Quote of the Day
When you look at the stars and the galaxy, you feel that you are not just from any particular piece of land, but from the solar system.
There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.
It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.
Solar power is the last energy resource that isn't owned yet - nobody taxes the sun yet.
'Easter' is a movable event, calculated by the relative positions of sun and moon, an impossible way of fixing year by year the anniversary of a historical event, but a very natural and indeed inevitable way of calculating a solar festival. These changing dates do not point to the history of a man, but to the hero of a solar myth.
The planet Earth, though not threatened with destruction by man-made global warming, is by no means indestructible. There are many unpredictable events within our solar system, and still more outside it, that could make Earth uninhabitable by humans.
When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.
Already renewable energy advocates are noting that the 42 miles of above-ground right-of-way between Yosemite and the city could be fitted with enough solar panels to generate at least 40 megawatts per year - a proposal the San Francisco Public Utilities Commission has never seriously considered because they currently aren't required to do so.
I felt like I might as well have been living in another part of the solar system.
I hope climate science becomes the big thing. And then what I want is electrical engineers to solve the world's energy problems, energy distribution problems. I want mechanical engineers to make better transportation systems. I want chemical engineers to develop better solar panels, and so on.
Solar power is clean, renewable and cost effective, but it also needs time to develop.
J. D. Hayworth
We need to bring sustainable energy to every corner of the globe with technologies like solar energy mini-grids, solar powered lights, and wind turbines.
We live in a world bathed in 5,000 times more energy than we consume as a species in the year, in the form of solar energy. It's just not in usable form yet.
Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.
It's time for the human race to enter the solar system.
The world, when you look at it, it just can't be random. I mean, it's so different than the vast emptiness that is everything else, and even all the other planets we've seen, at least in our solar system, none of them even remotely resemble the precious life-giving nature of our own planet.
The Moon is a ball of left-over debris from a cosmic collision that took place more than four billion years ago. A Mars-sized asteroid - one of the countless planetesimals that were frantically churning our solar system into existence - hit the infant Earth, bequeathing it a very large natural satellite.
Compared to coal, which generates almost half the electricity in the United States, natural gas is indeed a cleaner, less polluting fuel. But compared to, say, solar, it's filthy. And of course there is nothing renewable about natural gas.
The solar system should be viewed as our backyard, not as some sequence of destinations that we do one at a time.
Neil deGrasse Tyson
Just think: in all the clean, beautiful reaches of the solar system, our planet alone is a blot; our planet alone has death.
When wireless cellphones first came out, analysts predicted that at peak, it would only replace 5% of landlines. They said the quality wasn't good enough. Clearly that was improved. I think you'll find a similar thing in solar.
Then, I realized that there is an indigenous presence in the Solar System. It's us. So, then, I got to wondering what would happen if a more technologically advanced society moved next door to us, the way we moved next door to the American Indians.
If anyone has a vested interest in space solar power, it would have to be me.
Consumers used to think they had to compromise with solar. It was, 'Okay, I'm doing the right thing for the environment; it's cool to see the panels. I have to compromise on the cost and convenience side.' And now they no longer have to. On the cost side, it's cheaper, and on the convenience side, we set it all up.
We believe widespread adoption of home solar will significantly improve life in cities by phasing out polluting coal plants, eliminating miles of ugly new transmission lines, and ensuring cleaner, healthier lives.
