How about a glowing light source that lasts for 15 years instead of the typical 15 minutes of a glowstick? GlowPaint’s newest product does just that and is also non-toxic and inexpensive and doesn’t require a recharge via solar or electrical sources for its entire lifespan. According to the company, “This has potential to save billions in energy costs world-wide. Litroenergy™ surpasses all known available lighting options for cost/durability/reliability and safety.” Their products are expected to be used to replace other forms of safety, emergency and novelty lighting duties normally performed by glow sticks, LEDs and other light sources.
