@ Elizabeth M, smart phones over charging is something we all do almost on a daily basis. Most of us plug in our smart phones and sleep. As a result it keeps consuming the power and becomes significant when multiplied by the number of users who do that. Such gadget can be handy because we are not really much to blame considering the relatively poor battery performance of most smart phones and the fear that we might run out of battery the following day.
In today's energy hungry world, may be starving if left uncared for, energy conservation can't be overlooked. Energy saving gadgets in any form should be welcomed. We often ignore some such gadgets because of the fact that they save very little amount of energy. But if we account for the energy saved when such gadgets are adopted by sizable population, it can certainly make the difference.
If every little bit helps keep the home more efficiient, here's a simple idea that could save quite a lot of energy.
Own less products.
Un-necessary energy consuming products can be phased out - excessive decorative lighting, unused kitchen appliances, digital gimmicks, TVs in every room - simply lose them, and lose their power consumption at the same time
Yes, a light-switch sensor is a great idea, too, Debera, I agree. No matter how much I try to be vigiliant about this even I still forget to shut off lights sometimes. Every little bit helps to keep the home more energy efficient.
Thanks for such an informative post, I really liked the idea of smart phone chargers and light switches because most of the time whenever we leave the room we just forget to switch the lights off and it utilizes a lot of energy specially children of today have this habbit at its most by using this sensor it will definitely help to save a lot consumption of energy .
I'm not sure the figures for the wireless charger add up. since wireless chaging is extremely inefficient compared to a simple plug and socket.
A conventional charger with 4 outputs would make more economic sense - then you can charge 4 phones while only leaving one PSU standby circuit in plugged in when not in use. (and you don't need multiple outlets).
Very interesting and informative slide-show Bradley. We had a power outage this winter due ice-laden limbs dropping across power lines. The Electric Power Board truck pulled up to the transformer behind our house to make the necessary repairs. When the gentlemen were finished, I took them a cup of coffee and started a conversation. As it turns out, that little transformer on the pole behind our house was running about 250 % of its rated same transformer has supplied five (5) houses for that length of time. The difference, I was told, is added demand due to computers, charging electrical devices; i.e. I-pads, I-pods, cell phones, paper shredders, etc etc. It's amazing how much power these devices use and even though incremental, it can be big when looking at one year's usage. Your devices, although small, can add up to $100s saved each year. Great post.
Bradley, this is an interesting cross section of devices. I really like the light switch and think that would be a very useful device. The nest device is good, but I think a lot of that functionality could be an app on a PC or smart phone with some sensors in the home.
The PC eco button is perhaps not so useful. If you have a large power hungry PC you are probably gaming and don't care. Otherwise, new PCs and laptops for general use are a lot less power hungry than devices in the past. They also have power saving features. A simple app could tell you all you would get from this device. There are probably such apps now.
Amazing slideshow Bradley. I never thought about the amount of energy we could save just by switching to an eco-friendly kettle. It's mesmerizing to envision how such little things can add up to save a lot of energy at a larger scale depending on the number of users. And then there are energy harvesting devices as well, thus we could certainly save a lot of energy plus money, by these small little adjustments in our daily lives.
Interesting slideshow, and I especially like the Belkin solution for charging your smartphone. I never think about how much energy I might be wasting by keeping mine plugged into the wall all the time. When people think about the smart home sometimes I think energy-saving devices and gadgets are overlooked, and these are good suggestions to bring energy efficiency to every-day functions in the home.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
