Fun fact: googling the above website actually has this post as the first result.
Anyway it’s just another scam, just like all the miracle hydrogen powered cars you used to get links about all over (in fact the website looks almost identical, probably the same scammers). If you follow the link, they are trying to sell you instructions (a regular $297 dollar value! buy in the next two days for a discount! I kid you not, there is even a ‘coupon’ with days crossed out) on how to build your own solar/wind power generators for $200 (or less!). It even comes complete with fancy ‘but wait, don’t miss this special offer’ popup when you try and leave the page.
Suffice it to say that if you really could do something like that, it would be all over the news and you would know about it. It’s not something people would flog from a shady website via google ads - the inventors would already be millionaires.
