Solar Furnaces vs Satellite Dishestoc
by Douglas Bremner

What is a Solar Furnace and how does it work?
A solar furnace is an array of approximatly 63 parabolic mirrors that redirect the suns ray all to a cubicle right on the focus of all the rays. Solar Furnaces can produce about the same energy as 2,500 suns, but they can be intesified to create the same amount of energy as 50,000 suns at its focal point. The largest made Solar Furnace today is the odeillio furnace which there is a picture of bellow. They produce pure energy without any pollutants and once they are set up they can eventually start to save you money

This just shows how much heat this produces    

What is a satellite dish and what does it do?
Satellite Dishes are the tool that allows you to have satellite TV. There are 2 kinds, the receiving and the transmitter, they are the same but their feed horn does a different purpose. The transmitter has the feed horn transmit a signal that reflects off the parabolic dish (the same as a concave mirror) which narrows the signal beam and sends it towards its designated area. The receiver has those beams hit its parabolic dish that sends the beams to its feed horn at its focal point. Through those feed horns it converts the radio radiation into video and sound to project through your TV if you have Satellite TV.



Similarities and differences of a Solar Furnace & Satellite dish
A Solar furnace and a satellite dish are very much alike... they both use the same parabolic concave like dishes/mirrors to focus their desired radiation/energy at a certain point. The only differences is that a Solar furnace creates energy with its radiation and the satellite dish just converts its radiation into a picture you can watch and hear on your television. The biggest difference is that the solar furnaces require tons and tons of cash to build and massive thought process to get every mirror at the right curve. In general their tactics are the exact same in how they use the science of optics to reflect their radiation.
