Mobility & Global Warming
Working in an industry that contributes to the problem, I’ve been thinking about this issue for a while. Our part of the problem comes from the demand we create -- specifically, all those batteries need chargers. And we’ve been pretty brute-force with our uses of these; how many cube transformers (a.k.a. wall warts) are merrily sucking Watts out of the planet when they don’t need to? It might very well be that little steps, like fixing this problem, can really add up here, and, while the impacts of global warming will undoubtedly be felt for centuries, the sooner we start on a solution, the better.
So, someone please invent a circuit that turns off the transformer when the battery is fully charged, and turns it back on when the battery self-discharges to, say, 50 percent. If every cube transformer connected to a rechargeable battery were required to do this, how much energy might be saved? I’ll bet it’s significant. And it is at the very least time for us to do something significant, as an industry, and as individuals.
