In recent years, automotive companies have tried to implement in their vehicles devices that supply renewable energy to the electromechanical systems that make them up, giving rise to well know hybrid and electric cars. The main idea to produce this kind of energy is focused on taking advantage of resources that in the past were useless due to the lack of technology. This work presents a preliminary system of electrical charge from the use of sun heat that is stored in the front panel of the car while it is parked in such a way that the solar radiation falls directly on it. The system uses inversely a Peltier cell, an electronic element that is composed of plates of semiconductor material that has the property of generating heat or cold depending on the polarity that is applied to the plates, for this case one of the cell faces is used to capture the heat energy through the vehicle front windshield. This work presents a system of heat conversion in electrical energy using a Peltier cell, preliminary experimental results obtained are discussed.

It have been proposed different solutions to the problem of gas leak detection one being the use of mobile systems. An autonomous system equipped with a gas sensor (ethanol) and controlled by a microcontroller and an algorithm designed to follow the trace of smell in terms of concentration that existed in the place of taking the reading by the sensor built without considering brownouts only taken the arrangement proposed by the sensor, thus the location of the source is made and direct the system directly. In this paper the results of location system made in different workspaces, focusing primarily on the acquisition of sensor data with an analog-digital conversion 10 bits are presented whose resolution would be 4.8 mV per bit against the standard 19 mV commercial resolution. Experimental results and analytic explanation is showed below.
