Yes it is safe when the power input is controlled
Solar energy is certainly safer than nuclear energy, but decidedly more expensive with much greater space requirements...at this time. As solar and other alternative energy sources are developed, it is reasonable to assume that the costs will decrease. Whether or not they will ever decrease to the costs per kilowatt hour that nuclear energy can achieve remains to be seen.
no one knows that yet.
Solar ovens are able to cook anything from an egg to a whole turkey. This is due to the energy generated by concentrated light.
calculators,cars ,cook food
In a solar cooker, solar energy (light and heat) is absorbed by the reflective surface and converted to heat energy. This heat energy is then transferred to the food in the cooker, causing it to cook or heat up.
Uh..., you heard of an egg cooking on a sidewalk?
There are many a few are solar energy, sum people use it to cook
We are most familiar with two forms of solar energy: solar thermal energy, which uses sunlight to heat water or air for heating purposes, and solar photovoltaic energy, which converts sunlight into electricity using solar panels.
Solar energy is safe because it is radiant energy from the sun. No chemicals or pollution are produced from the use of the sun. It's a lot safer to produce than the fossil fuels which are used to create the light and energy we waste in our everyday lives.
Radiant energy -> electrical energy -> thermal energy
People use solar energy, because if solar energy can be used for electricity and heat, we have to use electricity,or to use heat. This is either to see or to cook and to stay warm with electricity and heat.
A panel cooker is a way of using solar power to cook an item. The advantage of using a panel cooker is that it is using solar energy and not electricity.
