Kim Said:What is the initial and final energy used for the following?
We Answered:flashliight: electro-chemical (battery) --> light, heat
car: thermo-chemical (gas) --> electronic, light, heat, kinetic motion
candle: thermo-chemical (fat/wax) --> light, heat
campfires: thermochemical (bio-molecules) --> light, heat
Wallace Said:Could a flame from a candle be used to charge a solar power thing?
We Answered:depends on how efficient the solar cell is. the power from a candle is very small. about 1 BTU, british thermal unit, that is how energy is measured. ie the furnace to heat your house could be about 100,000 BTU's so anyway a candle may put off enough light to power a calculator but they are made to work in very low light. so it depends on what you are wanting to charge. most likely it wont be enough energy.

Lorraine Said:How much lighting do I need?

Less moon more light.
Set an area up that has more lighting and perhaps a reflective material in a spot.
Don't eliminate the throught of some citronella to keep pests away.
Minnie Said:When God said Let There Be Light Is that the day He learned atheists needed more than electricity to believe?
We Answered:The atheist cannot deny that when a realization comes, it flashes as light upon his mind and the realization is a completeness, not broken up into thought, like limited mind.
