I hate to post late on this but. The Steve Irwin crew needs to get their head out of their bums. They are a hazard in the ocean and need to be put in jail. Normal sailors don't get barred from ports for being nice in international waters. What these people are doing is terrorism and needs to be treated as such. I don't support the Nishin crew harvesting so many whales, but being terrorists is not going to help anything.

seems like an obvious lie. they've got the small fast boat, the whalers have the big slow boat, and the protesters are getting close intentionally to interfere with the whaling.

Earthrace fans and viewers might check out this Earthrace eulogy page. It's got some history, photos, and a eulogy.

Hello yachtwork, and welcome to PF. You will find quite a few Earthrace fans here.
Normally we would be obligated to delete your post as spam, but given your unique role in this project and the quality of your website [I think "cool" was the word used], we are making an exception. I assume that you are the same Scott cited as the Earthrace 2007, chief engineer; author of the webpage? That was one very cool boat. It was a heartbreaker to see it destroyed. Was there only one built? My first thought when I saw the news video was that this might have been a second boat having the same design, but no such luck. Are there any plans to build another?

I was wondering about this comment (sorry, just seeing this thread for the 1st time now). Is it nearly neutral because, if you didn't burn the biomass as fuel then it would still decay and release nearly the same amount of CO2?Ivan Seeking said:

Atmospheric carbon dioxide is consumed by the plant used [rape seed, soybean, cotton, palm... or best of all, algae], order to grow, and then released again when the oil from the plant is burned as a fuel. So there is no net contribution. We only get as much out as went in.
With petroleum products, we are releasing carbon that was sequestered millions of years ago - technically carbon neutral, but not so for our purposes because that carbon was safely locked away.
Oh, if you meant why NEARLY so and not completely, IIRC, there is a slight amount that is released from the soil as a function of farming practices. We also have to consider how the fuel was processed. Electrical energy was probably used to power the processing of the fuel, and petrodiesel may have been used at various times to run farming equipment.

I was wondering about both, but mostly why it is neutral rather than why not exactly neutral. Thank you.
