Answer by TechwingYou need something like carbon-arc-welding glasses in order to view this type of eclipse safely. They should be at least shade #14.
You could photograph it with a digital camera as long as the camera has an electronic viewfinder and not an optical viewfinder. However, this may permanently damage the camera.
Another good way to see the eclipse is by using a special solar attachment on a telescope that projects an image of the sun onto a screen (NOT by looking directly into the telescope, which will produce blindness).
Sunglasses are not dark enough to help.
The only solar eclipses that can be safely viewed with the naked eye are total solar eclipses, when the sun is completely covered. This is not that type of eclipse. The sun's edge will still be visible during this eclipse, which makes it dangerous to look at with the naked eye. It also makes the eclipse far less impressive, since it doesn't get very dark and the portion of the sun that is visible is so bright that it makes everything else invisible.
My own opinion is that only a total solar eclipse is worth getting excited over. Partial and annular eclipses are a disappointment, as well as an eye hazard.

How to safely look at a solar eclipse?
Can Staring at an Eclipse Really make you go Blind?
Question by Malevolence: Can Staring at an Eclipse Really make you go Blind?
Can it make you go blind or just hurt your eyes? Temporary blindness or permanent? And can video taping an Eclipse, looking at the eclipse through a camera lense blind you aswell?

Answer by Guru HankPERMANENT.
Even after a very short exposure, and even when the eclipse is near total. There have been mass tragedies following some eclipses in parts of the world where this was not widely understood. You might not notice the damage has occurred until later. It would then be too late. Never look at the sun directly even part of it, for an instant.
Make a tiny pinhole in a piece of black card, and WITH YOUR BACK TO THE SUN project the light which shines through this onto another piece of card. You will get an image of the solar eclipse as it occurs. Do not risk messing around with bits of 'smoked glass' and other gimmicks like some teachers did with a class when I was a kid. You always end up getting a dangerous exposure.

Is there anyone trying to create a cheaper and more efficient solar panel?
Question by Estr Bien Cvzoch: Is there anyone trying to create a cheaper and more efficient solar panel?
I read on CNN's website last year some company was creating a very cheap type of solar panel, that needs minimal maintenance and and has minimal glare from the sun. And the creator of the project said he one day wanted to cover every rooftop in the US with these solar panels. Seems like a good idea to me but I havent heared anything of it for a long time and I don't know what they are called... any help?

Answer by Dominic Fno i havent heard of it but domestic solar energy is new and as the demand for it increases and the technology becomes more easily to produce the price will come down. just like tv,mobile phones, computers and appliances.

At the solar industry's largest event, Intersolar Europe, 2011 SunPower launched its new 96-cell E20 modules, which are the industry's first commercially-available solar panels to achieve total area efficiencies of 20% and above. Jorn Jugens, SunPower's managing director, Germany had the honour of discussing with PV-Tech the key characteristics of the module, which includes SunPower's 22.4% efficient 'Maxeon' cell technology. The modules will be offered in Europe and Australia this year, with availability extended in North America and Asia in early 2012. All of SunPowers production lines will be transferred to the new Maxeon cell process by mid-next year.
