I personally do not use green web hosting due to the fact that there’s no green hosting companies that can provide dedicated servers that match my requirements but if you are looking for a cheap shared hosting for your next web project, you might want to consider the Top 7 best green web hosting companies from our sister blog Keetsa:

Check out this really cool DIY on how to make a vertical wind turbine.  This thing can produce some good amount of electricity for under $300.

With this one I am hoping to get the 100 watts.

Here is how I did it.

First we need:
–5 pvc tube. size 3″X10′ (hardware store)$48

–3 bike wheels. size 12″ (junk yard or ask your kid to use their bikes for a minute) maybe $5

–Ametek38 volt (ebay or surplus store) $60 (a problem with ametek, it needs 700 rpm to reach 14.1volt.

–Or buy windblue alternator (ebay) $250 it will only need 200prm to reach 14.1 volt

–1 square foot 1″ plywood or anything 12″ diameter (laying around)

– 3 X 2×4 X 12′ studs (from lumber store)$11

I am not going to name the tools, but I used the usual tools.

Engineers at Oxford University have come up with a new innovative concept for underwater turbines that use 60% less manufacturing and 40% less in maintenance costs.

This type of new underwater generator involves the THAWT device.  I believe these types of underwater turbines and ocean wind turbines combined will soon be everywhere in the ocean to generate over 90% of our electricity.

The THAWT is considered to be a “second generation” turbine as opposed to the first generation models that resembled windmills. It consists of a cylindrical rotor that rolls around its long axis with the flow of water, instead of turning at right angles. Promising to be more efficient and powerful than other underwater turbines, each THAWT is predicted to produce 12 megawatts of energy - enough to power 12,000 family homes and significantly more than other underwater turbines of today.

There’s has been no better time than today to learn about saving energy with the eco-friendly wind powered toy car.  We suggest you to get one for your child for the best learning experience.  Actually, I might get one myself it’s so cool…

This new educational kit lets you explore the mechanisms involved in harnessing the alternative energy of wind power. The windmill features loop-wing design that can be rotated by the slightest breeze. You can also run while holding it to generate wind artificially. The kit comes with a rechargeable vehicle that uses power generated by the windmill, running for 1-2 minutes for each 5-10 minute of charge.

Thinking of making your own box kite?  Here’s a cool set of photos you can refer to making your own box kites!

I’ve been making these [box kites] for few years, and tomorrow I’m getting a bunch of people to make them at gas works park in Seattle. So I figured I would spice up my usual instruction set and put it on flickr.

Wow, here’s a cool firewinder outdoor lighting that runs on pure wind power!

Firewinder® is a sculpturally designed outdoor light, which harnesses the wind no matter from which direction it blows creating a beautiful upward spiralling light - every time the wind blows.

Supposedly, these new AeroCam wind turbines are more efficient than ever and you can put them on the roof of your house for the most efficient wind electricity production ever.  If you can afford the high price tag of $250,000 USD for a 250kW system, it might be well worth your money than getting solar panels for your roof.

I have always been fond of different windsurfing gadgets people bring to have fun over at Ocean Beach, here’s how to make your own skateboard-turned-windsurf thingee.

If this goes on sand, I might build one.

Here’s my contribution to the movement, a land windsurfer with a 3.6 meter lugsail.

It sails just exactly like a regular windsurfer. Sail tuning is a little different, due to having four corners to adjust rather than the old three. Study up on lugsail tuning.

Here’s a cool tent that can power your gadgets through its wind turbine and solar panels at the top of the tent.

Although this concept looks to be for commercial use right now, they should really make a mini-version for consumers like me who take their tent to the beach. Perhaps some bigger, lighter solar panels covering the whole 1/3 of the tent might be good for solar beach laptoping.

you’ll be able to power your phone at a dedicated renewable energy tent. Built by Orange, the ‘recharge Pod’ is a seven-metre high tent with 500 watt solar panels and a 500 watt wind turbine on the roof that’ll generate electricity for dead mobile phones.
