Wow, the Science Guy is really making it happen!!! Check out the whole conversation here.

Healthy competition: I’ve got to crush Ed Begley! He lives down the street. We compete over our houses, but we’re friendly. We go to lunch at the local vegan place.

Best addition: My solar panels. They are 4-kilowatt panels. I have 24 of them, each 2-by-4 feet. They cost $32,000 to buy and install, after an 18% tax rebate.

Lab work: I drink my lemonade in a beaker.

Giving back: My house is attached to L.A.’s main power grid, but I make more power than I use. So, I send my excess energy back to the grid and my bill is just $7 a month, which is a connection charge.
