Solar Power: How to Win the West
As the railroads shaped the American West in the 19th century, a new electrical generating and transmission system for the 21st century will leave its lasting mark on the desert.
The sun-baked desert of the American southwest is the most obvious place for a large solar energy infrastructure, says Jon Christensen, executive director of the Bill Lane Center for the American West at Stanford University. "We need alternative energy sources badly, and to really take advantage of them we need to be able to move electricity around far more readily than we can now. The western power grid is a fragmented hodgepodge. It needs to be much better integrated. And that is going to require major power lines across the West. Trade-offs will have to be made. ..."
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
Giving our solar system a "slap in the face."
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
The 116th Congress is set to break records in term of diversity among its lawmakers, though those changes are coming almost entirely from Democrats.
- Women and nonwhite candidates made record gains in the 2018 midterms.
- In total, almost half of the newly elected Congressional representatives are not white men.
- Those changes come almost entirely from Democrats; Republican members-elect are all white men except for one woman.
