Only if there are no subsidies on the energy. None at all. No subsidies on the building of a power plant. No subsidies on the mining of coal. Nothing. Nada. In fact, throw in a 100% tax because of the pollution caused by the generating the energy. Then decent bulbs will have a fair chance over the outdated ones and the US financial problems will be solved quite quickly.
In many shops and similar places we have drums like this battery drum. In one week I see at least 2 different ones. One on my daily commute in the bike garage under the train station and one on my weekly shopping in the supermarket. That is how we make battery recycling easy. I don't have to think about it every day. When a non-rechargeable is empty I can put it in my pocket. When I see the drum I often remember the battery in my pocket and I can throw it in there.
He may be using a 500 W floodlight. They are approx 3600 lumen. I would go blind trying to read anything in such a light, but maybe welding goggles are a fashion statement for him. A 50W LED floodlight gives 3500 lumen, has a similar shape to a halogen light and costs about EUR100 ($136.35). A halogen floodlight costs about E20 here so the difference is E80.
For those who don't know how to calculate the savings, her is how the calculation looks for me: I use an energy price of E0.2171 p kwh (Electrabel in The Netherlands charges that. It isn't a strange price in The Netherlands, with taxes upon an already high price and all that. It is the price I could find.), Your electricity may be cheaper.
Once we save 80/0.2171=368.5 KWh the LED is cheaper.
The power usage difference is 0.45 KW, so each hour it is on the LED light will use 0.45 KWh less than the halogen light.
This means the LED light will be cheaper after 368.5/0.45 = 819 hours.
Unless your house has a really, really bad power supply the LED will survive this a few times over. Most don't reach the claimed 10,000 hours but most will reach 5000 hours. The savings are gigantic (your energy cost may vary).
By the way: those who claim that the US government shouldn't forbid incandescents should see that not interfering also means all the energy subsidies should be removed and the cost for removing the CO2 and other crap from the atmosphere should be added to the price of electricity. Perhaps by means of a tax. The price of a KWh would probably be more than a dollar.
That can be solved with an inverse sloped glass, combined with a slight modification that removes any snow catchers. You can even include a heating element to melt the snow and ice. You still save loads of energy because that heating element is off 80% of the year (depending on local conditions).
Point is that when you apply new technology not everything will work first time around.
Nope. The current scales linearly with the voltage, but that doesn't mean they are linear. As a incandescent lightbulb is dimmed the filament temperature drops. A lower filament temperature means it sends more energy out in the infrared spectrum. The result is more like this graph. Not linear.
Nope, it's a trade off between efficiency, color and lifetime. It is possible to make an incandescent bulb last 100 times as long as they do now. Just lower the temperature (by means of a lower supply voltage or a higher internal resistance). Of course, lowering the voltage means that the light will be more reddish and it will mean that a bigger fraction of the energy will be in the infrared spectrum where it is wasted.
I wouldn't use the name money for that. It's to confusing as there is already a system with completely different features under that name. You should call it credits or something like that.
Nope, my head doesn't get too warm in it. I have averages of 30 km/h and regular peaks of 48 km/h. I do, however, use a non standard bike: a quest. This helps me keeping speed with ease.
This is already for sale
as the Abus Kranium It is a rather expensive helmet, as it costs about E100 while a normal EPS helmet costs E50. However it is also a lot better, so when you bike a bit faster than 24 km/h (15 mph) it is still useful. Over time the helmets will get cheaper if everyone buys them (economies of scale) and they are proven better.
Well, an additional H results in H3O. The ionized version of that (H3O+) is quite common and a native element in plain water. Even distilled water, because it forms with OH- from 2 H2O molecules.
However, an additional oxygen molecule does give H2O2. You point stands.
That is until they get ripped apart by the dark energy forces of our ever faster expanding universe. After that the free neutron decay will allow the neutrons to decay into electrons, protons and antineutrinos. All of these have known decay paths which all end in radiation if I am correct. That radiation will redshift into nothingness by the expansion of the universe in infinite time (because that is what it takes to redshift into nothingness). That is, if my current understanding of these things is correct.
Finally package delivery through a pneumatic tube system takes off! And we have years to perfect it before the year 3000 when everyone will be to lazy to walk across town and just take the tube.
Not all artificial legs need control over the movements. If the prosthetic leg starts below the knee there is little need for an active joint. Keeping balance while standing still will require training though. If the hip joint is intact the user can throw the foot forward to get the leg where he wants it. Then the user can stand on it and the pressure on the leg can lock the knee. It isn't easy to walk this way but it can be done and beats having nothing or something that doesn't fit, which is often the case in third world countries. Oscar Pistorius can run far faster than I can and he has no electric control in his prosthetic legs. Granted, he only has lower leg prosthetics and a lot of experience with them, but it seems to me that walking with unpowered prosthetics is possible.
The best thing about a phone controlled combo microwave would be that the idiotic controls can be replaced with useful ones. I don't need a "defrost by weight" that chars parts of the meal and leaves other parts frosted. I don't need a "heat a cup" setting that doesn't compensate for cup volume or required temperature. I don't need a crummy oven + microwave setting that doesn't allow me to change the microwave power. What if I need to heat up the core a little but want the exterior to be heated with the oven? 600 w of microwave power for 10 minutes is a lot of power and 10 minutes of oven baking at 180 C is not much I simply need 4 dials. 1 for the time, 1 for the microwave power, 1 for the oven temperature and 1 for the grill temperature. Mix and match as required. However there are no combo microwaves that give me that.
This may be true, but it would also result in a greater risk of hypothermia. If the extremities are better heated by blood that means the heat is lost quicker. If the dog doesn't have the calluses and skin to protect the paws from this heat loss a long walk in extreme snow will probably kill them. Warning: I am not a vet. I am merely using logic and the posts I read on the internet. A vet will be able to tell you if putting shoes on your dog is a good idea. I do not know if your dog likes shoes on it's paws.
You don't need gravity. The analogy works perfectly with a hook or which pulls the dent in the sheet instead of the ball and marbles that magically stick to the sheet instead of being pulled towards the sheet by gravity. No problem, but you'd have to do it in zero gravity. We just use gravity because it is easy to do so. We have plenty of it and people understand it. An analogy is a way of explaining a difficult concept with the concepts people do understand. If we make it too complex the concept will not land for many people. The ball and sheet is a simple analogy for a difficult concept. Not perfect, but good enough for most people.
No. Small columns on a big screen is just wrong. It results in a difficult to read, difficult to understand mess without any decent reason to do so. On a big screen the content should usually be a single column at least +/-80% of the with of the screen width, with a bit of space for a menu bar (if you want it there.). Only if you have a very good reason you can do that in an other way. On a small screen there is no good reason to have the menu on the screen all the time. Just let it scroll away at the top where everybody expects it to be. Browsers are well capable of reflowing text. Let them.
This means that the location of the menu bar is the only difference between a small screen and a big screen, easily detected with some javascript (be it screen width or user agent string).
A smart glass should order a new drink if the time the waiter needs to bring a refill approaches the time estimated to enjoy the rest of your current drink A smart glass would advise you on the next special beer or whiskey, based on your current and previous drinks. A smart glass would stop dispensing alcohol if it estimates the user is stupid enough to drive home and the alcohol consumption has exceeded the legal limit. It would, however still be usable for 0.0's and malts. When it is full it is not advisable to place a smart glass on your head.
Imagine, if you will, a three by seven inch wooden frame -- a frame that's a gateway to a world of imagination. Wipe your mind on the welcome mat. You're about to enter The Scary Door.
