...many times over. Of course, it helps that Tha Carter III is one of the best albums of the year. It's a pop play--and smelling it, everyone from Jay-Z to Robin Thicke jumped on board with contributions--but it's still weird enough to sound like underground Lil Wayne. His wordplay can be thrilling ("My picture should be in the dictionary next to the definition of definition"), and no other rapper finds as much joy in rhyming; "in the way," "everyday," "what we say," "cliché," "Andre 3K," "sensei" is a typical string from Dr. Carter, his prescription...
...carbon you collect? For starters, you could sell captured greenhouse gasses to, well, greenhouses; farmers pay up to $300 per ton for the stuff to help plants grow. If the scrubbers were deployed on a grand scale, though, lakes of liquid CO2 would need to be pumped into deep underground reservoirs. A more exciting--if more remote--possibility is to combine CO2 with hydrogen and convert it back into fuel that cars could burn again. This would release more CO2, which scrubbers would pull back out of the air, in a closed loop...
...Innamincka has some of the hottest rocks anywhere, and Geodynamics has spent $150 million drilling deep into them. The biggest and most advanced of some 40 companies seeking to capture Australia's underground heat, it aims to be the first to prove that deep-earth geothermal power is commercially viable. Geothermal is already a bit player in the power business: underground water heated by volcanoes is already used for heating and electricity generation in countries like Iceland and New Zealand. But supplies of natural hot water are limited. The new push is to mimic nature by creating artificial water-heating...
...original plan was to pump water deep underground under high pressure, in order to crack the granites and create a path for the water to flow. Superheated by contact with the rock, the water would be pumped to the surface from a second well 1 km away, to create steam to drive a power turbine, then be pumped into the earth again...
...surprise, says Grove-White, was that there was no need to add water: it was already there, trapped underground at high pressure for the past 3 million years. Getting the hot water to the surface hasn't been easy, and one well had to be abandoned. But Geodynamics now says the flow from 4 km deep is sufficiently strong and hot to run a 1-MW power station by the end of the year - enough to power the drilling-camp site and Innamincka...
