Depending on where you are, Planet Earth's surface generally receives from 1 to 4.5kWh per m2 of Solar energy per day.
This amount of energy is sufficient to give you sunburn with sufficient exposure time, but not enough to cook.
Since critical temperature is required for cooking, if we can concentrate the amount of solar energy to a small point, the concentrated solar thermal energy could be raised to a temperature that is sufficient to do meaningful cooking. Imagine using a magnifying glass to concentrate sunlight to a point strong enough to burn a hole on a sheet of paper.
Another way of converting sunlight into cooking fuel is through trapping and accumulation like that of a glass house. Trapped solar thermal heat if accumulated and prevent from being lost to the ambient can raise to a critical temperature that is sufficient for cooking.
The key to mining free energy from the Sun as fuel is therefore in concentrating sunlight to reach a critical cooking temperature point of at least 65degrees Celsius through the process of concentration and/or accumulation.
Parabolic and Fresnel type cookers concentrate sunlight to a smaller point to reach temperatures that cook and Box Cookers and Solar Kettles using solar vacuum tubes technology accumulate trapped solar heat and prevent its lost to the ambient by insulation. Panel Cookers are hybrid Solar Cookers employing a combination of concentration and accumulation.

Thinking Outside the Box
A buzz phrase, a jargon, widely mentioned but unfortunately least understood fully.
Thinking outside the box presupposes the ability to think in the first place.
If one is not even capable of thinking, than really thinking within the box is not very possible, let alone outside.
Why is thinking so difficult, one may think.
Thinking is a learned ability as much as it an innate one.
Thinking and language is also intricately linked since we all must reason in our mind or even aloud verbalised or written in script through a reasoning media: a language.
However, empirically, whilst language and thinking are intricately linked, it does not necessarily mean that people with language disabilities is in any way concomitantly disabled in thinking abilities.
Deaf, mute, blind and illiterate people who had no acquired language abilities are known to be able to think reasonably and creatively.
The Swiss behaviorist Piaget hypothesised that thinking is an innate ability because babies even before acquiring the ability to verbalise speech are able to reason and solve problems. It is as if we were all born with an innate language free reasoning ability before we take up a learned language to function as the reasoning language media.
It is also apparent that since language influences reasoning, and since all languages are culture bias, the language a person uses to reason do limit or box a person's reasoning ability.
For a ideas to flow, there must not be any limits but total freedom.
Anyone who aspires to greatness must be given the total freedom to fly like an Eagle and not be boxed and bound on the ground like a Turkey.
Sometimes we box ourselves by our fear and sometimes by our ignorance.
We could be living in a totally free country and yet our thinking could be boxed in by our culture and religion, we fear to think beyond what we think our religion allows.
To me, a religion or culture that imposes on how we ought to think is despotic.
God is not a despot because he made us no robots. On the contrary, he made us humans with a free will to choose and integral to free choice is free will and to free will the freedom to think.
When we are fearful even to think the seemingly forbidden things, we deny the greatness of the Almighty in making us humans with a free will.
Similarly, let no man or angels, fallen or otherwise dissuade us from the basic right God has given us and most enlightened governments that followed in tandem to support: the Freedom to Think.
Thinking Outside the Box presupposes the ability to think and to think freely without any inhibitions or limits as a 'Box' symbolises: constraints.
It is easy for leaders, political or otherwise to urge the people to think outside the box, the irony is who created the box when none is supposed to be there in the first place and do they impose on others what they themselves are incapable of doing.
Let it not be like a father crab commanding its children to walk straight, let him the leader learn or even undergo therapy to walk straight first!
Asking his people to think outside the box when they are still imprisoned in the box is one big joke leaders can command their people to be.
Do I hear a familiar voice from the distant past in the land of the despotic Pharaoh?
Just as Moses told Pharaoh, the message from the Great I AM reverberated through the ages:
Let My People Go and Let My People Grow!

The Way of the Cycle
The Way of the Cosmos is the Way of the Cycle, with built-in Renew-ability and Sustainability, where there is no place for waste, as one organism's waste is another organism's food, where death sustains life and where nothing is new; only fresh.
Carbon Cycle, Nitrogen Cycle, Hydrological Cycle and yet we humans are notorious for breaking and disrupting Cycles and reaping the dire effects from a broken cycle of renew-ability and sustainability.
We used to waste not and therefore want not.
We put back to the ground, what we took from it.
We eat the produce of the land and gave back our excreted waste to the land as food for the flora and fauna as they fed on the nitrogen and carbon that produce the food we need, thus completing the Cycle.
But see what we do now.
We deposit our waste in a septic tank and buy expensive mined minerals to fertilize our land to produce food.
Not only did we break the Cycle of Sustainability and Renew-ability; we destroy as we create: mining lands to extract minerals, destroying more when we ought just to return our waste to the land.
Look at the glass of water you will be drinking today.
Where did it come from? From the tap linked to some reservoir which takes its source from a river or some other body of water.
There is no new water, every drop is recycled, reused from the Jurassic Age.
Your drink is used and passed out as urine and in due course, it will return as drinking water again as it goes through the Hydrological Cycle Process where the Sun heating the sea and the land caused water evaporation and return the precipitation.
Yet again, we break the Cycle, by polluting the water through our greed and dimming the Earth through our excessive burning of fossil fuel to fuel our economic pursuit.
We have only one Earth and yet we are killing ourselves by breaking all the Cycles that sustain us.
When will we realise the value of flowing with the Cycle of the Cosmos by keeping the Way of the Cycle.
What fools we are, knowing the cost of breaking the Cycles, yet ignoring the value of preserving them.
