Thats a kick ass schmidt cassegrain I would make a very nice scope with that . Someone stold my Mead 10 ” LX5 freaking thieves I hate them .
wtf ??? whre did you ge this hughe telescope mirrir and do you have any idea what such an miror is worth ? it hurts me to see it being used as an sun colector (i hope something is badly wrong with this mirror so it couldnt be used for an telescope anyway)
It is nearly perfect, there are some very very minor scuffs, I got all the finger prints off of it. This was for sale as a scrap item for $79:-)
0.o thahts awsome wehr did you get it ? probably you did the deal of yor life or this isnt actualy an real teleskope mirior (maybe it has some kind of an extrem destortion you wont even notice for such an use(telescope miriors have to be precicse to the scale of some nanometers))

This credit would benefit the owners of an S corp on their personal returns as their share of the credit would be passed to them on the Schedule K-1 that they would receive from the S corp.
In the case of a C corp, it would be a credit against their tax liability just like any credit.
As far as an LLC, the question doesn't make sense since the term LLC is an adjective describing the company – it is not a form of business in itself. In other words, and LLC could be a sole propriatorship, a partnership, an S Corp, or even a C Corp.
In a nutshell, this credit, like all credits, would benefit whoever pays the taxes of the business – the C corp itself, or the owner(s) or the sole proprietorship or partnership or S corp.

The last 2 comments are way off and a couple of idiots.. Those opinions are so so from a couple of people that can not see past the “notoriety” of her fame and really see the “Depth” of her images and the story the truly tell.. With one still image she really tells a persons story and personality like no other can. As well as the icing on the cake she makes that image a Grand Master Painting of a portrait. Those two I can tell have never seen her traveling “Gallery” of large original prints.
We are cleaning out our garage and don’t need these anymore: Old used downhill skiis two pair: Rossignol “Cut”, 170 cm, parabolic; Dynastar “Max” parabolic, 170 cm (no poles). 1 fiberglass child’s sled/toboggan, 1 “Zoomer” beach skimmer, 4′ high metal shelving unit (ok, but dirty, light rust), and some incomplete wall shelving materials as follows: Rails, 2 2 36″ long, Brackets to hold the rails, 6 deep and 8″ deep.
Call 643-7814 to arrange pick up. We are located on 24th Street near Dolores. I will be home all day today, Monday, 1/18.
I don't know if you are buying the right Fresnel lens. You need to determine the focal length you need for your application and the buy the right lens. Magnifying sheets are one kind of Fresnel, but not what you may need. On the other hand, the Fresnel lens on a light house would not work either but for the opposite reason.
Check with Edmonds Scientific and see what they have to say.

Wow! Technology finally is able to capture the sun’s potential. Will add to this comment later.

Lots of places sell them, in a variety of sizes. If you don't care how big it is, most book stores sell small ones (for reading small print) and you don't even have to go online.
But if you want to get it online, google shopping gives lots of places –

Well u really cant do any technologies easily because it would have to be a direct current device or else u would need an inverter which would change it to alternating current but those can be expensive and with a mini solar panel its not worth it. But a DS is direct current so thats not a problem u would probably want to get 2-4 mini panels with an output of 3 volts then put two in series if u only have two and if u have 4 then put two in series and then put those in parallel then u need to open the battery compartment and soder the red wires from the panels onto the positive of the battery then the black wires onto the negative of the battery then sucure the panels to the DS cover ie hot glue and if u have 4 panels then put two on the bottom two on the top and to charge it open up the DS in the sun

There should be a setting in the menu of the projector that'll flip the image being output. It'll either be 'Flip image' or 'Ceiling / Floor mount'.
depends on whether they’re smart or not
That would depend on the solar panel model and on the area in which they are deployed. Since these are of a relatively simple design (as apposed to the more common flat panels) and they are deployed in a desert, I’m quire sure they will more than make up for the energy it took to produce them.

Most good flashlights have parabolic reflectors behind the bulbs. This is because the parabolic shape forms a more or less coherent beam rather than let the light spread out as a sphere from the bulb. So there you are: three different sized flashlights.
i dont know why they allway use silver or aluminium as the reflector, brass is much more efficient … and you should paint the glass black if you want to heat something

the real question are you going to get past just talking
I like your system. Nice and simple, looks easy to recreate. My question is, why not plug your solar energy system into your house circuitry so you don’t have an extension cord to your kitchen and living room? Just throw the circuit breaker to the electric grid for when you don’t want to use the electrical grid, and disconnect your solar power when you use the electrical grid.
i want fresnel lens from where you bought that lens how much it costs please reply me i too use it for the projector purpose
I've seen some papers that have claimed that only the higher primates (i.e. chimps, gorillas, humans) have this ability – however, as you yourself have demonstrated, I have seen many other critters that allegedly don't have this ability display behaviour that indicates that they are also 'self-aware'.
One problem is that it's difficult to prove that if an animal reacts to a reflection, that it is because it realizes that the reflection is 'them' or not. Even more difficult is proving that an animal that doesn't react at all is not reacting because it realizes it's a reflection, or if it doesn't react because it just doesn't care.
- A solar radiometer will not be affected by the hemispherical location. It operates on absorption of light and conservation of momentum.
- If it makes you feel any better, the "water-direction reversal" is also a myth!
From wikipedia:
Crown glass was an early type of window glass. In this process, glass was blown into a "crown" or hollow globe. This was then flattened by reheating and spinning out the bowl-shaped piece of glass (bullion) into a flat disk by centrifugal force, up to 5 or 6 feet (1.5 to 1.8 meters) in diameter. The glass was then cut to the size required. Because of the manufacturing process, the best and thinnest glass is in a band at the edge of the disk, with the glass becoming thicker and more distorting towards the centre. Due to the distribution of the best glass, in order to fill large window spaces many small diamond shapes would be cut from the edge of the disk and these would be mounted into a lead lattice work and fitted in the window.
Crown glass was one of the two most common processes for making glass for windows up until the 19th century, the other was blown plate. The process was first perfected by French glassmakers in the 1320s, notably around Rouen. The process was kept a careful trade secret. As a result, crown glass was not made in London until 1678.
Crown glass is one of many types of hand-blown glass. Other methods include: broad sheet, blown plate, polished plate and cylinder blown sheet. These methods of manufacture lasted at least until the end of the 19th century. The early 20th century marks the move away from hand-blown to machine manufactured glass such as rolled plate, machine drawn cylinder sheet, flat drawn sheet, single and twin ground polished plate and float glass.
Crown glass is type of optical glass used in lenses and other optical components.
Crown glass is produced from alkali-lime silicates containing approximately 10% potassium oxide. It has low refractive index (≈1.52) and low dispersion (with Abbe numbers around 60).
As well as the specific material named "crown glass", there are other optical glasses with similar properties that are also called crown glasses. Generally, this is any glass with Abbe numbers in the range 50 to 85. For example, the borosilicate glass Schott BK7 is an extremely common crown glass, used in precision lenses. Borosilicates contain about 10% boric oxide, have good optical and mechanical characteristics, and are resistant to chemical and environmental damage.
Other additives used in crown glasses include zinc oxide, phosphorus pentoxide, barium oxide, and fluorite.

The Canon PowerShot S2 IS is a fixed lens bridge camera. The Canon EF f/4-5.6 75-300mm is an EF bayonet-mount lens for use with Canon's EOS SLRs and DSLRs.
The only type of lenses compatible with your S2 are conversion lenses. These are the add-on teleconverters, wide angle converters, and fisheye converters that screw onto the filter threads of your camera.
