A 15 Year Old Has Invented A Flashlight That Runs Off Your Hands
If that headline made you feel like you may not be contributing as much effort to society as you could…you’re not alone.
Yes, a 15 year old from Canada has created a flashlight that runs off of nothing more than your hands. While you might guess that magic is the cause (possibly evil magic) it in fact functions because of peltier tiles, which generate an electric currency when one side of the tile becomes hotter than the other.
In this case, the exterior of the handle is heated by your hands, while the interior components remain cool. Specifically, the exterior must remain 5 degrees Celsius hotter than the interior for a useful enough current to be produced.
The developer calls this the design’s greatest flaw, since being humble is much easier when you are a 15 year old genius.
Dubbed the hollow flashlight because of its hollow handle, the design is still in a sort of prototype phase and is currently making its rounds at various young achievers contests, including the worldwide 2013 Google Science Fair, where it finished in the top 15.
Garnering impressive accomplishments aside, there doesn’t seem to be much direction for the hollow flashlight as there is only the one known model and, no matter how intelligent they are, 15 year olds usually don’t mass produce on their own.
This is a great design, though, that improves upon some recent battery free flashlight ideas, by functioning off something you always have easily on hand (pun sadly intended) without relying on cumbersome and time consuming mechanics.
Hopefully then someone picks up the concept, as some form of this design would ideally be in every emergency kit worldwide.

What Is Hydroquinone?
Hydroquinone is a derivative of benzene, often used as a skin lightening agent.
It is commonly found in over-the-counter creams and serums, typically to treat conditions like sunspots, age spots, and
hyperpigmentation. Hydroquinone works by inhibiting the production of
melanin, the pigment responsible for dark spots and uneven skin tone.
Benefits of Hydroquinone for Skin
Certain individuals experience significant benefits from using hydroquinone.
These include:
– Treating Sunspots: It helps fade discoloration caused by prolonged sun exposure.
– Reducing Hyperpigmentation: It can lighten areas of skin that are darker than the rest, such as
those affected by melasma or post-inflammatory hypopigmentation.
– Brightening Skin Tone: It is sometimes used to achieve a more even and lighter complexion, though it should be used with caution due to its potential for side effects.
Is Hydroquinone Safe? What You Need to Know, According to
Derms
The safety of hydroquinone has been a topic of debate among dermatologists and regulators.
While it is effective, studies have raised concerns about its long-term use and potential to
cause harm. Here’s what you should know:
– Potential Risks: Long-term use or misuse can lead to complications like liver
damage, thyroid disorders, and even cancer in some cases.
– Regulatory Status: In recent years, hydroquinone has been restricted or banned in several countries, including the EU and parts of
Asia, due to these safety concerns. In the U.S., it is still available but often requires
a prescription for certain conditions.
– Expert Opinions: Many dermatologists recommend using hydroquinone only under medical supervision and for short periods,
as the risk-benefit ratio may not justify long-term use for aesthetic purposes.
Side Effects of Hydroquinone
While hydroquinone can be beneficial, it is not without
risks. Common side effects include:
– Mild Skin Irritation: It can cause redness, dryness, or peeling in the area where it is applied.
– Discoloration: In rare cases, it may lead to a temporary lightening of existing dark spots while
potentially causing new discoloration elsewhere on the
skin.
– More Severe Reactions: In some individuals, hydroquinone can cause allergic
reactions or trigger conditions like acne or rosacea.
How to Use It
For safe and effective use, follow these guidelines:
– Apply as Directed: Always follow the instructions provided
on the product label or by your healthcare provider.
– Test a Small Area First: Before applying hydroquinone to larger areas of skin, test it on a small patch to ensure you are not allergic to
it.
– Avoid Overuse: Do not use hydroquinone in excess, as this can increase the risk of
side effects.
– Store Properly: Keep the product out of reach of children and store it in a secure location.
Must Watch
Beware of these important considerations when using hydroquinone:
– Consult a Doctor First: Only use hydroquinone under medical advice, especially if you
have a history of liver or thyroid issues.
– Avoid Combination Use: Do not mix hydroquinone with other depigmenting agents unless directed by a
professional.
– Do Not Use Long-Term Without Guidance: The long-term safety of hydroquinone remains uncertain, so it should not be used continuously
for years without medical supervision.

considerably elevated testosterone level in arsenic-induced reproductive harm in rats [47].
In addition, quercetin at 90 mg−1 kg−1 day−1 for 15 days was found to
boost testosterone manufacturing in male rats with
di-(2-ethylhexyl) phthalate-induced reproductive toxicity [48].
Moreover, adult male albino rats with atrazine-induced reproductive toxicity administered quercetin at 10 mg−1 kg−1 of body weight for 21 days had greater ranges of testosterone compared with the
control [49].
In addition to nitric oxide, onions are additionally stuffed with antioxidants, that are helpful for maintaining your total well being.
The researchers suspect that the antioxidants in query are probably selenium compounds found in onions, and phenols similar to quercetin and isorhamnetin. Isorhamnetin can also be
