Well, probably such situations are not that common, unless you love hiking in unknown forests and part of your adventure is getting lost at night, or you live in a place where power cuts never occur, hence you are never prepared for such incidents. But Instructables member ASCAS came up with a small device that can provide light only by adding water to it, and help you find your way to salvation no matter what the situation is.

The miracle self-made super green device is a flashlight powered entirely by water. Not only it can never run out of battery, simply because water is everywhere, but it also does not pollute the environment with toxic chemicals associated with conventional energy storage devices.

Now that the pipe is nicely closed on one side, bring it to the tap and fill it up. You can use other liquids too, not only the tap water, which could provide only half an hour of light. Salt water is rich in electrolytes and allows you to use the flashlight for up to 2 hours, but if you pick something like vinegar or gatorade, you might be able to enjoy it for as long as 10 hours.

During a power outage, you may be left without heating/air conditioning, lighting, hot water, or even running water. If you only have a cordless phone, you will also be left without phone service. If you do not have a battery-powered or crank radio, you may have no way of monitoring news broadcasts. In other words, you could be facing major challenges. Everyone has a responsibility to protect their homes and their families.

Start by discussing what could happen and what you should do at home, at school or at work if an emergency happens. To be prepared, make a list of what needs to be done ahead of time. Store important family documents, such as birth certificates, passports, wills, financial documents, insurance policies, etc. in waterproof container(s). Identify an appropriate out-of-town contact that can act as a central point of contact in an emergency.

You may have some of the items already, such as a flashlight, battery-operated radio, food, and water. The key is to make sure they are organized and easy to find. Would you be able to find your flashlight in the dark?

It's powered by a water-activated fuel cell and it seems simple: twist off the bottom and remove the fuel cell. Then immerse it in water for about ten seconds to generate power, shake out the water, then put the fuel cell back into the Hydralight.

The flashlight runs 30 minutes continuously with tap water and 2 hours with saltwater. Not bad for a single celled prototype. This thing also works well with calculators, clocks & radios. Remember, adding a second cell triples the glow and lighting time!

Another location would be the famous Sea of Tranquility (Mare Tranquillitatis), where Apollo 11 first touched down on the Moon. It has plenty of exposed rock strata that could provide insights into the geological formation of the Moon. However, they are only accessible by dangerous terrain that would be difficult for any rover to traverse. Hitting them with an EmberCore flashlight would allow a rover to observe them remotely without making the tricky trek to get to them.

Flashlights can get very expensive, so for a light powered by two AA batteries, we set a price limit of about $40. There is an enormous world of flashlights that cost more, but at this price, we knew we could find an entry-level version of an enthusiast light that offered some of the most important features standard on the higher-end lights. Unfortunately, our cutoff excluded many manufacturers that were favorites of the flashlight crowd (as well as among police officers, firefighters, and others in public safety), notably Elzetta, Fenix, Foursevens, and SureFire.

Instead of taking more meter readings in a sealed, lab-like, dark room, I spent night after night after night wandering around the dark New Hampshire woods (and more than once caught the reflection of animal eyes looking back at me). We tested in the weeks surrounding a new moon and in an area with very little light pollution. This unstructured testing gave us the most useful gauge of overall usability, beam spread, and beam distance, and it really helped us understand what each light had to offer from a practical standpoint. We also used the flashlights for more regular daily tasks, such as looking under the couch for Legos, checking the crawl space for signs of mice, and investigating strange nighttime noises in the backyard. Lastly, we used the lights during multiple power outages.

Speaking of drops, the Archer 2A V3 is rated for a 1-meter fall. Many flashlights we tested also came with an IPX rating indicating the standard for protection against water intrusion. The Archer 2A V3 has the highest rating of IPX8, meaning it can tolerate being completely submerged in water over 2 meters deep (which we put it through a number of times to no ill effect). The tested lights from Manker and Nitecore have the same water-intrusion rating as this ThruNite model.

The E12 has the same two-button interface with four brightness levels and a hidden strobe function. It has a memory like the Archer 2A V3, as well as the same momentary-on feature. It also has a similar high-quality look and feel, including a knurled body, an anti-roll design, and the ability to stand on its tail. We like that the Manker is about inch shorter than the ThruNite and that the pocket clip has a little more heft. Manker says the E12 has a rating of IPX8; this means it has the same waterproof ability as the Archer 2A V3.

With this setup, we found it very easy to regularly keep the Olight fully charged. All we had to do was set the light down right near the charging cord, and it would attach itself. Additionally, we were impressed with the overall feel and quality of the S2R Baton II. It typically costs around $70, which is still less than the price of most quality rechargeable flashlights.

The Olight Warrior Mini 2 is an excellent light and has the interesting ability to auto-dim if an object is too close to the lens, to prevent overheating in a backpack or a pocket. Typically $20 more expensive than the Olight S2R Baton II, this model is brighter and offers a longer battery life. It has both a side button and a tail switch, which control different settings and can get confusing. If you use a flashlight enough to keep these button modes top of mind, this light provides a lot of versatility. During more casual use in our tests, however, we kept forgetting the nuances of the buttons and often ended up grabbing another flashlight with a simpler interface.

Please reach out to our team at support@survivalfrog.com if your HydraLight does not work after 10 hours and we will get you taken care of.

Thanks for sharing your feedback. I am glad you've enjoyed using your HydraLight. As stated on our website, " After 10 hours, just re dip in water and it comes back to life." So, yes, it is reusable. Thanks for your support!

A flashlight can be used to see in the dark regions of the moon to better understand what those areas are composed of. Such a new project recently received funding from a NASA Institute for Advanced Concepts (NIAC) Phase I award.

The technology is still being tested, but NASA saw its potential. By slightly modifying EmberCore, the x-ray and gamma-ray flashlight mounted on some kind of rover can be produced, which would have a beam strength orders of magnitude greater than what has been previously deployed in space. This intensity provides a significant source of light that will be able to travel over many kilometers, interact with the ground, and then bounce back toward a special sensor.

The signal that is returned to the sensor is like a fingerprint that can be used to identify substances such as water. Because the flashlight uses X- and gamma rays that penetrate the surface, information will be revealed about not just the surface but what lies beneath the surface.

The Water Powred Torch uses NoPoPo hydrogen power (water) batteries and is simple to use and can be recharged almost anywhere. and is good for the environment as well. The batteries can last up to ten years with recharge and without losing capability to recharge.

A flashlight (US, CA) or torch (UK, AU) is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the mid-2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch, all enclosed in a case. 041b061a72
