There is currently one
solar powered light bulb for sale on the market, which is manufactured
The other type of solar light bulb is something which can easily be
made at home using a recycled plastic bottle. This invention, known as
a solar bottle bulb,
is the perfect DIY lighting solution and costs almost nothing to
Nokero Solar Light
solar powered light bulb was invented by Steve Katsaros in 2010 as a
way to allow people in developing countries to have light at night,
without the need to burn candles or kerosene. In fact, Nokero stands
for No Kerosene. Katsaros is hoping his lights will help people in
developing markets, and the majority of the bulbs that have been
purchased are for use in these poorer countries.
of the lights have been purchased by not for profit non-governmental
organizations to be given away in several different countries in
These light bulbs are
basically just small versions of a normal
solar light that are designed to be placed in the sun during the day
and then moved indoors at night to provide light.
will set you back around thirty dollars each. They are quite useful as
light for camping or any other indoor or outdoor illumination
Overall, this is a decent
product for the price and it should last for
years, although you’ll have to replace the battery every year or two.
How to Build Your Own
Solar Light Bulb
solar bottle bulb is a cheap and easy DIY solution for allowing more
light into darkened rooms during the day. Students at the Massachusetts
Institute of Technology originally came up with this concept of a solar
bottle bulb and the idea has been used in many countries around the
world, most notably in the Philippines and Brazil.
is actually quite a simple invention that uses a plastic bottle
containing liquid to refract light into a building, although it is
important to note that it will only provide light during the day when
the sun is shining on the bottle. The only downside to this particular
type of light is that it is necessary to cut a hole in your roof to
install it. Below are step by step instructions on how to build your own solar bottle bulb.
Materials You Will Need
to build your own solar bottle bulb
The first step is to fill the bottle about halfway with a mixture of
half bleach and half purified water. It is extremely important that you
use purified water, not tap water. The combination of bleach and
purified water will keep mold from growing and thus clouding the water,
which would make the light less effective.
1: Filling and sealing the bottle
This solution should last
for between two and five years before you will need to rinse out the
bottle and replace the solution. After filling your bottle with the
purified water/bleach solution, it is necessary to screw the
on the bottle as tightly as possible. You may even want to use glue or
any other sealant to ensure that air cannot get into the bottle.
Now you will need to cut a hole in your roof paneling that is equal
to the circumference of the bottle. Measure the circumference in the
middle of the bottle and then trace this out on your roof. It is
important to note that there must be direct access from the roof into
the room you wish to illuminate for this device to work.
what type of roofing material your structure has, it may be necessary
to use different methods for cutting the round hole in your roof. For
most types of roofing, it is recommended that you use a hole saw so
that the hole is cut perfectly round.
Now it is time to
insert the bottle filled with bleach solution into the hole you have
already cut in your roof. You should insert the bottle about halfway,
so that at least half of the bottle is inside the building. This will
allow the liquid solution to redirect the light directly into the room.
- Step 3: Inserting the
Finally, you will need to use
your roof sealant to completely seal
the roof around the bottle. This will help hold the bottle in place, as
well as preventing any leaks or rain dripping into your room. By
installing multiple solar bottle bulbs in your roof, you can completely
illuminate your room during the daytime and eliminate the need to use
electricity for lighting except at nighttime.
4: Sealing the hole in the roof
When the solution starts
to appear cloudy, then it is time to replace your bottle bulb. You will
need to extract it from the roof, and then you can either pour the
solution out and rinse the bottle, or you can build an entirely new
bulb from scratch.
is normally recommended to reuse the same bottle
to ensure that it will fit in the hole in your roof, just be sure to
rinse it thoroughly to prevent any mold or bacteria growth.
