Thats because its too expensive to string power lines3 to the remote mountain areas where they live. To help support themselves,the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. And without electricity一at home or on the road,they can only work during daylight hours. When it gets dark,they must stop whatever theyre doing. Now，a team of scientists，designers, and architects is using4 new technologies to provide the Huichol with light after the sun sets. The scientists technique involves weaving tiny electronic crystals into fabrics that can be made into clothes,bags,or other items. By collecting the suns energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics ” Portable Lights. ” Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy. “ Our invention，” Kennedy says，“ came from seeing how we could transform technology we saw every day in the United States and move it into new markets for people who didnt have a lot of money. ” At the core of5 Portable Light technology are devices called high-brightness light-emitting diodes,or HB LEDs6. These tiny lights appear in digital clocks,televisions,and streetlights. LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give off light we can see. Ninety percent of energy produced by incandescent ligh
