Quotes About Solar

A manned mission to Mars, called for by the first President Bush in a moment of passing giddiness, was quietly dropped when someone worked out that it would cost $450 billion and probably result in the deaths of all the crew (their DNA torn to tatters by high-energy solar particles from which they could not be shielded).

The upward flow of ancient heat to the Earth's surface is measured in tens of milliwatts per square metre; the flow from the Sun above is measured in hundreds of watts per square metre.

The point to remember, of course, when considering the universe at large is that we don't actually know what is in our own solar system. Now

Just think about how many landowners, utility companies, and local and state governments you'd need to bring together to build power lines that could move solar energy from the Southwest all the way to customers in New England. Merely picking the routes and establishing rights-of-way would be a massive undertaking; people tend to object when you want to run a big power line through the local park.

To avoid a climate disaster, we have to get to zero. We need to deploy the tools we already have, like solar and wind, faster and smarter. And we need to create and roll out breakthrough technologies that can take us the rest of the way.

But Germany produced about 10 times more solar in June 2018 than it did in December 2018.

The United States gets around 20 percent of its electricity from nuclear plants; France has the highest share in the world, getting 70 percent of its electricity from nuclear. Remember that by comparison solar and wind together provide about 7 percent worldwide.

The share of global power that comes from burning coal (roughly 40 percent) hasn't changed in 30 years. Oil and natural gas together have been hovering around 26 percent for three decades. All told, fossil fuels provide two-thirds of the world's electricity. Solar and wind, meanwhile, account for 7 percent.

I am talking about the responsibility of the poet, who is irresponsible by definition, an anarchist enamored of a solar order and never of the new order or whatever slogan makes five or six hundred million men march in step in a parody of order.

In theory, solar storm activity could act like an EMP, damaging electronic equipment and causing power surges. And we've just experienced the solar storm to end all solar storms.", FADE by Kailin Gow

I live out of my van, which gives me a first-hand appreciation for power and lighting. A few years ago, I rebuilt the interior of my van to include solar panels and a battery that powers LEDs for lighting and allows me to charge my phone and laptop.

I was inspired to see leaders from Paris, New York City, San Francisco and Vancouver, B.C. rolling up their sleeves to create clean and safe transportation systems; make homes and buildings efficient, comfortable and affordable; and ensure more of our energy comes from clean sources like wind and solar.

The green appeal of solar sailing - traveling by light, once chemical propellants have done their dirty job of orbital insertion - ought to be powerful.

We're leading a fundamental shift from centralized energy to distributed energy. Energy will go in that direction, just like mainframe computers went to client servers, then to the Internet. I believe in solar, and the macro trends are just too undeniable.

I think, in a lot of places, the solar panels are a badge of honor; they're trendy. If you go to Hawaii or Japan, people even install fake solar panels because it's cool and it's popular. And so I think solar panels have gotten a lot more attractive. They're sleek, black, they look good on a roof.

Our expertise is solar energy and we don't want to focus on other forms and we never push for solar form everywhere like say in upper hill areas where eco-hydro or biogas is more viable.

Solar panels require sixteen times more materials69 in the form of cement, glass, concrete, and steel than do nuclear plants, and create three hundred times more waste.70

During the eleven-year sunspot cycle, for example, solar flares can send enormous quantities of deadly plasma racing toward Earth. In the past, this phenomenon has forced the astronauts on the space station to seek special protection against the potentially lethal barrage of subatomic particles.

The deep space transport uses a new type of propulsion system to send astronauts through space, called solar electric propulsion. The huge solar panels capture sunlight and convert it to electricity. This is used to strip away the electrons from a gas (like xenon), creating ions. An electric field then shoots these charged ions out one end of the engine, creating thrust. Unlike chemical engines, which can only fire for a few minutes, ion engines can slowly accelerate for months or even years.

There are many advantages to space solar energy. It is clean and without waste products. It can generate power twenty-four hours a day, rather than just during daylight hours. (These satellites are almost never in the shadow of the Earth, since their path takes them considerably away from the Earth's orbit.) The solar panels have no moving parts, which vastly reduces breakdowns and repair costs. And best of all, space solar power taps into a limitless supply of free energy from the sun.

The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

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.

Lyapunov time sets a horizon beyond which acceptable prediction becomes impossible. For a chaotic electrical circuit, the horizon is something like a thousandth of a second; for the weather, it's unknown but seems to be a few days; and for the solar system itself, five million years.

Humans belong to the group of conscious beings that are carbon-based, solar system-dependent, limited in knowledge, prone to error and mortal.
