The results we a 50% reduction on focal point diameter but also a significant power drop.

DIY – Attempt at home made solar panels – Wasn’t a good idea!!
This is my attempt at building my own solar panels. I completed the panel, but using Lexan and Clear Epoxy resin didn’t turn out quite like I expected. Granted this was my 2nd attempt. For the most part I would recommend simply buying a decent panel. for the time and money I spent I could’ve bought a 200Watt panel from a discount retailer. Also, I would definitely not put a homemade panel on the roof.
THE DIY SOLAR PANELS ARE SURVIVING!!!
I took some video of the home made solar panels to show you how well they are surviving with the weather. 9 of the 9 are running just fine with no problems.
Solar “Death Ray”: Power of 5000 suns!
The R5800 is my latest and greatest solar creation. Made from an ordinary fiberglass satellite dish, it is covered in about 5800 3/8″ (~1cm) mirror tiles. When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 times normal daylight. This intensity of light is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5’9″ and is 42″ across. Donations to help fund future projects are greatly appreciated: www.paypal.com music: “hypnothis” www.incompetech.com Coming spring of 2011: Sun Runner 3 R23000 (R23K) Area of dish aperture (elliptical)= (pi x 102cm x 73cm)/4 = 5848 sq cm Area of focal point (circular)= pi(0.6cm)^2 = 1.14 sq cm Concentration Power= 5848/1.14 = 5129 then rounded down
Wine Bottle Cutting 30 seconds Perfect Edge Resealable GreenPowerScience Bottleneck Guitar Slide
This is the ONLY glass cutting method that cuts bottles perfect every time. A flaming string is not good. A blow torch is a BAD IDEA. Glass hammer will not work well. www.greenpowerscience.com I talked to a few people who have cut 1000′s of bottles, they say “you cannot get a perfect cut, top will always be ruined” Not true. Perfect bottle cutting 95% of the time. Glass Bottle Recycling. Reduce Reuse Recycle. Make glasses from bottles. Glass Bottleneck Guitar Slides. DIY Bottleneck, Slide & Lap-Style guitarist.
