This is a great device to promote given the current need for products that save both money and energy. It seems that this design can redefine what it means to recycle batteries. Considering most households are unaware of how to recycle batteries and their potential harm, this lamp will be beneficial for the education of people and the longevity of the environment. My concerns arise when I think about who will purchase these lamps. Chances are likely that if an individual is conscious enough to buy this environmentally friendly product, they already know how to properly disposal of harmful materials. On the other hand, if these were to be installed in public areas by the cities, do you think that citizens would actually bring their old batteries to these fixtures? I would argue that the latter is the best option because the product only drains the batteries, but does not recycle them. In this case, the city’s sanitation bureau could be in charge of collecting the battery shells after they have been drained and discard them. Still, the product only ”indirectly” promotes the healthy liquidation of these entities. Like you mention, ”If proper care is not taken in disposing the batteries used by the lamp, it would still have the same dreadful effects on the environment.” Another drawback to this design is that it does not seem to indicate when each battery is fully depleted. It only takes about 2 volts for the bulb to light, but if the combined total of the energy supply is less than this, every battery will probably be trashed considering it will become a tedious and untimely task to determine which battery still has juice left. Despite the flaws of this prototype, I believe that this product will have a huge impact on sustainability in real estate. It can potentially spare land from being exposed to the content’s harmful effects and provide a new source of power for artificial lighting. I look forward to hearing your thoughts on its impact in this realm.
