You can make a battery out of a lemon, a tomato, an orange or a stack of old two cent coins. And now, thanks to a miracle of modern science, you can make a battery using spit.

By the end of the year, South Australia will be home to the world's biggest battery, if Elon Musk and Tesla make good on an ambitious commitment. The battery installation will be hooked up to a 99-turbine wind farm (which is still being built) and serve as an energy reservoir to ensure that the region has enough power, even during times when power demand peaks.

Although most of the flowers were still young—little more than buds—some had reached a status worthy of peeping, with full “puffy white” blossoms. And then came a week of not wholly unexpected back-to-back hard freezes. It was early March, after all, and the National Oceanic Atmospheric Administration doesn't declare Washington free from frost risk until the end of April.

In preparation for war in 1940s, U.S. Army tanks crunched across the wild deserts of Southern California, leaving tracks that will remain for thousands of years. Jeffrey Lovich, a U.S. Geologic Survey research ecologist, has trekked through these harsh desert environs for decades, and sometimes comes across the tank- imprinted past. “It's a consequence of history,” he says.

Algae can be used for anything. You can grind it into cattle feed or squeeze it into jet fuel. You can even make it into algae butter. For now, algae-based products remain woefully expensive, but a group of California scientists is working on making them a whole lot cheaper.
