cylonlover writes "A new manufacturing method that incorporates laser technology may result in thin film solar panels that are less expensive and more efficient than anything presently on the market. Currently, a stylus is used to mechanically etch microchannels into such panels, which electrically connect the individual solar cells and allow them to form an array. Researchers from Indiana's Purdue University, however, are developing a technique in which an ultrafast pulsing laser is used to do the etching. Not only will it hopefully be quicker and cheaper than mechanical 'scribing,' but it should also produce cleaner, sharper microchannels that offer superior performance."
Humanity has the stars in its future, and that future is too important to be
lost under the burden of juvenile folly and ignorant superstition.
