Hi Doug,
Madder is Rubia tinctoria. It is in the gallium family (or something). It looks a little like woodruff which is also in the same taxonomic group, but madder has way more color property than the rest. You use the root of plants that are 4 years old.

Weld is Reseda luteola. It grows like a weed and you use any part of the top of the plant. The green leaves turn wool bright yellow. Gorse, goldenrod, broom, and turmeric are also good sources for luteolin. (Again, weld has the most.)

Did the guy that made that youtube video ever explain his reason for the dye? And, is there a color preference?

I hope this helps.

Jenna,

Great info actually I enjoy the contribution....

Anyone else making any progress I am currently trying to devise a way to turn a garden style 8ft wind turbine into a generator with the proper mods it should be possible but planning is an important step to the puzzel.

By the way the panel I have that I made has been charging a car battery which is charged every day and used every day the things I use are lower power devices using a 12v 15 amp inverter with fuse inline I LOVE IT!:

Energizer 15min charger
2 MP3 Players a creative zen 20gb and a touch screen model
1 cell phone
and occasional I hook up the 13 watt cfl which is as bright as the typical 60 watt.

Solar is a real thing as well is wind great projects man with solid proof why don't we work to make these things more viable for people to own I have used magnifying glasses and the results were interesting to say the least under an ordinary cfl light it put out 1.92v and a fresnal lense or magnifying sheet friggin put the power to 3.12v...

Maybe a combination of magnification and home made may make homemade a viable solution dunno just a bright idea hanging in the wind

I just need to purchase or obtain an LCD screen. Does anyone know where an LCD screen can be purchased?

@ Resin

You might want to browse eBay for non-working TV/monitor/laptop "for parts" sales.
No need to pay for a working device and dismantle it for parts when you can pick up something on the cheap and save another landfill deposit (speaking of which, keep a wary eye on trash day for the odd dead LCD device that might show up out next to the curb. It's not supposed to be disposed of that way, but it happens quite often and is picked up  by the garbage truck without complaint).

Also, should the efficiency be enough to warrant it and you would want to build more, You could take out an ad in your local paper offering to buy dead LCD devices. How much someone wants to sell you trash is a lot less than what they want to sell you a TV, and there is no shipping.

  That does look easy enough and it even comes out looking like those oakley sun glasses that are coated with that rainbow colored stuff. if i were to take a leap forward in thought. The hot gas/smoke may be all that is needed when trying to stick the material to poly type sheeting like a plastic fresnel lens. The groves in the lens should provide more surface area. The method may work for a number of metals with low melt temperatures.Good find. I always wondered how they do that.

This is a great thread, and very tempting to make these cells!  There's a wealth of info about Graetzel cells at wikipedia -->

http://en.wikipedia.org/wiki/Graetzel_cells

They go over the efficiencies of DSSc's, which are comparable to traditional silicon-based solar cells. DSSc's can typically be 11% efficient and traditional Si about %12 to %15 typically. DSSc's produce more voltage, ~ 0.7V, than traditional Si, ~0.6V, but DSSc's produce less current, 20 mA/cm², as compared to traditional Si, 35 mA/cm². BTW, those figures are not the power figures combined, but are simply the open-circuit voltage and closed circuit (shorted) current. DSSc's produce just about as much overall power as traditional Si.

DSSc's degrades from UV light, but that's not a big problem because they simply place a thin UV absorbing coating.

According to wikipedia, DSSc's are currently the most efficient third-generation solar technology available.

It would help to have an inexpensive method of making the glass coated transparent conductive plates. One method is to place an metal on a ceramic plate just under a piece of glass inside a vacuum, and heat the metal. In this case, the vacuum does not have to be a high vacuum, although a high vacuum would help. A cheap $60 rotary vane pump from Harbor Freight should be sufficient -->

This method is called deposition. There are a lot of methods of coating conductive layers on glass. Some better than others. It can be difficult to apply a pure metal coating, rather than an oxide coating. Metal oxides are very poor electrical conductors. The presence of air, which contains oxygen, will easily oxidize the heated metal, hence the vacuum pump. The vacuum method is one of the best, but there's probably a lot easier methods that work good enough.


Solar combined with wind turbines seems like a good complete package. They say that when the wind dies out the Sun usually comes out, and vice versa so one of them is often producing power.

You will need to consider the metalized plastics may also have a protective coating to prevent the coating from being easily scratched off or oxidized while in storage before use. printed materials like most balloons will will have a protective coating to protect the printing or image. Maybe a bit of sand paper to expose the metal layer before checking it.
   Those balloons seam to last for years stuck in trees so they weather well enough. Companies that manufacture the plastic may provide the answer with little more then a phone call. Clear mylar will begin to yellow and become dull after a few yrs. If you ever run across one of those big projection TV set in a box they have a perfect mirror coated plastic sheet in a frame inside the unit to reflect the image onto the screen from the three projection guns. I really enjoy gutting those big TV's lots of goodies in them.
   When these LCD big screens start to go bad and end up in the trash that will be a fine day. i would not discount the chance to use the conductive coating as a diode if it is possible with some measure of oxidation. Then it can become a redundant diode to protect the cells. 

Wow now were cooking with crisco here ! Good thinkin fellas just for informational purposes I archived how to tin windows...

But I am all for application of balloon type material ...

Or maybe other things that don't involve a chemistry lab this is great thinking keep tinkering we will find something if we stick to it!

Simple brute force will find an array of things we can do with different payoffs obviously the holy grail is price per watt.
