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.

Check out what the moon phase will be that day.

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.

Discuss It!
