These days, companies all over are trying to use solar power to save money and help the environment. A group of scientists from Columbia's Computer Vision Laboratory designed a video camera that runs off of the same light as a photo camera. That means no more charging a camera battery. The reason why this video camera works is because it has photodiodes. Photodiodes take the light and turn it into electricity. Normally, only a digital camera has photodiodes, but scientist figured out a way to put it into a video camera.
The outcome of the video is not at all perfect. The video is 30 by 40 pixels, which turns out to be very blurry. Today quality movie pictures have millions of pixels that is why it is so clear and crisp. This video camera does not have any color, meaning it can only be produced in black and white. Also the camera isn't the most small and compact item in the media world. It looks like an old, boxy camera from back in the day. All of these problems can be fixed easily if there wasn't a budget for the college, and if more people and or companies wanted to get involved with this product. A great quality to this new video camera is that it is cheaper for most people. With cheaper cameras more people can buy them. They can buy them not only for recreational activities, but for surveillance too. This innovation can help families stay more safe. I think this is a really good innovation, not only for the environment but for the people too. In this case it is a win win situation for everyone. I do not like how the camera is super big and hard to take around anywhere, but overtime I think the scientists will think of ways to make it smaller. Also I feel like this video camera is going to have a hard time selling if the picture quality is looking the way it is. Overall, I think this new video camera could have a big helpful impact in the media world, if some adjustments were made. http://www.wsj.com/articles/a-video-camera-that-runs-on-light-1429302199
