I named the device Jul’s Ark. After the July Revolution, it was called Ark for the people of August’s flood (Ark: A device or a container that helps humans and land animals surviving the Flood).
I did the design and some work, but Subrata, Mishkat, Hafsa, Rupak, Safa, Mahfuza, Suchana helped with the physical making as shown. They all came from the July Revolution. My technical team has been working in remote areas for a long time. It was difficult to complete this work without the help of the July revolution fighters. So, with respect to the July Revolution, the name of the August flood arc is Jul’s Ark.
It can be used to operate all electronic gadgets from mobiles to LED televisions. There is a system for turning on lights, there is a system for listening to music. There is a system for improving the network in weak mobile networks and enjoying 4G. Load capacity 250 watts, energy capacity about 300 watt-hours, lithium battery backup, weight 17.4 kg. Can be carried in hand like a radio. Battery life 5 years, panel life 15 years, inverter, charge controller no guarantee. However, if there is no accident, it will last 10 years. Very heavy electrical load cannot be given.

Trial of solar mobile charging station. Very simple. Hafsa has done all the work. This is for the flood-affected areas. Because if the grid is available there now, various places will be electrified and people will die. I want the charging station to be good and safe. About 50 people can charge their mobile phones/smart phones daily from a solar charging station.
