To allow comparisons over time and between locations, spirometry should be performed according to established guidelines and standards.24,25 For ...

Short range electric or compressed air powered vehicles, with range of a few tens of km, could then be used to ship capsules from the node to the surrounding area and vise versa. The pipes themselves would probably be polymer lined concrete. Pipe runs should be as straight as possible to ...
If any of the many guesses underlying these scenarios should prove correct then the scenarios might be accurate, that is part of the reason for including a range of scenarios. Prices, well costs, and transportation costs could all be lower or higher in the future than what I have chosen, ...
The gravitational force is long range but very weak. It is mediated by mass so gravitational storage infra-structure will be very heavy and very large – a la pumped hydro. The nuclear forces are very short range – sub-atomic distances. They are not at all amenable to direct technological...
