Support Refhub: Together for Knowledge and Culture

Dear friends,

As you know, Refhub.ir has always been a valuable resource for accessing free and legal books, striving to make knowledge and culture available to everyone. However, due to the current situation and the ongoing war between Iran and Israel, we are facing significant challenges in maintaining our infrastructure and services.

Unfortunately, with the onset of this conflict, our revenue streams have been severely impacted, and we can no longer cover the costs of servers, developers, and storage space. We need your support to continue our activities and develop a free and efficient AI-powered e-reader for you.

To overcome this crisis, we need to raise approximately $5,000. Every user can help us with a minimum of just $1. If we are unable to gather this amount within the next two months, we will be forced to shut down our servers permanently.

Your contributions can make a significant difference in helping us get through this difficult time and continue to serve you. Your support means the world to us, and every donation, big or small, can have a significant impact on our ability to continue our mission.

You can help us through the cryptocurrency payment gateway available on our website. Every step you take is a step towards expanding knowledge and culture.

Thank you so much for your support,

The Refhub Team

EmDrive provides a comprehensive description of the theoretical background of this emerging technology. It includes the derivation of the essential equations, provides full thruster design details, and describes the manufacture and methods of testing that would enable the work to be correctly reproduced in the appropriate research facilities.Electromagnetic drive is a proposed method of propulsion that does not require a propellant, although it still requires fuel. It holds the potential to revolutionize renewable energy production, clean and quiet transport, and global climate control. Having evolved from numerous individual and organizational contributions, this book explains the origin and subsequent development of this theory from the original UK government requirement. The sequence of experimental devices is covered in detail, and the subsequent test results are discussed. Similar programmes in the USA and China are introduced, and the implications of recent disclosures are considered.This book will interest industry professionals working on electromagnetic theory and experimental physics in the fields of aerospace and energy engineering.
