Future of Hydrogen Economy is Ammonia?

Hydrogen economy? Ammonia.

Anyway, I ran across a story. I just wanted to put it on people’s radar. I created a bit.ly link for the article. And I don’t know why I made it upper and lowercase. I shouldn’t have. But so it’s a bit.ly, bit.ly/NH3-Cracking. So cracking. NH3 is the chemical formula for ammonia. And this is an article which was just published that says: “A hydrogen breakthrough could be a game changer for the future of car fuels.”

begun learning about solar power

i have begun learning about solar power. Solar power is electricity converted from light by solar cells. I want to power a small computer using a solar panel. I need to figure out: Image

  1. how much power the computer needs
  2. how big my batteries need to be
  3. how to charge the batteries using the solar panels
  4. if my battery voltage is different than my computers  voltage, what might i need to add or change to give the right voltage to the computer
  5. how much power can i save compared to when i was not using solar power
  6. would a smaller computer be more energy efficient than a bigger one
  7. how do i measure work per energy unit for each computer

I need batteries because solar energy comes from the sun and if, say a cloud passed there would suddenly be less power , the when the cloud went away, there would be more power. Really only appliances made to withstand these rapid power swerves can withstand them for long, however, if you just charge the batteries with the solar power then you can discharge continuous power from the batteries for the computer.

Pacific Northwest Eclipse Times, Dec 10

My sister passes along the OMSI planetarium manager’s  useful local timeline:

“For the Pacific Northwest viewers, the penumbral eclipse begins at 3:33 a.m. PST and the umbral shadow takes a small, dark bite out of the left edge of the moon starts at 4:45 a.m. PST. For 66 minutes of the partial phase, the darkness engulfs more of the moon’s disk as it slides into the shadow. The partial eclipse ends and totality begins at 6:06 a.m. PST and the point of the greatest eclipse occurs at 6:31 a.m. PST. The eclipse’s total phase will lasts for 51 minutes. The moon will be only 6.5 degrees above the north western horizon at the instant of the greatest eclipse.”

So setup your camera tonight!
