Video How It's Made Engineering

These guys took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they're there. The first time it's heard about shade balls the claim was they reduce evaporation. But it turns out this isn't the reason they were introduced.

Huge thanks to LADWP for arranging this special tour for me. Next time let's put the GoPro on the submersible!

The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the main reason they are on the reservoir is to block sunlight from entering the water and triggering a chemical reaction that turns harmless bromide into carcinogenic bromate. This effect occurs with prolonged exposure to bromate so regulators insist that levels be kept below 10 microgram per liter on average over a 12 month period. (read more...)

Tesla chief executive Elon Musk told employees that he will increase scrutiny of the company's expenses in his latest initiative to cut costs at the electric carmaker. Tesla earlier this month closed a $US2.7 billion ($3.93 billion) offering of stock and convertible notes, giving it much needed cash as it ramps up production.

Mr Musk in an email to employees, seen by Reuters, said its net proceeds from the offering gave Tesla only 10 months to achieve break-even at the rate it was burning cash in the first quarter. (read more...)
