbide lamp users can use this heat to help stave off hypothermia. [8] Acetylene is produced by the reaction: [9]
The National Historic Lighthouse Preservation Act of 2000 allows lighthouses to be transferred at no cost to federal agencies, state and local governments, nonprofits, educational agencies, and community development organizations so long as they comply with the conditions standards and can financially care for the lighthouse.

The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its British inventor, Francis Thomas Bacon, is one of the most developed fuel cell technologies. Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70%.

The hot gases produced are lost up the chimney, thereby reducing efficiency just as in an open coal fire.
