liquid level Alarm
Here is a simple circuit for Liquid level alarm. It is built Around two BC547 transistors(T1 and T2) and two timer 555 ICs (IC1and IC2). Both IC1 and IC2 are wired in astable multivibrator mode. TimerIC1 produces low frequency, while timer IC2 produces high frequency. As a result, a beeping tone is generated when the liquid tank is full. Initially, when the tank is empty, transistor T1 does not conduct. Consequently, transistor T2 conducts and pin 4 of IC1 is low. This low voltage disables IC1 and it does ....etc

The reason why electric cars aren™t everywhere is simple ” at the end of their range, they have to be stationary for hours while the batteries are recharged.

This is a pity, because even cars recharged from Ëœdirtyâ„¢ power stations are three times more environmentally friendly than conventional vehicles. Thatâ„¢s because only 20 per cent of the energy from gasoline or diesel actually reaches the wheels; in an electric car, itâ„¢s 60 per cent.

TITLE :LIQUID NITROGEN AS A NON- POLLUTING FUEL
ABSTRACT:
Our paper examines the capability of several energy conversion process to provide sufficient energy in a world where the non-renewable resource are getting depleted. Moreover pollution caused by them is increasing at a rapid rate. One such efficient and non-polluting means of running the vehicles is the use of liquid nitrogen. To use liquid nitrogen as a non-polluting fuel, a multiple reheat open Rankine and a closed Brayton cycle are used.

Abstract:
reflective cholesteric liquid crystal displays (Ch-LCDs) because they are lightweight, low power flat-panel displays. Furthermore, Ch-LCDs can be made bistable which allows for the manufacture of large area, high- resolution displays without the need for expensive, difficult to manufacture active matrix addressing schemes. Also, the bistability enables flicker-free operation. Currently, these displays are made using glass substrates. However, some applications require rugged (i.e., nonbreakable), flexible displays. The use of a plas ....etc

Liquid electricity is a fictional liquid substance that often appeared in comedy short films of the silent film era. It is the distilled essence of electricity in liquid form, a (usually) glowing substance easily stored in bottles. It provides fantastic energy and super-speed when used as a fuel for automobiles, aircraft, and machines of all sorts. One variant of liquid electricity could be drunk by humans, who often did so for comedic effect in silent film comedies. The use of liquid electricity as a comedic plot device was often used by f ....etc
