Question : Is wireless transmission of power over short distances feasible?
It seems that everything is going wireless these days by using radio and infrared communication. Bluetooth is being put into most portable electronics,everyone including kindergarteners carry cell phones, laptops are all wi-fi ready, wireless mice and keyboards are sitting untethered on people's desks, but we are all still plugged in to the wall. (I know laptops break free from time to time, but as they get older, they tend to get plugged in more often.)
Will we see wireless transmission of power to our appliances any time soon? I realize that this has been done over very short distances, like rechargeable toothbrushes and recharging pads for portable electronics, but I want to know for distances from 1-50 feet. Or would it be too dangerous to have such huge quantities of power floating through the air? If we used directed energy, would people get fried it they crossed the beam? What do you think?
Can anyone provide studies that suggest that this is not feasible? Also, please read the question, I am talking about transmitting power over a distance from 1-50 feet. More takers please! I only got one good answer so far!
Answer:
Yes. For distances of 50 feet or so, it is definitely possible to transmit power. A RADAR is a good example. Think of a microwave oven with a directional antenna. The more power you want to transmit, the more dangerous it is to a person that gets in the way of the beam. Not really "cancer" dangerous. More like "crispy fried" dangerous.
The problem is that it's very inefficient to transmit power in this way. When you transmit electricity via wire, you only "use" power if you turn on the appliance. When you "beam" energy, it is gone whether or not something is making use of the energy on the other end.
You might be able to have some sort of directional system that only turns on when needed, but then if you wanted to move the object that is receiving power, you'd need some sort of automated tracking system with the transmitter continually redirecting power to the moving appliance. And if you don't need to move the object receiving power, why not just hook up a cord and save yourself the extra expense?
Also, the process of converting regulated electricity into RF and back is enormously wasteful to say nothing of the power lost over the transmission distance. And like I said before, it's very dangerous to transmit large amounts of power this way.
You'd have to think of an application where "beaming" energy is better than our current "plug in and recharge" model (like your bluetooth headset / laptop computer for example). You'd want an application that needs very little power, and is fairly close to the power source.
One practical application I know of is RFID tags. They are little microchips that are powered by RF energy. They are used to store information that can be retrieved when the RF-transmitting "reader" asks for it.
I suppose solar powered calculators (and any other solar powered device for that matter) are technically another example. Power is "beamed" from the light source to your calculator.

Question : wats a good power toothbrush?
under 20
Answer:
Seriously, my dentist tried to sell me one that's like, $125, which I did not buy. I use the Crest Spin Brush. It's only $8 and the heads are replaceable. My teeth feel nice and clean. I also floss. It's nice and cheap.

Everytime my wife brushes her teeth with her electric (battery powered) toothbrush, the picture on the TV (which is downstairs) goes mad. How can this happen??
Answer:
we have the same problem when the boiler comes on, i know its a pain it drives me mad, and were told that some digital boxes are sensitive. Have you tried using it in a different room??? i know this is a pain but worth a try, we moved the TV and it made a difference good luck

Question : Do you think I'm entitled to a refund on a battery powered toothbrush I bought from Tesco?
I bought one and in order for it to function, I had to open the bottom of the toothbrush (to insert the batteries which were included) with a coin. I and my mum tried every which way we could to get the damn thing open and I nearly dislocated my thumb! I decided to take it back to Customer Service at Tesco and asked them for a refund. I got no reply and she disappeared out the back and I noticed she managed to get it open herself with a coin. I said,"Well, can you close it now and do it again, to make sure". However, whilst she was doing so, the head of the brush touched the dirty desk and phone and I said, "Well, I can't use it now, it’s touched everything”. She said, “But there’s nothing wrong with it”. So, I was left without a refund. What do you think?
Answer:
Stupidity runs rampant in the world today. It’s clear by the responses who the idiots were that gave you thumbs down, Jus Curiuos (who can’t spell), susie x, and Medium Dave. These idiots probably work in customer service too. The very term customer service is to ensure a satisfied customer and a repeat customer.

Question : Which is better a battery powered toothbrush or a rechargeable toothbrush?
I'm currently looking into battery powered and rechargeable toothbrushes but I'm not sure which is better and which one to go with. I am torn between the oralb vitality and the oral b advanced power 400 series and the oral b cross action power. All of which are battery powered except for the vitality. The vitality brush heads all except for the sonic vitality brushhead fits the oralb advanced power. So my question is which is better, battery powered or rechargeable?

Question : Hi guys, what is the best powered toothbrush that one can get in the market?
I mean there are tons out in the market, but what do you reckon is the best to get currently. Something that would not only clean, but also help to sort of floss, clean between the teeth, dislodge plaque without damaging the teeth, and prevent plaque build up.
My doctor cousin recommended ORAL B SONIC COMPLETE, But when I checked the oral b website they have a latest model called Oral-B® Triumph™ ProfessionalCare™ 9000. Now I am tempted to go with the Triump Professionalcare. Have any of you used any of these models? What do you recommend based on your experience.
I am obsessed when it comes to my teeth. In fact my first cavity was a result of over flossing! and not eating sweets. Please help someone who acts like MONK when it comes to his teeth!
Answer:
I know exactly what you mean! I'm the same way about brushing and flossing. The Sonicare by Phillips is the one I've found to be the best. It last for years with out having to replace it, holds a full charge for a week making it great for taking it on vacations without having to take the base. It does an excellent job at cleaning the teeth by using an ultrasonic vibration that works with toothpaste and your saliva gently removing all debris in between and below the gum line. After using it, you really do feel like you just had your teeth professionally cleaned. I should know since I've used and recommended them for the past ten years and I am in dentistry.

Question : Is there any different between Battery Power Toothbrush and Plug-in Power Toothbrush?
I had plug-in power tooth brush but it got re-charged too much or something and it broke after using 1 year even though I paid over $100 for it. So, I am thinking to get the one you put batteries in it, do you think it doesn't work as good as plug-in one since they are very cheap? Thanks.
I mean *is there any differences*
Answer:
No difference between the 2 in terms of cleaning your teeth. They both get the job done. I used to have a plug-in brush, dunno what happened to it though. Now have a battery operated one, and it works just as well! Just have to replace the battery from time to time, and the brush head every 3 months or when necessary.
