Invisible solar roof

Invisible solar roof
The future world will be electrified with the help of renewable energy sources. One such in exhaustible energy source is solar energy. Now a days, solar panels have been replacing the conventional energy for electrifying any of the electrical appliances. Though it is not accepted all the people due to its high cost, many people are changing their taste to solar powered home or vehicles. In this connection, if any home is powered with solar energy, i will be distinguishably visible to all that the house is using the solar energy or power.
Because the solar panels are visible over the roof. In modern technology in the solar energy era has changed its design in such a way that the solar panels are invisibe, on the other hand i can state that it is integrated within the roof itself. This is what shown in the figure. Hence, no one can identify whether that particular house is backed with solar energy. What a great technology revolution?

Novel Engineering projects from electrofriends

Novel Engineering projects from electrofriends
Final students are in hunting of their engineering projects. Novel projects in different areas are required for them. Electrofriends is one such website where plenty of engineering projects are available.

The project list varies from microcontroller based projects to computer oriented control. Few of the projects are vehicle monitoring and safety, robotic car controlled by 8951 micro controller, solar tracking system, Intelligent train engines, Digital IC tester. Even this site includes some famous C++ programming based project. Sudoku using C++ coding is very interesting puzzle to solve.
One important thing is that we can submit our own engineering projects. Really a lot of collections of projects are available.

Automatic Energy Meter Reading through Power Line Communication

Automatic Energy Meter Reading through Power Line Communication(PLC)

In most of the places in world wide, Energy Meter reading is done through nominated officials by visiting the residential and commercial places. In this technique, it is proposed to change the existing energy metering by employing the Power line communication technology. Power line carrier communications take place over the same lines that deliver electricity.

This technique involves injecting a high frequency AC carrier into the power line and modulating this carrier with data originating from the remote meter or central station. Power Line Communications transmits data over an existing high voltage power line instead of requiring dedicated cabling. PLC can thus provide an inexpensive solution for transmitting data in a pre wired location.
The solution for residential Automatic Meter Reading (AMR) consists of a host computer, a gateway interface and a low-cost Power Line Carrier (PLC) residential meter. LCD display showing the meter readings, date of bill payment and billing details. The system also incorporates a power cut feature, which can be activated when the consumer doesn’t pay the bill within the due date. The system performances become superior to conventional methods. Now this scheme becomes implementing able with advent fast computing devices.
