Small-time Wind Energy – Too Good to be True?


When I heard the government had created incentives to encourage individuals to install small wind turbines at their homes and businesses, I was stoked. Perhaps the incentive would bring alternative energy into people’s living rooms, so to speak – out of the abstract and into real life. But a recent review of one wind power product – the Honeywell Home Wind Turbine by EarthTronics – has me wondering: will consumer disillusionment by potential flaws in small-time wind energy sources impede the renewable energy movement?

The EcoGeek reviewer watched Honeywell’s promotional video, which describes the six-foot-wide turbine as being able to generate more than 1,500 kilowatts per year, meet 30 percent of consumers’ energy needs (when run in conjunction with a fluorescent light bulb, which comes with the turbine), and pay for itself in one to three years (in many states). The turbine costs $4,500.

The EcoGeek reviewer’s beef with Honeywell’s claims was, primarily, that the promo video did not qualify its figures. It should have mentioned, for example, that it its definition of the “average household’s energy consumption” as being 10- to 11,000 kilowatts per year – lower, the EcoGeek reviewer believes, than the energy consumption of households most likely to purchase the turbine. Moreover, with an initial investment of $4,500, and an anticipated electricity cost of 12 cents per kilowatt in 2010, how can the turbine pay for itself in just three years? (At 12 cents per kilowatt and, say, 1,580 kilowatts per year, the turbine would only produce $189.60 in electricity per year – a rate at which it would take consumers 23 years to pay off the $4,500.)

The reviewer goes on to imply that emerging “everyday Joe” renewable energy sources may just be fads, comparable to those of the computer industry in the early 90’s (consumers plopped down money for the latest, greatest technology, which turned out to be obsolete). This conclusion is understandable, given his take on the Honeywell turbine. Let’s just hope that the wind energy industry will be similar to the computer industry in other ways: able to make progress as technology improves, to become a household name, and, ultimately, to secure a lasting place in the renewable energy industry worldwide.

  1. Good day,

    I’m happy to chime in.

    As VP of Business Development and Marketing at WindTronics, I believe these comments assume same old same old, but there is nothing traditional about this technology. As per our web site, “the Honeywell Wind Turbine’s (HWT)Blade Tip Power System (BTPS) replaces the traditional gear box, shaft and generator of typical wind turbine technology. The Honeywell Wind Turbine’s gearless Blade Tip System creates a “free wheeling’’ turbine, generating energy from the blade tips (where the speed lies) rather than through a mechanical center gear”.

    I’d be pleased to share footage from a wind tunnel demonstration of how the system operates at 8mp when traditional turbines are just kicking in…the velocity of the HWT is off the charts.

    WindTronics was created to make Wind Energy Generation affordable and efficient. This required a complete redesign. That’s what we’ve done and yes we come to the cusp of maximum efficiency which was our plan.

    In regards to payback, DOE states as average power consumption is 11,000kWh. At 2000 kWh in Class 4 wind, this represents 18%. No doubt Federal, State and Utlity rebates play a significant role in the payback equation, but thankfully we have these rebates and incentives to help us make a difference.

    Think about magnets at the blade tips, no gears or shafts, startup at 1mph and the physics of weights on the blades tips.

    We undertsand that small wind has disappointed to date. We didn’t set out dressup exisiting technology, we literally turned existing technology inside out.
