Zero Level Energy

As a result of a giant solar flare, the air of the Earth became temporarily toxic. With the powerful solar storms, particles are released into the atmosphere, which kill immediately in the lungs. You're in an underground bunker for the most critical days, where a supercomputer ensures the conditions for living. In the past few days, the outdoor instruments have signaled that the air is clear again, but you have not received any information on how to get out of the bunker that you've been living in life so far. This is also a big problem because the bunker wins its energy from its own energy storage, but now the power plants are almost completely depleted. Since the air supply and the exit door are also controlled by the computer, you need to start a backup power supply before the machines stop and the bunker will become your final gravestone.
