Innovative bamboo bike design to charge your gadgets

World is a storehouse of energy. We all know that
energy can neither be created nor destroyed but can be transformed from one
form to another. But we are wasting resources that can produce energy as if
they are limitless. If we can renew and reuse the energy we waste, it would
help in some way to the problem of scarcity of energy, which is the major
threat of present world. Humans are able to generate approximately 150W of
power while riding bicycle. However, this power goes waste without any use. If
we can make use of this energy, we would be able to power many electronic
devices.
Here is the classic example of renewable energy source,
Bambootec consortium from Yucatan, state in the south of Mexico, designed a
bamboo bicycle that transforms the kinetic energy generated by pedaling into a
source of electricity that has the ability to simultaneously recharge mobile
devices, smartphone’s external battery and a navigation dashboard located on
the handlebars which measures the distance and time, and also has Bluetooth
connection.
The energy transfer is possible thanks to a converter,
which is composed of a circuit that starts on the rim, captures the kinetic energy
and converts it into electricity. After passing through the core of the system
located under the seat, which purpose is to regulate the voltage generated and
prevent discharges, said Cristina Espinosa Lopez, founder of Bambootec.
When pedaling, the cyclist produces energy that is
transformed into electricity. However, if done irregularly, by either
unexpected racing or braking, the load rises and falls; to solve this problem a
regulator was added to the converter to administer the charge evenly.
 
The new bike is made of bamboo and can transform
kinetic energy into electricity.
In addition to the power converter system, the bicycle
has a frame (vertices and edges) assembled with bamboo sticks connected by a
special resin. The aim was to replace metal parts for this natural material in
order to provide the vehicle with greater resistance (supports 120 kilos), also
making it lighter and less prone to heat, explained the founder of Bambootec.

                                       
Once the converter regulates the energy charge, this is
transmitted through three channels of power, which are cables with an USB
output. One is connected to the navigation screen located on the handlebars of
the bicycle, which indicates the number of kilometers and time passed, and
provides the option to establish a connection via Bluetooth to link to a
smartphone. The other terminal of the power converter recharges any mobile
device, while the third one is exclusive to recharge smartphone’s external
batteries. It is important to highlight that the energy generated by the
bicycle (over 10 volts) is enough to feed the three tracks simultaneously, Espinosa
specified.
Currently, bicycle testing has shown that the charge
capacity for the devices is of one percent per minute. It is required to optimize
the system in order to accelerate the charging process. The team has as a main
goal to create the necessary machinery to scale the product and mass produce
it; because of this, the company participated in the Cleantech Challenge Mexico,
a contest that promotes the development of green enterprises.

There are various renewable energy sources such solar,
wind, hydropower etc. In addition, people use fossil fuels, which are
non-renewable. These resources are very expensive. Therefore, there is a need
for cheap, renewable energy source. As long as we are pedaling and the system
is working fine, we can get the power whenever needed. Power generation using
bicycle is very cheap and eco-friendly.
