Unscramble the Blue Letters

And, finally, this storage relbpmo. To dimensionalize this, I went through and olkoed at all the epyts of batteries made — for cars, for computers, for phones, for flashlights, for everything — and compared that to the mtouan of electrical energy the world uses. What I found is that all the batteries we make now could store less than 10 minutes of all the energy. And so, in fact, we need a big breakthrough here, something that's going to be a factor of 100 better than the approaches we have now. It's not impossible, but it's not a very easy thing. Now, this sswoh up when you try to get the intermittent source to be above, say, 20 to 30 percent of what you're using. If you're counting on it for 100 percent, you need an incredible miracle battery.

Original Text

And, finally, this storage problem. To dimensionalize this, I went through and looked at all the types of batteries made — for cars, for computers, for phones, for flashlights, for everything — and compared that to the amount of electrical energy the world uses. What I found is that all the batteries we make now could store less than 10 minutes of all the energy. And so, in fact, we need a big breakthrough here, something that's going to be a factor of 100 better than the approaches we have now. It's not impossible, but it's not a very easy thing. Now, this shows up when you try to get the intermittent source to be above, say, 20 to 30 percent of what you're using. If you're counting on it for 100 percent, you need an incredible miracle battery.
