    we’ll all get super ripped legs from hours on our exercise bikes retrofitted to generate electricity so we can charge our phones long enough to keep using them through the evening

    Biking for an hour only runs a lightbulb for a few seconds. Human manual labor will never generate significant electricity.

        Doesn’t that statistic assume a 60W incandescent?

        yea, but the best LED bulbs are something like 4x more efficient.

        So biking for an hour runs a LED lightbulb for 10 minutes maybe? I don't remember the exact figures but it's ridiculously impractical

        a fully distributed generation system comprising manual labor, geothermal, hydro, and some form of energy storage

        it's also impossible to make a system that takes advantage of the type of post-collapse labor you'd be doing. People won't be riding exercise bikes when you're trying to survive off potatoes and milk
