High-Level Project Summary
The temperature on Venus's surface exceeds 475 degrees Celsius. We took advantage of this fact by using this extensive heat to power a series of 10 thermoelectric generators. A thermoelectric generator (TEG) is a device that uses the temperature difference between its two sides to move the electrons which generates electricity. In our case, the hot side will be directly exposed to Venus's atmosphere, while the other side will be cooled using a water cooling system. We will store this electricity in a lithium-ion battery making a complete energy production/storage system which depends completely on natural sources that can solve our challenge and power up the rover for 60 days straight.

Detailed Project Description
we try to develop energy storage and production system that powers a rover on the surface of Venus for 60 days. The system mainly depends on generating electricity from 10 generators called Thermoelectric generators. A TEG is a solid-state semiconductor device that converts the temperature difference between two of its sides into a valuable DC power source. The Hot sides of the generators will be exposed to Venus's hot atmosphere, which can reach up to more than 475 degrees Celsius. The cold sides of the generators will be isolated from the outer environment and cooled by a water-cooling system that is preserved cold by insulating mineral wool that can insulate up to 649 degrees Celsius. The cold side will be cooled up by pumping continuous cooled water to it by using a water pump to reach 5 degrees Celsius, giving a temperature difference of 470 degrees Celsius. According to the Carnot efficiency equation, the generators are expected to reach up to 60% of efficiency and generate up to 150 watts. The generated power will then be stored in a lithium-ion battery that is preserved safely inside the isolated system.
In order to illustrate the design of the project we used the blender 3D modeling tool and made a 3D model of the project which helped us better understand it and make better decisions overall.
Space Agency Data
We used the following link to gather information about venus like the Temperature and Venus's atmosphere composition.

Hackathon Journey
Participating in Nasa space apps Benha is one of the best decision we ever made. The hackathon is not just about co-operating to finish our project. However, it strengthened may significant skills that ca e extremely benefit us I our whole life such as time management, scientific research, leadership skills, ad more. It also gave us the chance to tur our ideas which were nothing more than dreams,
