　　Since we've been discussing alternative fuels lately, I wanted to pass on to you some information I read about a new fuel that's been in the news a lot lately. It's called A-21. It's composed of water and a chemical known as naphtha. It seems to be a very promising fuel because it's much cleaner than the gasoline that we use today. That's not to say that it doesn't pollute, but it is cleaner. A-21 isn't like some other alternative fuels that require completely new types of engines. A-21 still works in regular, everyday combustion engines—like the ones in cars—with only minor mechanical modifications. So changing over wouldn't be a big deal. You may doubt some of these claims as many researchers have. Some people feared that because it contains about 45 percent water it would freeze in the winter. But a small amount of antifreeze was added to it, and that seems to have solved the problem. A-21 has recently undergone street tests in buses in Reno, Nevada. So far it seems to work just fine. This is a good thing, especially in Nevada, because the state government there has passed a law requiring that a large percentage of vehicles in Nevada run on alternative fuels. A-21 should help.

　　Today we're going to continue our discussion of modern art and talk about Charles Csuri. Charles Csuri has been a part of many modern art movements. He's worked in Pop Art, Cubism, and Conceptual Art, but he made his mark as a pioneer in computer art. Even long before computers became popular, he was punching cards and feeding them into the big mainframe computer at Ohio State University. In the beginning, he had to work without a monitor, so he was virtually creating art in the dark. He even learned computer programming so he could experiment with this new tool. Through the computer, Csuri has been able to explore a new world of possibilities. For example, the computer enables him to sculpt in three dimensions. Also, he can look at a sculpture from any angle, and move it around, change the location of the light source, or he can copy it in different colors. Over the years, Csuri received numerous grants for various projects. This money allowed him to train students in computer graphics and animation techniques, and to advance the computer as a medium for artists. Even though he uses modern technology, Csuri still insists he is creating art. He's always told his students to keep the issues of art in focus, and not get so caught up in the technology that you forget about the image.
