LUS Patent & Trademark Office has published an Apple patent application that reveals Cupertino's renewed interest in solar energy. It is not a novelty that Apple is interested in solar energy, so much so that in the past years several patents have been submitted and obtained in this sense. The one presented today, however, shows a significant step forward for Apple, given that it concerns the possibility of resorting to external solar panels to power iPhone, iPad and Macbook, without having to resort or expensive converters. In other words, this patent proposes a solution that can be implemented in the medium, or even short, term.
As we read in the patent literally entitled "Energy management system to accept solar energy adapters in electronic devices, Apple would not be trying to invent new solutions to exploit solar energy from scratch, but take advantage of existing technologies and combine them with components currently available on the market. The study towards this alternative power supply system became necessary, explains Apple, by virtue of the powerful hardware on the market today. Smartphones, iPhone primarily, uses increasingly advanced technological components, which require more and more power and which heavily affect battery life. Apple rightly notes that users are increasingly enslaved to a power outlet.
The solution to this problem could be just small solar panels. On closer inspection, there are already portable battery chargers on the market based on this system, but with various limits. And, in fact, given that the solar energy of these panels is supplied with very variable and fluctuating voltages and powers depending on the amount of sunlight received necessary, that there is always a battery inside these chargers. And the latter that is recharged by sunlight and which, in turn, recharges the device. The substantial novelty proposed by Apple would consist of overcoming these problems and delivering energy directly from the panel to the battery of the device. In fact, the patent presented describes a micro power controller integrated in the adapter, capable of directly channeling solar energy and continuously supplying it at the necessary voltage.
Apple's next step to powering its mobile devices through renewable sources may not be too far away. In this regard, we recall that Apple is a strong supporter of these sources of clean energy, given that 75% of its corporate structures are already powered by renewable sources today. Previously, the same house in Cupertino said it would soon reach 100%. That solar panels applied to iPhones and Macbooks represent the shortest way to achieve this goal?
