The way I see it, we haven't worked had on energy storage capabilities. We optimized for cellphones and Laptops, and these cover most of your day or more now. For homes, the market is still no that big, because batteries are expensive and electricity is widely available. As we move to solar, electricity will become very cheap in the day and very expensive at night. This will create the required capital to create storage solutions in houses and factories. Also you don't need a portable battery when installing it at home, so I think the cost could be reasonable.
