Zitat des Tages über Solar:
I think that, a lot of times, people have this idea that the solar system is entirely explored, that we have sent spacecraft to every planet, we've taken beautiful pictures of everything, and that it's kind of done.
Most of the oceans in the Solar System are deep beneath ice shelves.
Once solved, the severe handicaps imposed on space exploration by the weight and chemical limitations of rockets would no longer apply. The whole timetable of our conquest of the planets in our solar system would be tremendously speeded up, from hot Mercury all the way out to frigid Pluto.
Windmills and solar cells are carbon-free sources of electricity. But they are costly. If you've been investing in those, give it up. That game is effectively over.
Life is extremely resilient once it takes hold, but it requires rich chemistry, large energy sources, and stability, right from the beginning. The comparative planetology of our solar system makes it seem like those initial conditions are hard to come by.
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.
There's an idea that London is a planet on its own: that it's starting to diverge from the rest of the solar system. We need to combat that.
In my district back in Texas, significant because we have a big solar panel production plant in Keller, Texas, we have a wind turbine plant in Gainesville, Texas, up in Cook Country.
I drive a hybrid, and we've changed our light bulbs and windows and installed solar panels and geothermal ground source heat pumps and most everything else.
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.
Going to the Kuiper Belt is like an archaeological dig into the history of the solar system.
A new idea - whether it's a way to collect solar energy more efficiently or a cheaper way to desalinate sea water or a new seed to boost the amount of food we can grow - can stretch the physical resources we have, or even multiply them. And the ideas themselves don't ever wear out.
We are already witnessing a transformation in the U.S. economy to increased production of lower carbon energy through fuel switching to natural gas and expansion of wind, solar, geothermal, and other renewable non-carbon intensive energy sources.
My studio cube is an experiment in solar heating and design. The south wall is covered with glass planks that collect and distribute heat naturally to my work studio on the second level.
New technologies such as solar systems or hybrid cars aren't created overnight. By extending these tax credits we are giving this industry time to grow, branch out and succeed.
We've offered direct financial support for a range of renewable energy sources, whether it be large-scale solar, whether it be geothermal, whether it be wave power or wind power.
The Moon and Mars were the two most likely candidates for life in the solar system; what exists beyond our solar system is mere guesswork.
I ride my bike for transportation a great deal - occasionally I ride it for fun. But I also have a generator bike that's hooked up to my solar battery pack, so if I ride 15 minutes hard on my bike, that's enough energy to toast toast, or power my computer.
The key thing to understand is that solar activity causes shifts in the jet stream with consequent changes in weather patterns and triggers processes that lead to storm formation.
Shortly afterwards, I did a third one to repair the robotic arm of the station. This arm plays a very important role in the ongoing expansion of the station as well as in the deployment of solar panels.
The source of all the energy is the sun. The big challenge is, how do you use all of that energy? Solar power has to fascinate you. There have been strides to get the costs down, and if this will work, you have to get costs down so it is competitive with fossil fuels.
I've been told that I have a lot of energy. The secret is that I use renewable resources. Some days I'm solar powered. Some days I'm wind powered. And some people in this room might think I'm hybrid gas-powered. You'll just have to guess which it is today.
The green appeal of solar sailing - traveling by light, once chemical propellants have done their dirty job of orbital insertion - ought to be powerful.
Screens can work wirelessly and run on the amount of power supplied from a small solar panel and room light.
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.
I felt like I might as well have been living in another part of the solar system.
The campaign finance scandal in America is the global warming of American political life - with cash substituting for deadly solar radiation.
I think the future for solar energy is bright.
The only thing that really scales up apart from nuclear is solar power from other people's deserts.
The use of solar energy has not been opened up because the oil industry does not own the sun.
In 'Cosmicomics,' I came close to science fiction - I was inspired by cosmological subjects and the workings of the universe and invented a character who was a sort of witness to everything that was happening inside the solar system.
I've been thinking a lot about space. It was one of those slow-motion realisations how little we are, how far we are from everything else in our solar system. This idea of distance started kind of haunting me. How do you go forth and accomplish things but not end up leaving everything you started out with in the dust?
Asteroids are deep-space bodies orbiting the Sun, not the Earth, and traveling to one would mean sending humans into solar orbit for the very first time. Facing those challenges of radiation, navigation and life support on a months-long trip millions of miles from home would be a perfect learning journey before a Mars trip.
I'm sponsored by the solar company Goal Zero, and they were gracious enough to install panels on my van and a nice battery system for the inside. I have lights and a fridge inside the van. And of course I had panels installed on my mom's house.
I gained a first class degree in Physics at Imperial College London in 1968 and did research in solid state physics, but did not pursue meteorology matters until gaining an M.Sc. in astrophysics from Queen Mary College London in 1981, after which I investigated and attempted to construct theories of solar activity.
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.
