  • It boils down to chemistry. The nickle-metal-hydride chemistry used in rechargeable batteries just don’t produce 1.5V (explaining why is a lot more complicated), while the alkaline chemistry in non-rechargable batteries produces slightly more volts.In the same vein, lithium-ion batteries produce around 3.6V, while lead-acid produce about 12.4V.

    To answer your other question, they should be able to power most things that aren’t an analog clock (which might run slightly slow).













  • Basically, the anonymous peer reviewers told the authors “you should cite these additional papers in your work”. It’s expected that any such recommendations would be relevant to the topic at hand, and therefore are worth bringing attention to, but the authors clearly do not agree that they have anything to do with their research.



  • Because you don’t have a driveway/hose, I would try something like the Simple Green “OxySolve” cleaning concentrate (it says it’s for power washers but there are mixing instructions for “manual cleaning”). Most concrete cleaners have some pretty harsh chemicals in them that could damage your bathtub, but the Simple Green stuff seems pretty tame.
