Ok, cool idea time.
Lets start with the crafting recipes, the solar staff, for lack of better term, will be crafted using a solar panel, a water cell, and a wind mill.
Now, the next piece, the crystal energizer, is a lapotron crystal with glass all around it.
The last piece is a solar concentrator. (Okay, I lied, no recipe, its really just a solar panel that you place)
Now for the actual idea, its basically a solar flower, but not in the traditional sense, using tin cable and solars. Its actually a multi - block structure. You place down 2 Crystal Energizers with a Solar Staff on top. Then around the bottom Crystal Energizer, put 4 solars concentrators on each side, so that you have a 9x9 of solar panels with the Solar Staff and Crystal Energizer's in the center.
2nd to last, the logic behind my idea. This type of setup is used to destroy toxic waste in real life. The sun is reflected off of the solar panels/mirrors, into the central collector, which concentrates the heat, to over 5000C, which as you can imagine destroys just about anything. The scary thing is that very little surface area of the combined solar panels is needed. In real life, some power plants use the heat to make steam and spin turbines.
Last, and not least, the total cost and output of such a device.
Coal: 243
Cobble: 656
Copper Dust: 540
Diamond: 2
Iron Dust: 826
Lapis: 12
Redstone: 512
Sand: 259
Sticky Resin: 1080
Tin Dust: 328
Water Source: 1
Output: 512 eu/t , and the cable can only be connected via the bottom Crystal Energizer. It only works during the day.
