Solar Energy Concentrator

Purchase: http://hilaroad.com/video/ This video demonstrates how solar energy can be focused with a curved mirror.
Once focused this energy can be used to cook food, sterilize water even create electricity.
Includes an explanation of Energy, Power, Joules, Watts. Examples of radiant, heat, chemical and kinetic energy are given.
Includes links to directions for constructing a simple solar concentrator.

Simple and brilliant!

we dont need oil, all alternative energy sources are already in place,

[cepedaruben1]

We like to have energy supplied at will. We would need the sun twenty four seven for this contraption to be practical and we all know that this isn't going to happen. So this is not a good idea for most of us. Also how will it follow the constant movement of the sun by itself? This is something already thought up many moons ago or in this case many suns ago. Come up with a brighter idea utilising what you already have add a solar battery pack and a powered servo motor to at least follow the sun.

Очень хорошо. Понятно. Дочке очень понравилось.

@FarquharDingleberry

He said it in a condescending way (from my perspective), so he got a condescending answer. Simple as that.

[haiderbird2000]

very nice

[remboy3000]

Renewable resources should be used for the energy that we use primarily today. Fossil fuels should be like back up energy or something. But why isn't it happening? It seems like a good idea, or am I missing something?

@moecat1000 Pointing out flaws is helping, it allows sensible people to pause, reconsider the arguments, perhaps change their minds or consider points of improvement on their existing plans. Your disregard for sylverdrag's comments by branding her\him a naysayer is very narrowminded.

@osimnod

Can't run on water, we would suck our planet dry.

[moecat1000]

@sylverdrag there is always one nay sayer..if your not helping shutup

[sylverdrag]

Hum, so a solar plant the size of a small city in the desert (an area which receives a very large amount of sun energy) is barely enough to power a small city today? This is so typical of "solutions" made without understanding the real magnitude of the problem. We need a solution that can produce 100 times our current energy consumption. Not a "solution" that can barely keep up with our current needs and requires more land than we use for producing our food and lodging.
