Mariah Power, a small wind turbine manufacturing company, has created a wind speed measuring app for the iPhone. The basic idea of course, is to let interested users measure wind speed, and see if it would suit their need for a small wind turbine.

Generating electricity by harnessing the power of the wind in the most stylish possible way, here’s another rooftop wind turbine that offers a cost effective energy source for domestic, community and industrial use.

Designed by Cascade Engineering to be environmentally  sustainable, the Swift Wind Turbine uses a variety of patented technologies that makes it both safe and silent, and has a very sleek aspect. As for how effective it is, in just four years it becomes carbon and energy positive.

Aesthetically pleasing, the wind turbine is suited for both urban and suburban settings, and features a system that makes it easy to install and operate for every user. Here are more specs about it:

• Blade/Ring Diameter: 7 feet
• Minimum clearance from roofline: 2 feet
• Rated power output: 1.5kW @ 14 m/s
• Annual Power Supplied: up to 2000 kWh
• Electric power: 240VAC, 60Hz output voltage
• Noise: less than 35 decibels for all wind speeds
• Quiet mast mounting technology eliminates unwanted vibration to building/home

The Windspire vertical wind turbine by Mariah Power is a noiseless way of powering your own home for cheap in a sustainable way. Using wind power to spin, this 29.5-foot-tall vertical axis wind turbine (VAWT) it outputs 1.2 kW, will cost you some $5,000 and is able to provide 25-30% of the power needed in a typical house. Looking quite attractive it also packs a Wi-Fi transmitter so that you can monitor it online using your own computer. Count the 30% government rebate to the whole thing and you’ll end up with quite a deal.

Meanwhile Mariah Power is working on a larger 3 kW Windspire that – they say – will supply most of your house needs. – via Dvice

What if those more than 5 million heavy duty trucks rolling up and down just the U. S. highways, would be powered by an engine wit 30-percent better fuel mileage, that doesn’t have pistons and needs no lube?

Such a truck gets on average a 7 mpg and with oil, diesel and gas prices only going up, someone had to come up with a solution. Turbine Truck Engines may have good news for the big fellas, a new engine dubbed Detonation Cycle Gas Turbine (DCGT) that:

• will use 30-percent less fuel
• will reduce emissions by 30-percent
• will be able to use all sorts of fuels – biofuels, hydrocarbon fuels, H and even synthetic
• will have fewer moving parts, which will reduce maintenance costs
• will use no lube oil, filters or pump because it has no pistons or valves
• will be lightweight : only 2lbs / hp

All they need is investors.

Where’s Pickens when you need him because having this technology in all those French and Spanish trucks idling and on strike, would be great. Right?
