To save money, emissions and indulge my inner geek, I’ve tested the Google Powermeter – and it has not been an entirely pleasant experience. | |
Not content with dominating the way we send email, find information and navigate the real world, Google now hopes to manage your home’s energy use. In the spirit of saving some money, emissions and indulging my inner geek, I signed up to see whether its Powermeter really is the future. For the past two months, the software—which arrived in the UK in November—has been tracking and broadcasting to a web page how much electricity my early-20th-century, three-bedroom terraced house consumes. It’s not been an entirely pleasant experience. While I had it setup in 10 minutes —using a small hub and sensor from British company AlertMe to plug into my web connection—seeing my electricity use on an iGoogle page alongside my email, news, RSS and other widgets was sometimes a scary reminder of our profligacy. Our house typically rests at around 150 watts running a computer, fridge and a couple of lights, but it’s not uncommon for that to jump up to more like 3kW (3,000 watts) with the washing machine and dishwasher running simultaneously. In December as a whole, the Powermeter graph reminded my daily, we used a shockingly high 370 kWh – but fortunately December’s also probably our highest month for energy use, because it’s one of the darkest and the one where we’re most frequently at home. Google Powermeter makes looking at your energy consumption almost fun – at least in comparison with deciphering cryptic energy bills. While you can download the raw data of your electricity use, a quick look at the baffling spreadsheet showed the importance of a meaningful interface such as Powermeter’s graphs. Interestingly, while I was trialling the service, Google dropped Powermeter’s comparison feature —where you can see how your use compares with US regional averages—because it felt homes varied between regions to the point of making comparisons meaningless. I’m inclined to agree. Usage for our three-bedroom terrace house was regularly described as very good and akin to a one-bedroom apartment, which doesn’t tell me much, except how high US domestic energy use is. I’ve also been trying British Gas’s new EnergySmart tariff, which gives you an energy monitor gadget and makes you submit monthly meter readings. Charles Arthur has reviewed a version of the monitor—he was impressed—but the most useful part of the tariff for me has been the financial incentive to save money on a month-by-month basis, knowing that each kWh saved will be reflected on that month's bank statement. Ultimately, the really interesting stuff for this technology will come when all this data gets shared socially – and results in the sharing of advice and the application of peer pressure to make people change their habits. While iGoogle and Powermeter doesn’t let you publish your energy use direct to Twitter or Facebook, AlertMe offers a personal “Swingometer” to post a basic image of your energy use on Facebook, Twitter or your blog. Meantime, the best way for most people to try an energy monitor—without spending £69 plus an ongoing £3 monthly subscription for AlertMe and Powermeter—will be to borrow one from their local library. A trial that started in Lewisham has since spread across the country, from libraries in Leicester and Brentwood to Cardiff and York. Not for the first time, old-fashioned institutions of learning could trump new-fangled technology and gadgets. |
In another three years, the world will see the Universe’s splendour and its inherent majestic patterns from a completely new window when the Planck microwave observatory comes out with its results. “It will be a complete surprise. I dare not to even imagine,” Nobel laureate physicist James C Mather who first saw those grand designs two decades back, told Deccan Herald on the sidelines of the 97th Indian Science Congress here. Mather was one of the scientists who first analysed the data collected by the Cosmic Background Explorer (COBE) — the famous 1989 NASA satellite that provided clinching evidence in support of the Big Bang. The Universe is believed to have been originated from an enormous explosion, Big Bang, almost 13.7 billion years ago. The COBE results not only proved the all-pervasive presence of the cosmic microwave background (CMB) — the relics of the Big Bang — but gave the first clue on how the universe looked like in its early days. “When we presented the results in a scientific conference in the USA, we received a standing ovation,” recounted Mather, who received the Nobel Prize for the discovery in 2006. The research on understanding the universe in its early days, however, did not stop with the COBE. Second probe In 2001, NASA launched a second probe called WMAP — Wilkinson Microwave Anisotropic Probe — to look into the baby universe up and close. It is the WMAP that helped scientists fix the universe’s age at 13.7 billion years besides providing hints towards galaxy formation. But questions still linger on how the universe cooled so rapidly within such a relatively short time creating small galaxies, which later combined to form the larger clusters. Stars like the Sun and planets such as the Earth were born from those galaxies. But scientists do not have much clue on the nitty-gritty of the formation. That is why the European Space Agency launched Planck observatory in May, 2009, to measure the CMBR with much more sensitivity. The detectors, on board, the Planck observatory are looking for variations in the temperature of the CMB that are about a million times smaller than one degree — a feat comparable to measuring from Earth the body heat of a rabbit sitting on the moon. The first light survey for the Planck observatory was completed in August, 2009, giving astronomers high hopes because of its excellent data quality. Within its operational life of 15 months, Planck will be able to gatherdata for two full, independent all-sky maps, which will be studied with great detail for two years. The results from the Planck are expected towards the end of 2012. |
Imagine owning a car that does all the driving while you sit back and relax. Your fantasy seems to be getting closer to reality, thanks to scientists who are designing such a ''self-drive'' vehicle. | |
A European team claims to be working on such a fantasy car which can drive itself -in fact, tests would start next year on such vehicles that “drive themselves” and could be on roads within 10 years, The Daily Telegraph reported. Co-ordinated by a UK company, the European Union project is called Safe Road Trains for the Environment and it involves a “carpooling” roadtrain theory for use. The roadtrain would consist of six to eight vehicles whose occupants would be able to relax, read the paper or chat on mobiles while travelling; this’ll be possible as their cars would be equipped with a navigation system and a transmitter unit that communicates with the lead vehicle, say scientists. This lead vehicle—possibly a taxi a bus or a —will drive “normally” and effectively “do the motoring” for the rest of the roadtrain. Drivers approaching their destination will take over control of their own vehicle, leave the convoy by exiting off to the side and then continue on their own to their respective destinations. The other vehicles in the roadtrain close the gap and continue on their way until the convoy splits up. The road trains increase safety and reduce environmental impact, thanks to lower fuel consumption compared with the cars being driven individually, the scientists say. The reason is that the cars in the train are close to each other, exploiting the resultant lower air drag. The energy saving is expected to be in the region of 20 per cent. Road capacity will be able to be utilised efficiently. The Sartre project will be conducted for three years on test tracks in the UK, Spain and Sweden and eventually on public roads in Spain. |
