This got me thinking about what we could and could not do if we had a magical a energy-unbottlenecker, say an infinite capacity battery with arbitrary power output. These become much cheaper: - Transport: synthesise fuel from CO2 + seawater. Or charge a battery. - Water: electrolysis of seawater. - Food grown anywhere: Light + water + fertiliser can be made from commonly available materials. Soil is a bit trickier, but I think you could bootstrap up with composting. - Global warming: pull CO2 out of the air. - Raw materials (concrete, metals): all cheaper to extract with free energy. - producing medicine Still really hard: - making new treatments - inflation of housing prices - escaping earth's gravity (need bounce per ounce) - world peace - writing books - politics
