Meet LIAM: A Mini Windmill Ideal for Any Home

by , 02/17/15

Rotterdam company Archimedes has created a small windmill that can be installed on just about any roof, anywhere. Meet LIAM: a quiet, affordable wind energy source that’s ideal for urban settings; it’s compact and its yearly output averages between 300 and 2500 kilowatts, depending on wind speed and roof height. You can also place more than one of these windmills on your roof for added power, or combine them with solar panels so you have a backup source of energy on still days. The price in holland will be € 3,999 (approximately $5,452 USD), and a mini-LIAM will soon be available as well. These turbines will be available for consumers to order as of June 1st, 2014.

    Thanks. But i think i’ll stick to the Honeywell turbine, that costs about the same and covers my homes annual consumption of 900kWh:

    Even at 2500kWh per year this think will only save me a lousy 625 Euros (using costs of 25 cents per kWh). Which means that amortization has a minimum of 9 years. Probably more like 20+ years. And as always it’s only working out if the damn thing doesn’t break. I’m sure it doesn’t have a 20 year warranty.

    Its a great innovation, no doubt about it. But my only issue with this is it may not be “bird friendly”. I have a lot of pigeons that are very curious and I dont want them to get hurt.

    Hey guys, check your units. I believe you mean 300-2500 kilowatt-hours a year, which with a 40% capacity factor puts this unit at about 85 to 700 watts.

    The euro price has 21% tax. So you need to reduce the dollar price with at least this %.

    You can buy a 2kw turbine right now for less than $1000 on Ebay… if my math is correct that’s WAAAAAY cheaper for a higher kwh turbine. I’m sure someone will correct me if I’m wrong.
    This maybe smaller, cant really tell from pics but seems to me unless your living in a city that there’s no reason for this.

    affordable???? are you serious???and we can place more than one of these???you guys are funny!

    Neat idea, but by my calculations using BCHydro’s rates ( – my local utility) means that at 1400kw produced, that I would save $105 in electricity, and at 2500 kw produced, I would save $188 in electricity. Making the time to pay back my $6106 (CDN) investment take 58 years @ 1400kw produced or 32.5 years @ 2500kw produced.

    This windmill will need to significantly reduce its price to become cost effective.
