There is a fine line between radiation being your best friend or your worst enemy.
I've been very passionate about renewable energy for many years, particularly solar energy and its capacity to bring abundant clean, sustainable energy to millions around the globe.
A utility can handle up to 20% of production from solar and that helps the grid because it produces electricity when needed. Solar power peaks in the middle of the day and that's also when air conditioning is running and businesses are operating, so power production matches usage.
The public has an incredible capacity for appreciating the wonder of our planet, our solar system, our universe.
Going to the Kuiper Belt is like an archaeological dig into the history of the solar system.
As a kid, I became a total SF geek. It started in the 5th grade with Asimov's 'Lucky Starr' series of what would now be called 'young adult' novels of adventures in the solar system.
The solar system should be viewed as our backyard, not as some sequence of destinations that we do one at a time.
The Department of Defense, the largest single energy consumer in America, is bullish on solar.
What the Ten Million Solar Roofs Act does is provide consumer rebates for the purchase and installation of solar systems.
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 Venus transit is not a spectacle the way a total solar eclipse is a spectacle.
Titan is Saturn's largest moon, and, until Cassini had arrived, there was the largest single expanse of unexplored terrain that we had remaining in our solar system.
There are better alternatives... Australia should be exporting its solar technology, not its uranium.
Fossil fuels are raw materials that have to be extracted and processed. Wind and solar energy are different. The only costs associated with them are technological.
Producing fuel cells and solar panels requires high tech facilities and produces high paying jobs. The industry is booming in Arizona. The state already has about 100 firms in the solar industry and has grown 20% since 2003.
I hope that by 2050 the entire solar system will have been explored and mapped by flotillas of tiny robotic craft.
I felt like I might as well have been living in another part of the solar system.
If anyone has a vested interest in space solar power, it would have to be me.
The solar system can support a trillion humans. And then we'd have a thousand Mozarts and a thousand Einsteins.
The Saft America plant, a giant 235,000-square-foot mass of concrete, is a modern marvel: its roof covered in row upon row of solar panels, embodying the renewable future that the batteries manufactured within are meant to sustain.
