I got this video from Popular Science where you can read an interesting article on the subject. At Steampunk Fusion I have a look at whether this is a scam or could it really work. The short version: the engineering is very difficult but it could work.
According to FTC regulations I am required to disclose any material benefit I receive from any blog post.
I get paid from Amazon if you order from any of the links provided. I will give you an honest opinion of any products I have ordered if I blog about them.
If you don't trust me read the Amazon reviews. If there is no review you are on your own.
If you pay me enough and promise to cover my lawyers fees I may say something nice about you. Or I may not. Enough is generally more than you can afford. Unless you have a a really really big bank account or more that a few large gold bars under the mattress.
If you do pay I expect to be transported to a country with no extradition treaty with the US.
If I review a book it may be because the author or publisher sent me a review copy. Other wise I will quote a review of some one else. If I say a product looks interesting it is because it interests me. Sometimes I will link to books so you can educate yourself on a subject and so I can make some off the sale.
If some one employs me I will probably say good things about them as long as the money keeps coming. Or I may say nothing. To keep out of trouble with their lawyers.
That covers most of what I can think of. I'm getting old and sometimes I don't think of everything.
And if you have read this far please Buy Something From Amazon. I can use the money - well actually I will use the proceeds to buy something from Amazon. I get a better deal that way.
