The coastal waters of Massachusetts, USA encompass tidal phenomena that generate flows of sufficient magnitude for commercially viable power extraction.
It has some phosphate resources which, as of 2011, are not economically viable for extraction.
To determine the likelihood of cell transfer from mother to pup via the milk under normal conditions of nursing, we first determined whether the GFP+ milk cells were viable after extraction from the stomach of the pups.
The real driving force behind the shale boom was not the investments in capacity, but the investments in technologies that made extraction viable and economically feasible.
Firms that had used unrealistically low cost estimates for extracting oil from ageing fields have suddenly been bailed out of trouble by the price rise, which makes extraction viable, and thus reserves proved, even at a higher cost.
Cuadrilla has taken over the site in the hope that modern technology − including refined drilling processes, the possibility of drilling horizontal wells branching off the main vertical well, and if these techniques fail, the use of fracking − will make the site economically viable for oil extraction.
Thermochemical pathways for conversion of microalgae and fungi to biofuels present a viable alternative to extraction technology.
On one level, the proposed approach reflects a pragmatic response to power relations and dynamics within society as it is often not politically or socially viable to control extraction and, as a result, adaptation is essential.
Grassroots groups, such as the Madang-based Bismarck Ramu Group, aim to protect local communities and inform them of viable alternatives to resource extraction – such as agriculture.
Over the past decade, technological developments and soaring oil prices have made its extraction economically viable, making it a prime destination for major international oil companies.
