Three ways portable air conditioners reduce energy usage

Summary: There is a lot of room for savings when using a portable a/c, with better temperature control and more efficient cooling. One of the biggest costs for the average home is the energy bill. Cooling in the summer months is a costly affair and bringing it down by even a little will make a big difference over the long term. Here are three reasons why you can reduce your cooling costs by using a portable a/c: Energy efficient cooling The most obvious reason a portable air conditioner reduces your cooling costs is the mobility of the device. You...

Breathalyzer developed that detects lung cancer

Israeli scientists have devised a portable breath tester that detects lung cancer with an accuracy rate of 86%. Reported in the journal ‘Nature Nanotechnology’, the device could even act as an early warning system to flag disease before tumours are visible in x-rays. Using gold nano particles, the sensor detects levels of volatile organic compounds (VOC) measured in a few parts per billion. This increases in cancer patients. With lung cancer, early detection increases the odds of survival, though only 15% of cases are discovered before it begins to spread. Chest x-rays and CT scans can be used to detect cancer and reduce the lung cancer mortality rate, however, it is expensive and also exposes patients to harmful radiation. The study, lead by Hossam Haick of the Israel Institute of technology sampled breath from 56 healthy people and 40 lung cancer patients. The findings included that 33 compounds that appeared in at least 83% of the cancer group, but in lesser than 83% of the control group. Once the arrays were ‘trained’ to detect a selection of cancer-specific VOCs, it was tested on both artificial mixtures or biomarkers and real human breath. The researchers concluded that they were able to, “distinguish between the breath of lung cancer patients and healthy controls, without the need for de-humidification or pre-concentration of the lung cancer biomarkers.” The scientists also indicated that this...

Virtual reality on your mobile phone

Written by Costbuys The problem with the introduction of new technology has always been the initial cost. 3D took a long time to spread in Cinemas, and just as long when it came to consumer TVs. The same will be true for a lot of today’s emerging technologies like 4K, HDR etc. The worry is that as soon as they become affordable, they will be eclipsed by the next one, making it obsolete. Fortunately, it looks like Virtual Reality might not face the same fate. Let’s be clear, the primary virtual reality systems on the market, the Oculus Rift,...

Google self-driving car hits a bus

One of Google’s self driving test cars has hit a bus, in what is probably the first collision caused by the search giant’s test cars. To date all collisions so far have either been caused by other vehicles or by people driving the cars. The party to blame has still not been determined and Google will meet with the California DMV. In a statement, Google said: “We clearly bear some responsibility, because if our car hadn’t moved, there wouldn’t have been a collision. That said, our test driver believed the bus was going to slow or stop to allow us to merge into the traffic, and that there would be sufficient space to do that.” Google releases a report with details of its self driving car tests every month. The report read: “The Google AV [autonomous vehicle] test driver saw the bus approaching in the left side mirror but believed the bus would stop or slow to allow the Google AV to continue,” the report read. “Approximately three seconds later, as the Google AV was re-entering the centre of the lane it made contact with the side of the bus. “The Google AV was operating in autonomous mode and travelling at less than two mph, and the bus was travelling at about 15mph at the time of contact.” Google has also refined its algorithm after the incident: “From now...

Google paid Apple $1 Billion for its search bar

Apple received approximately a billion dollars from its rival in 2014 to maintain the search bar on the iPhone.The Oracle attorney who disclosed details of the Google-Apple agreement at last week’s court hearing, said a Google employee questioned during pretrial information said that “at one point in time the revenue share was 34 percent.” It is unclear if the percentage is the Apple or Google’s cut of the earnings. The assumption is that the 34 percent is in fact Apples. Google attorney objected to the disclosure: “That percentage just stated, that should be sealed,” lawyer Robert Van Nest said,...
