Wireless Electricity - CES 2009
 

Get charged up with Paul Hochman as he shows how wireless power works.

Look Ma...NO WIRES!

Amazing!

FINALLY

I fucking HATE wires

1st person that spouts off about Tesla should slam their nuts into a desk corner pronto.

it's a cool gadget but seems useless...

pretty cool indeed

gonna get cancer

And why would that be?

What they're doing here... isn't new.

We've been using induction for centuries, literally.

How do you think induction based cook-tops work?

How do you think transformers work- in your power supplies, computers, everything.

How do you think farmers have been stealing power from powerlines for years?

Besides which: Although Tesla pioneered wireless power, he wasn't using this type of induction: he was using the ground itself (IIRC)

His tesla coil, however, was / is an air-cored transformer, ie, induction based.

Why is that?

Imagine parking lots for electric cars equipt with that... Future looks pretty bright!

don't electric toothbrushes charge up these days without any wires?

They do?

awesome!

And my cattle does too

Yup, my sonicare does.

No metal leads on the outside of the toothbrush at all, just a rubber base.

Plunk it in the plastic holder and it charges through a magnetic/induction field.

I see problems already... It's definitely not practical for everyone.

I power my entire house off of a dynamo I installed in my Fleshlight ..

That's pretty cool. He could have said "look ma, no wires" about 20 more times.

Tesla showed this over 100 years ago


# 1893: Nikola Tesla demonstrated the illumination of vacuum bulbs wirelessly (without any wires connected to the bulbs) at the World Columbian Exposition in Chicago.

He had bulbs people could pick up, the bulbs were powered by a system on the ceiling that powered them wirelessly.

that is too cool

That's very good news, we all hate wires,especially at a computer

microwave technolgy. You will be fried between the source adn adapter.

I don't get it whats the big deal?

Induction has been around for a long time. My toothbrush charges via induction, and some electric cars use induction to charge. Telsa invented induction so what company is showing off induction at CES and claiming it as their own? We owe Tesla for alot of stuff we use every day. Everything should have his name on it.

is that still healthy?

The big deal is that it's finally being implemented on a broader, more powerful scale, without the health risks and power limitations.

In actuality what is being "celebrated" is that such technology has evolved to the point where finally it can become the primary means of powering all electronic devices instead of a random anomaly here and there.

Still pretty damn cool

Finally, a way to do it properly.

Looks like a big-ass coil to me... if it's using RF to "transmit, no, TRANSFER!" electricity it must be horribly inefficient...

Just what I was thinking... it looks like the receiver needs to be pretty close to the coil to work... and the EMF these things create can't be good for you..

Maybe you're right, but it seems to be that if this was so good it would have been implemented long ago. Maybe its just not effecient, ie, too much power loss over long range? Who knows...

It's weird how he kept saying "Transfered" instead of Trasmitted. It sounded to me like he was implying a Lossless transfer of energy. Makes me go HHhmmmm..

The word may have been important to a patent or other legal limit.

I saw that before, seems pretty cool!
