Lighter fluid or lighter fuel may refer to: Butane, a highly flammable, colourless, easily liquefied gas used in gas-type lighters and butane torches; Naphtha, a volatile flammable liquid hydrocarbon mixture used in wick-type lighters and burners; Charcoal lighter fluid, an aliphatic petroleum solvent used in lighting charcoal in a barbecue grill
Solar powered flashlights can be used in remote locations where it is impossible to find any source of electricity except for solar power. [4] A built-in solar cell array in a hand-held product has a very small capacity. The light output and run time of the solar flashlight are limited by the amount of energy that can be absorbed in a day.
The use of lighter fluid is somewhat controversial as the substance is combustible, harmful or fatal if swallowed, and may impart an unpleasant flavor to food cooked upon fires lit with it. The sale of petroleum-based charcoal lighter fluid is regulated in some jurisdictions due to its potential to cause photochemical smog through evaporation ...
A solar lighter is a pocket-sized stainless steel parabolic mirror, shaped to concentrate sunlight on a small prong holding combustible material at the focal point. A revival of an old gadget marketed as a cigarette lighter by RadioShack in the 1980s, it is a useful hiking and camping accessory as its functioning is not affected by having been ...
The sun and planet gear converted the vertical motion of a beam, driven by a steam engine, into circular motion using a 'planet', a cogwheel fixed at the end of the connecting rod (connected to the beam) of the engine. With the motion of the beam, this revolved around, and turned, the 'sun', a second rotating cog fixed to the drive shaft, thus ...
In solar cells which increase in efficiency due to light soaking a typical deformation (often referred to as an S or kink shape) is seen in the I-V curve before illumination. After illumination during some period, the short-circuit current density and open-circuit voltage go up resulting in a higher fill factor.
