Dr. Conca opines that no one has ever died because of Swedish nuclear power. Nuclear power provides 40% of that countrys electricity, same as hydropower. Nuclear has avoided over 2 billion tons of CO2 emissions since 1980, same as hydro. Replacing nuclear with fossil fuel would kill an additional 50,000 people or so over the next 20 years and would triple carbon emissions.

Since 2011, Sweden has been a net exporter of low-carbon electricity to other parts of Europe. Sweden is farther along in its commercial nuclear waste disposal program than most countries (SKB TR-10-52), and is bu... More →

The staff at Planetary Resources say that when traditional mining companies evaluate a potential mining target, they have many general things in mind:

1. Is it technically feasible? 2. How much will it cost? 3. How much risk is involved, and 4. Will it yield a profitable return?

But the details get more challenging in choosing an asteroid target to explore for possible mining in space. The goals are the same, but the variables can be much different, and more difficult to assess.

An ore is any material that can be recovered from a mining or drilling site and sol... More →

After the baking heat of a Virginia summer, the spent fuel pool at Surry Nuclear Power station, which sits on the James river in the south-east of the state, looks almost inviting. That would be unwise. Some 25 feet below the surface of the clear blue water, the tops of radioactive fuel assemblies glisten. Every 18 months or more, a new load of spent fuel - uranium pellets encased in zirconium - is removed from the power station two reactors and put into the pool, which absorbs the excess heat and some of the most dangerous (and short-lived) radiation. There it sits for five years, before bein... More →

Californians are continuing to pump groundwater in response to the historic drought in the state. Meanwhile, the California Department of Water Resources (DWR) released a new NASA report showing land in the San Joaquin Valley is sinking faster than ever before - nearly 2 inches per month in some locations.

Because of increased pumping, groundwater levels are reaching record lows- up to 100 feet lower than previous records, said DWR director Mark Cowin. As extensive groundwater pumping continues, the land is sinking more rapidly and this puts nearby infrastructure at greater risk of ... More →

Erban, et al., conclude that deep aquifers in South and Southeast Asia are increasingly exploited as presumed sources of pathogen- and arsenic-free water, although little is known of the processes that may compromise their long-term viability. They investigated a large area (>1,000 km2) of the Mekong Delta, Vietnam, in which arsenic is found pervasively in deep, Pliocene - Miocene-age aquifers, where nearly 900 wells at depths of 200 to 500 meters are contaminated. There, intensive groundwater extraction is causing land subsidence of up to 3 cm/y as measured using satellite-based radar imag... More →

Tran Thi Viet Nga writes in Groundwater Management in Asian Cities, Volume 2 of the series cSUR-UT Series - Library for Sustainable Urban Regeneration, pp. 273-299 that in the last decade, arsenic-related health problems have been revealed as a serious problem in terms of the number of people at risk and the degree of the adverse health effects.

Since then, a large number of research studies and pilot projects have been implemented to find a solution to the arsenic problem. Some of them have been partially successful, but until now, there seems to be no ultimate solution that can b... More →

Bill Bainbridge reports that the research results, published in the journal Nature, show that a clean aquifer can become contaminated when water suppliers pump groundwater that contains naturally high levels of the deadly poison, arsenic. And while the decade-long study concentrated on Van Phuc, a small village on the outskirts of Hanoi, it has implications for the entire region.

Study co-auther Pham Hung Viet of the Hanoi University of Science says arsenic contamination is elevated because people are using arsenic-laden water for their daily cooking and drinking needs. The phenomen... More →

Suresh Bansal asks the question - Is the oil we rely on for energy really derived from organic sources (as per fossil fuel theory), or is it constantly being regenerated within the mantle from rocks (as per abiogenic oil theory)?

Scientists have sufficient evidence showing that commercially interesting hydrocarbons have been expelled from organic rich source rock and are trapped in the reservoir rocks. We also have compelling evidence demonstrating the presence of biological molecules in commercial oils.

But in addition to the evidence of an organic origin to oil and natu... More →

Loren Thompson opines that on August 15, only days before global equity markets suffered their worst declines in years, European plane-maker Airbus disclosed the biggest order in its history. IndiGo, a fast-growing economy carrier based in India, ordered 250 A320neo, the latest version of an aircraft that competes directly with Boeing 737. The eye-popping price-tag for the transaction was $26.6 billion, meaning that thousands of jobs will be created at Airbus sites in Europe. And not at Boeing sites in America.

Jeanmarie Ryan reports that muons are elementary particles that are 200 times heavier than electrons. A muon decays to form either an electron or a positron. Muons are created when cosmic rays interact with earth atmosphere, and they inherit the high energy of these cosmic rays. Because of this, they can pass through dense objects, although they slow down while doing so.

In the 1960s, Luis Alvarez came up with the idea of using muon tomography in archeology to study pyramids and ancient ruins. A muon detector is placed within or beneath the pyramid. It measures the energies and traj... More →

Muon tomography is a spinoff from particle physics by studying the magma chambers of active volcanoes. But it is also a new tool for geophysical mineral exploration. Other possible applications:

Monitoring carbon sequestration
Monitoring water seepage
Identifying voids
Archeology investigations
Monitoring nuclear waste and reactors
Scanning for contraband nuclear materials

A successful field trial has been performed. Muon geotomography imaged a known massive sulfide deposit in a complex geological environment. Inverted 3D density images of the dep... More →

Samir Patel reports that the prototype muon detector can identify stacks of bricks through concrete roof of a laboratory. A plot of the data shows that fewer muons make it through the densest material. Similarly, buildings around the detector cast muon shadows. A narrow green band corresponds to a corridor within the building. A similar signal might indicate a tomb in a Maya pyramid.
