Scientists from the Metropolitan Autonomous University of Mexico are putting the final touches on the first fluorescent light that is free of environmentally harmful gases and powders. This year, after seven years of research, the invention and the patent on the process will be ready, María Luisa Ojeda, a member of the team of scientists involved, told Tierramérica.

The white fluorescent lights used widely today contain mercury, which when released into the environment cause serious contamination problems. The Mexican invention uses a harmless compound of aluminum and silicon, she explained.

It is hoped that this new lightbulb will be used around the world, eliminating the contamination associated with the existing fluorescent bulbs when broken or disposed of.
