I have difficulty concentrating.

I was concentrating on reading.

We're not just concentrating on resistance.

Being generous to concentrating solar power,

In principle, you make those trees into biological photovoltaic cells.

Concentrating on resistance, there's something wrong with that.

Bioenergy is taking the sun, concentrating it in amoebas, concentrating it in plants, and maybe that's why you get these rainbows.

But geothermal, concentrating solar, advanced photovoltaics, efficiency and conservation.

It might be problems with concentrating on a theme.

All the world's photovoltaic solar panels generate as much electricity as two coal power plants.

We do not become good drivers by concentrating on driving as such.

It's pretty late already and you keep on concentrating, stepping, stepping, stepping.

Turns out it's the spot that lights up when people are concentrating.

And a fourth supply side option concentrating solar power in other people's deserts.

In 2000, I began documenting global health issues, concentrating first on AlDS in Africa.

Religious teaching, this is where we've gone so wrong, concentrating solely on believing abstruse doctrines.

There are twelve people in here concentrating on this case. Eleven of us didn't think of it either.

Concentrating solar power in deserts delivers larger powers per unit area, because you don't have the problem of clouds.

As you can see, there's me in my early, pre marriage days with a brown beard, and little Derek concentrating there.

The Solar Challenger was made to serve as a symbol that photovoltaic cells can produce real power and will be part of the world's energy future.

These are concentrating solar, renewable energy plants, linked in a so called supergrid to supply all of the electrical power to Europe, largely from developing countries high voltage DC currents.

Unless you look at the system as a way to treat waste water, sequester carbon, and potentially for photovoltaic panels or wave energy or even wind energy, and if you start thinking in terms of integrating all of these different activities, you could also include in such a facility aquaculture.

But what's beginning to happen is because these geeks are all getting together, because they are highly qualified for computer programming and it is highly remunerated, as well as other very detail oriented tasks, that they are concentrating geographically and finding like minded mates.

So going back to what I was saying before about all power being produced well, other than photovoltaic being produced by this boiling of steam and turning a turbine, that's actually not that efficient, and in fact, in a nuclear power plant like this, it's only roughly 30 to 35 percent efficient.

In Afghanistan, it could have meant instead of concentrating on the big presidential and parliamentary elections, we should have done what was in the Afghan constitution from the very beginning, which is to get direct local elections going at a district level and elect people's provincial governors.

That may be a little confusing at first because it goes twice as fast, but we're really concentrating on the growth of the run time so that even if it is going twice as fast as the worst case, if we double the number of elements in the list p, the run time is also going to double.
