The solar heater is a device for converting solar radiation #energy into #thermal energy used in heating #water for home purposes and warming .

The #solar #heater consists of the following sections: #Storage tank – Sun ray collector – Accessories
Aluminum Extrusion is a process of production by forming objects with a fixed section by pushing the material to be formed through a slot with a specific shape so the material
section takes the shape of the hole, the features of this process is getting a complex forms of the section of the material produced and the ability to form materials
Solar Tower is an important effective way to use #solar #power
It consists of a mirrors array field called “heliostat” that reflects sun rays to the receiver at the tower ,
The collected rays heats up the heat transporter ,we use melted
salt that filled in tanks to be used at the night .
The Wankel #engine is a type of internal #combustion engine using an eccentric rotary design to convert #pressure into rotating motion.
In contrast to the more common reciprocating piston designs,the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio ;
How planes fly ? Plane Wing works ?
A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky. So it’s the engines that move a plane forward, while the wings move it upward.
