On a great, sunny day, you decide to use your tablet or mobile phone outdoors for some time alone. But unfortunately, the battery of your device has been exhausted in just one hour. Directly go home to charge? This may not be necessary. If the Soofa solar bench becomes a public utility, it will provide all this. This sounds simple and practical enough. Soofa's solar benches take full advantage of the sun's energy and store the voltages that are in demand, just in time for the next person, without consuming everything, to charge the next mobile device that fits him or her. Soofa is the brainchild of changing the environment and was launched by the MIT Media Lab. Currently, the only benches being installed are in Boston and Cambridge, Massachusetts. Just no data has yet been sent to the site, but once everything is set up, the site will display data such as the number of charging devices, who has made the visit, and how much electricity is available during the day. 
You may be wondering what the overall purpose of Soofa is. Promote social development because it is one of the social technologies. Co-founder Youta Friedrichs said that the computer has been imprisoned in the user's house and can only be connected through the Internet. Now is the time to get them back in the sun and interact with flesh and blood. If there are any indications, what better way to get out of the house is to provide free charging.
