2. Energy
With energy prices on the rise and antique power grids
patched together with gum and twine, it's time to take some
control and get serious about reducing your use of the juice.
Everyday lots and lots of energy is getting wasted and we
need to take innovative action to conserve energy for our
future generation.
There are a lot innovative research going on for conserving
energy. In this presentation we are
going to discuss a few amazing
innovative methods to conserve
energy.

3. Thermoelectric Paint
In the ongoing crusade to discover alternative
forms of electrical energy, paint was no doubt low
on the list of possible candidates. But experts at
the Ulsan Institute of Science and Technology saw
unexplored potential in this material. The have
designed and developed thermoelectric paint,
which absorbs waste heat energy from buildings
and converts it into electric power.

4. How Thermoelectric Paint Works?
The thermoelectric paint contains the thermoelectric particles bismuth
telluride (Bi2Te3), which are commonly used in conventional thermoelectric
devices. The researchers also added molecular sintering aids which, upon
heating, cause the thermoelectric particles to coalesce, increasing the density
of these particles in the paint along with their energy conversion efficiency (the
ZT values are up to 0.67 for n-type and 1.21 for p-type particles). The
researchers demonstrated that the thermoelectric paint can be painted onto a
variety of curved heat-emitting surfaces. After sintering for 10 minutes at 450
°C, the painted layers form a uniform film about 50 micrometers thick.
Tests showed that the devices painted with the thermoelectric paint
exhibit a high output power density (4 mW/cm2 for in-plane type devices and
26.3 mW/cm2 for through-plane type devices). These values are competitive
with conventional thermoelectric materials and better than all thermoelectric
devices based on inks and pastes.

5. Incineration
Incineration is a waste treatment process that involves the
combustion of organic substances contained in waste
materials. Incineration and other high-temperature waste
treatment systems are described as "thermal treatment".
Incineration of waste materials converts the waste into ash,
flue gas, and heat.

6. How Incineration works?
Incinerators use heat created by the combustion of fuels in order to dispose of waste
products. Heat created during the waste disposal process is also used to power steam-
driven electrical turbines, and the remaining ash is then transported to a landfill.
Facilities that make use of an incinerator must first sort the waste
materials that have been transported to the site. Materials are typically sorted
through use of an overhead crane and then placed within the incinerator's
combustion chamber. Waste heat produced by the combustion of both fuel and waste
products is captured and used to convert water into steam, which is then used to
generate electrical power. Emissions from the combustion process are captured by a
high-efficiency filtration system, and residual ash is collected and packaged before
being transported to a landfill by covered leak-proof trucks.
The first waste-disposing incinerator to be built in the United States
was constructed in 1885. Early incinerators were constructed and put into operation
before their impact on the environment was fully understood. Today, residual waste
metals that survive the combustion process are typically collected for recycling, and
the current generation of incinerators operate within a strict set of guidelines
regarding particulate emissions and water discharge that may cause ecological harm.
