Comments Off on New rooftop cooling tech beams excess heat into outer space

Heat rises, and, with a little help from scientists, can soar as high as outer space. A team at Stanford University has created a roof-mounted system which cools buildings, without the need for electricity, by incorporating solar panel-like machines that beam heat into the cold expanse of space. This system, known as radiative sky cooling, is seen as an early step to developing a full strength system to cool buildings without the need for an external energy source. This could prove enormously beneficial in dealing with the impacts of climate change (a warmer planet) while reducing its causes (lowering emissions). Shanhui Fan, professor of electrical engineering at Stanford, and his team have been working on radiative sky cooling since 2013. Their recent research has demonstrated that the radiative sky cooling system is capable of lowering the temperature of flowing water to below that of the air around it. While Fan and his team have specifically harnessed radiative sky cooling for air conditioning purposes, this process is something that occurs naturally. “If you have something that is very cold – like space – and you can dissipate heat into it, then you can do cooling without any electricity or work. The heat just flows,” explained Fan. “For this reason, the amount of heat flow off the Earth that goes to the universe is enormous.” Related: Massive new data center to be built in chilly Norway to offset energy use The primary obstacle to achieving a net-temperature decrease through radiative sky cooling is the heat received from the sunlight. To solve this problem, the radiative sky cooling system at Stanford incorporates panels that are coated with a multilayer optical film, which has the ability to reflect up to 97 percent of the incoming sunlight . Using data gathered from small-scale testing, the Stanford team projected that a full-scale radiative sky cooling system would result in an 18 to 50 percent reduction in the amount of energy needed to cool a building. To further develop the concept, the team has started a company called SkyCool Systems and plans to incorporate their system into refrigeration and air conditioning models, with a particular focus on cooling massive data centers .

Stanford students take on dangerous superbugs

Comments Off on Stanford students take on dangerous superbugs

Antibiotic-resistant bacteria, or “ superbugs ,” are one of the biggest challenges of the medical community. They are popping up at faster rates as antibiotic use increases, causing serious alarm among professionals familiar with their power. A few undergraduate students from Stanford University believe they may be on to a revolutionary idea that could kill off some of the most dangerous superbugs out there. Last fall, students Zach Rosenthal, Christian Choe and Maria Filsinger Interrante entered a Stanford University competition to provide solutions for major healthcare problems. Their idea of developing a set of proteins to annihilate antibiotic-resistant bacteria won them a $10,000 grant to test their hypotheses. “As soon as I started to read literature about multidrug-resistant bacteria, I decided it was a huge need area and interestingly neglected by the pharmaceutical industry,” said now-graduated Filsinger Interrante. She says that a smaller market size, lower profitability, and seeming inevitability of drug resistance lowers manufacturers’ enthusiasm about producing new antibiotics . Related: Dangerous antibiotic-resistant bacteria found in food products for the first time The specifics of their project are being kept secret, yet Rosenthal explains the mechanism of their attack, “We target something that’s essential to bacterial survival.” Preliminary reports of their tests are successful and the team hopes to continue working toward finding the Achilles heel for Pseudomonas aeruginosa and Acinetobacter baumannii , two of the most drug-resistant and fatal superbugs existing today.

Comments Off on Ancient crystals may hold a “signature of life” 300 million years older than previously thought

Each time scientists announce a new discovery on the origins of life, they have to do so with a grain of salt because a future finding may expand on what we think we know about our planet’s early history. This time, it’s the age of ancient crystals found near Perth, Australia, that have researchers questioning earlier held assessments of the beginnings of life on Earth.

Comments Off on Brilliant Stanford invention makes hydrogen fuel-cell powered cars even greener

In the next few years hydrogen fuel-cell powered cars are going to become more readily available thanks to new models from Toyota, Honda and Hyundai. While automakers have labeled the fuel-cell vehicles as the ultimate green vehicle, since they only emit water, there’s a dirty secret that isn’t talked about. The process to produce hydrogen isn’t very green, but a new invention from Stanford University could change that.

Comments Off on VIDEO: Stanford Team Successfully Tests Earthquake-Resistant House

A team of Stanford engineers have built and tested an earthquake-resistant house that sits on top of sliding “isolators” to ride out tremors. The test house, which also makes use of heavy-duty reinforcing, withstood an earthquake simulation that was three times the intensity of the Bay Area’s devastating 1989 Loma Prieta quake. The team says the modifications are inexpensive and could easily be used in new home construction where their costs would soon be offset by reduced earthquake insurance premiums.

Click here to view the embedded video. David Letterman took a break from chatting up celebrities and movie stars to talk about something serious and imperative for our country – renewable energy . Mark Jacobson , Professor of Civil and Environmental Engineering and Director of the Atmosphere/Energy Program at Stanford University chatted with Letterman earlier this week about how the US can transition to using 100% renewable energy. The fact that this urgent topic got serious air time on a major network during a late night talk show is amazing enough, but the fact that Jacobson has a plan to help is even better.
