An interesting vertical wind turbine and solar power unit that’s intriguing gets coverage in the Jamaica Gleaner due to some support and interest it is getting in Jamaica.
It seems to be $3,000 a unit:
“‘One of the cries from Jamaicans is the need for alternatives, and the SolarMill goes and takes the solar installation one step further, because when the sun is not out the wind is still blowing. So it really gives you more power for your dollar,’ she asserted.
Tomblin said this product was a distinct solution for the market and customers were already asking for it.
President of WindStream Technologies, Daniel Bates, said the SolarMill would provide a viable option to complement energy needs in the country, adding that it could be utilised by residential and commercial customers.”
I perused the PDF documents pretty quickly. It looks like you’d need 3-4 of these to cover a household, but the wind/solar combo is intriguing in that it allows you to continue making power at night.
Is it cost effective, though, compared to just going all solar and tying into the grid? I can’t quite see from the info provided. But for a non-grid situation, or rural Jamaica with low-power needs and varying power availability (and given high island Caribbean power costs due to most power being made with imported fuel), coupled with a payment plan, items like this could gain some traction. I’d still want to see more info.
Incidentally, Windstream’s site is everything I hate about many kit-oriented alternative energy sellers. It does everything it can to avoid telling you the cost. In this day and age, people should be able to get on, see what it costs, click, and buy. End of story. If you’re honestly invested in, as the site claims, ECOnomical Energy (heh), then stop being dodgy on your costs. If SpaceX can be upfront about space launch costs, you can be about power generators.
Unless you’re charging some customers more than others who want flagship ‘look at us, we’re ECOnscious!’ like the touted embassies on their page.
