The research could lead to a generation of light detectors that could see below the surface of walls
and radio waves can t always penetrate such as inside walls or bridges and below ground where there might be at least small temperature fluctuations.
For instance the device could be placed in an attic or inside a wall and sensors would be tuned to check for water leaks.
Similarly when used inside a bridge the sensors could detect any cracks forming or structural deficiencies.
In both cases the sensors would send a signal to the nearby powered receiver. A temperature change of only 0. 25 degrees Celsius creates enough energy to power the sensor node to read

#For better concrete, do did as Romans University of California Berkeley rightoriginal Studyposted by Sarah Yang-Berkeley on June 5 2013uc BERKELEY (US)# Ancient Roman structures that have withstood the elements for more than 2000 years
The discovery could help improve the durability of modern concrete which within 50 years often shows signs of degradation particularly in ocean environments.
The manufacturing of Roman concrete also leaves a smaller carbon footprint than does its modern counterpart.
The process for creating Portland cement a key ingredient in modern concrete requires fossil fuels to burn calcium carbonate (limestone) and clays at about 1450 degrees Celsius (2642 degrees Fahrenheit.
The production of lime for Roman concrete is much cleaner requiring temperatures that are two-thirds of that required for making Portland cement.#
#Roman concrete has remained coherent and well-consolidated for 2000 years in aggressive maritime environments#says Marie Jackson a research engineer in civil and environmental engineering at University of California Berkeley.#
and colleagues characterized samples of Roman concrete taken from a breakwater in Pozzuoli Bay near Naples Italy.#
Of particular interest to researchers is how Roman#s underwater concrete endured the unforgiving saltwater environment.
The recipe for Roman concrete was described around 30 BC by Marcus Vitruvius Pollio an engineer for Octavian who became Emperor Augustus. The not-so-secret ingredient is volcanic ash
which Romans combined with lime to form mortar. They packed this mortar and rock chunks into wooden molds immersed in seawater.
Rather than battle the marine elements Romans harnessed saltwater and made it an integral part of the concrete.
Also key was a very rare hydrothermal mineral called aluminum tobermorite (Al-tobermorite) that formed in the concrete.#
#Our study provided the first experimental determination of the mechanical properties of the mineral#Jackson says.
Use of Roman concrete decreased because#as the Roman empire declined and shipping declined the need for the seawater concrete declined#Jackson says.#
#Earth-friendly alternativewhile Roman concrete is durable it#s unlikely to replace modern concrete because it is not ideal for construction where faster hardening is needed.
But the researchers are now finding ways to apply their discoveries about Roman concrete to the development of more earth-friendly and durable modern concrete.
#There is not enough fly ash in this world to replace half of the Portland cement being used#says Paulo Monteiro professor of civil and environmental engineering.#

These charging locations use Tesla Wall Connectors for charging. Tesla confirmed with The Motley Fool that there are about 350 locations in North america and more than 800 worldwide.
Most of these locations have two Wall Connectors, says Tesla spokeswoman Alexis Georgeson. Wall Connectors are popping up at hotels, casinos, ski resorts, restaurants, shopping centers, airports,
and even mobile phone stores. In the U s.,Wall Connectors are showing up at well-known names like Costco, Hyatt, Four Seasons, Ritz-Carlton, Best western, and Westin.
Tesla Destination Charging program has exploded out of nowhere with initial efforts in rolling out the program beginning early in second quarter 2014.
Wall Connectors give Tesla owners a charge rate of up to 58 miles per hour when paired with Dual Chargers,
Tesla owners without a second onboard charger can charge with a Wall Connector, too, but they shouldn expect to charge at a rate higher than 29 miles per hour.
or more long enough to get a meaningful charge from a Wall Connector. Like Tesla Supercharger network, these Wall Connectors are free for Tesla owners.
Compelling economics The economics for all parties involved are compelling. The cost of the Wall Connector is minimal;
the company sells the contraption on its website for $650. And the installation of a 240-volt circuit isn expensive probably no more than $3, 000 and as little as $500.
offering free Wall Connector charging is a low-cost way to provide greater customer convenience while also potentially serving as a marketing tool.
when not having Wall Connectors could become a slight disadvantage for hotels and restaurants. While Tesla investors shouldn count on such an optimistic scenario,
