Feb. 11 (Bloomberg) -- University of Washington Associate Professor Joshua Smith discusses smartphone battery technology on Bloomberg Television's "Bloomberg West." (Source: Bloomberg)

Works.

Our goal long-term would be to eliminate batteries altogether.

That is the dream.

What we have found is that microelectronics has become so energy efficient, the electronics that we use are becoming more efficient, but so far we have mostly focused on the fact that we get more computing for the same amount of money.

It turns out we get more computing for the same amount of energy.

I do not understand what you mean, getting rid of batteries.

What we're working on his harvesting power from the radio waves around us.

There is a team.

-- tv tower in seattle that puts out a maker walked -- megawatts of power.

What we have discovered is weekend capture that power and use it to operate devices, which means they do not need batteries anymore.

How exactly does the technology work?

What can i do with my phone if it is dead?

There will be a series of things.

The way i think about it is probably the thing that would come first is the ability to send a text, even if your battery is dead.

The scenario that comes up to me , my daughter who is 12 likes to grab my phone while i am driving and will use it to play angry birds or whatever and run the battery 20. maybe you get a flat tire or run out of gas and would like to be able to send a message to send a tow truck or whatever.

What we are working on is the ability you could take your phone if it is lately dead and send a text.

After that, we're working on things like voice, which is further off.

How far off is the technology you are working on?

I think the ability to send a text no matter what, that is something we could do -- the technology exists now.

Figuring out how to get it integrated -- the cell phone manufacturers will take several years probably.

In terms of the fundamental technology - we will have to leave it
