Saltwater-Powered Lanterns

Clean the Sky - Positive Eco Trends & Breakthroughs

The Hydra-Light PL-500 Lantern is Powered By Saltwater

— February 2, 2016 — Eco
The Hydra-Light PL-500 is a high-tech personal lantern that is powered by fuel cells rather than conventional sources of portable energy.

This lantern's heart is comprised of a carbon film cathode and a special high energy-density alloy anode. When exposed to salt water, the anode begins to oxidize, causing it to release electrical current that can be exploited as a source of energy. The anode works with seawater or even water mixed with regular table salt.

The problem with regular lanterns is that you tend not to use them often, but they are prone to being drained of battery or power just when you need to use them. The Hydra-Light PL-500 gets around this problem with its use of salt water, ensuring you always have peace of mind and aren't left in the dark about your lantern's usability.


Trend Themes
1. Saltwater-powered Technology - Disruptive innovation opportunity for companies seeking alternative and sustainable energy sources.
2. Fuel Cell Power Generation - Opportunities for companies to develop products that harness the power of fuel cell technology.
3. Sustainable Energy Solutions - Innovation opportunity for companies seeking to reduce their carbon footprint and offer eco-friendly solutions to consumers.
Industry Implications
1. Outdoor Gear and Equipment - Opportunities for companies in the camping and hiking industry to offer saltwater-powered innovations to outdoor enthusiasts.
2. Emergency Preparedness - Innovation opportunity for companies in the emergency preparedness industry to offer saltwater-powered lanterns as a reliable and sustainable source of light.
3. Renewable Energy - Opportunities for companies in the renewable energy industry to explore fuel cell technology as a potential source of sustainable energy.
