Towards a new electrical-energy paradigm

    I have always found it absurd that computer manufacturers borrow certain innovations and not others from award-winning designs, probably due in part to existing commercial interests.  Every laptop has a useful battery which allows it to retain energy when not connected to a wall socket, necessary in light of its portability and (hence) likely use outside of the normal confines of computer use. However, why this simple innovation has not been adopted in regular desktop computers is puzzling to me, as it would be an important factor in resolving common issues brought about by sudden electricity shortages. (Electric outages tend to ruin information on hard drives, which lead to ever increasing rate of errors.)

    Yet, the same could be said more broadly for the existing paradigm of electricity usage.  

    One of the leading obstacles to the adoption of solar power is the fact that, since solar power is not readily available on a 24 hour period, batteries tend to be needed for such systems. As is well known, batteries tend to be the weak link in these systems as these tend to degrade over time, and hence need to be replaceable on a regular basis.  Ultimately this need to replace batteries on a 'regular' bases undermines the economic models of solar-power electricity generation, degrading the inherent stability of such a system over the long run.  The sola cells might last a very long time, but the battery cells which constitute a secondary system do not.

    Notice, however, that the existing model presumes that batteries be a direct part of the electric household solar grid; the large volume means that their replacement itself becomes a significant overall investment.    

    However, consider the following alteration to the design layout.  Not everything in a household, strictly speaking, requires electricity for its functional basis.  One might postulate that if batteries were evenly spread throughout a household, instead of focused on a particular spot, this would create a new technological-economic dynamic.  What if every electric appliance had its own battery, enough to last it through a 24 hour cycle?

    If every appliance had its own set of batteries, presumably replaceable, this would possibly have a number of positive beneficial effects.  During peak energy when the sun is producing at its maximum output, but when electricity is likely not being used because most members of the household are outside of it, the appliances could be gathering residual electrical energy during nighttime hours.  A second benefit is that it would separate the functions of generation of electricity and storage of electricity, thereby creating a secondary vibrant market that would inevitably stimulate competition and technological innovation.   Each appliance in the marketplace would have an incentive to innovate relative to other rivals, to make it last longer and/or lighter. In the long run, this competition would benefit the overall quality of all batteries.  Finally, since each appliance would have its own battery, one would have to worry about replacing the battery of a particular appliance, rather than a large powerful system for the entire household, introducing safety factors into the list of benefits.

    The history of technology demonstrates that often it is not the technology per se but rather the surrounding social structure which hinders its broader adoption by a community.
