Two leading fuel cell manufacturers, Massachusetts-based Nuvera and Albany, N.Y.-based Plug Power Inc., will each receive $650,000 from DOE’s Office of Energy Efficiency and Renewable Energy. The companies will provide matching funds and labor of their own. A PNNL team led by Brooks will oversee and evaluate the two-year program.

Industry officials estimate that approximately 300,000 refrigerated trucks with auxiliary power units are on the road in the United States. By replacing the small diesel engines with the more efficient fuel cell, users will see fuel savings of approximately 10 gallons a day per unit, in addition to reduced emission of pollutants and significantly quieter operation.

People need to travel →

Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one’s lifetime.

1953 Ford Jubilee: Anyone interested in a tractor? Good condition, running and everything works, 3-point lift, brush hog, scraper/snow blade… fully working, but it is also a collector’s item if you’re into antique tractors.

Getting to space is easy. Staying in space is hard. →

The reason it’s hard to get to orbit isn’t that space is high up. It’s hard to get to orbit because you have to go so fast.

…

The speed you need to stay in orbit is about 8 kilometers per second. Only a fraction of a rocket’s energy is used to lift up out of the atmosphere; the vast majority of it is used to gain orbital (sideways) speed.

Parkour is about taking the road less travelled by, and choosing the harder path every time. It’s about understanding that excellence does not arise from simply doing what is convenient or what pays well or what advances your personal career. The Olympic Games are sponsored by Coca-Cola and McDonalds. That’s not right.

Have principles. Stick to them. Because if you don’t stand for something you’ll fall for anything.

In struggle there is magic →

Published September 25, 2013  ·  All posts on Sep 25  ·  ,

Western culture has things a little backwards right now. We think that if we had every comfort available to us, we’d be happy. We equate comfort with happiness. And now we’re so comfortable we’re miserable. There’s no struggle in our lives. No sense of adventure. We get in a car, we get in an elevator, it all comes easy. What I’ve found is that I’m never more alive than when I’m pushing and I’m in pain, and I’m struggling for high achievement, and in that struggle I think there’s a magic.

Ever notice how drinking’s like war?
Cup o troops oe’r the guns
Til the end of our health
A campaign ‘gainst myself
Armed with bourbons and scotches and rums
