A couple of weeks ago, a colleague of mine was reading an article about Tesla's new gigafactory that they're going to build to manufacture batteries. It was mentioned that the entire roof of the facility would be covered in solar panels to offset the running cost. One hapless commentator then posted this :
"D'uh - solar panels only work in the day time - what's the point of that?"
To which the first, only, and best reply was:
"I know. Wouldn't it be amazing if there was some way to store all that power generated in the daytime so it could be re-used at night?"
Well - I thought it was funny.
But it did raise an interesting point about internet trolls - how can you tell nowadays if the commenters are trolling, or if they really don't know the answer to the question they're posing?
