| Sun - Wind - Strength: Bike Add-On Creates Power |
| Written by Hank Green | ||
| Tuesday, 26 June 2007 | ||
 For those of us who are interested in distance travel without fossil fuels, but can't do without our cellphones, iPods and laptops, designer Paul Smith has put together the Navitas. The Navitas can charge it's on-board, 24-volt battery in three different ways: Strength, Sun and Wind. The device, which I imagine doubles as extra storage space as well, uses the attached rear wheel to charge the battery when the bike is moving. Then, once stopped, the Navitas can be snapped off the bike and the rear wheel becomes a wind turbine, while a square foot of solar panels pops out for good measure. It's good to see someone thinking about these kinds of things, but it won't be all that useful until there are a lot more distance bike travelers on the road.

With the extra effort involved in towing the trailer around, you might as well install a generator in the wheel instead, a lot simpler.
And as Tenbees pointed out, if you left it in the car park, it wouldn't be there when you came back. Or someone would have bent the wind turbine pole in half (we have a lot of vandals in the UK).
Better options
written by Andrew Stannard , June 28, 2007
You can bike bike hubs with a built in dynamo, a much smaller frame mounted device to work with one of these would seem a much more practical option for the majority of people.
It does have luggage space though which is a bonus, I would think a trailer design that is mounted through the rear wheel axel would be a beeter design for a mono wheel trailer.

People just don't like to write comments, they like to read posts therefore there is no need to fake posts. Take ProBlogger for an example sometimes he is left with 20 comments a day sometimes he is left with 200 comments a day even tho he is getting 25K-30K visitors . http://www.averagepenisenlargement.com

My main concern is that you can't guarantee every page of your website will be included in the SERPs. Considering I'm constantly adding new products to my company's website, I need to be sure that customers can find them as soon as possible.http://www.seoptimizerz.com

written by SEO , July 28, 2007
If you're a blogger (or a blog reader), you're painfully familiar with people who try to raise their own websites' search engine rankings by submitting linked blog comments like "Visit my discount pharmaceuticals site." This is called comment spam, we don't like it either, and we've been testing a new tag that blocks it. From now on, when Google sees the attribute (rel="nofollow") on hyperlinks, those links won't get any credit when we rank websites in our search results. This isn't a negative vote for the site where the comment was posted; it's just a way to make sure that spammers get no benefit from abusing public areas like blog comments, trackbacks, and referrer lists. http://www.gordoniihoodia.net

Breast Enhancement - Enhance Your Bust Size Naturally
Women are always concern about beauty and physical appearance. Breast size is one factor that affects the physical appearance of most women. Women with big breasts are always regarded as sexy and adorable. In today's modern world women are more open to take the necessary steps to improve their appearance. If you are not satisfied with your breast size, there are ways on how to enhance your bust size and increase your self confidence. If you have small bust size, you are often the subject of teasing leading to low self-esteem. You feel insecure and do not feel good about yourself. The good news is that you do not have to feel bad about yourself and suffer all those teasing because you can do something to enhance your bust size. Although breast enhancement surgery or breast implants is a very common cosmetic surgery now, this is not the only way to enhance your bust size. Before taking the drastic steps of surgery which could have irreversible side effects, it is an option to try other methods to enhance bust size naturally.
