Personally I've been using FastSpring and 0 problems so far.
However they only work with apps, not webapps and such.
PayPal, PayMill, Braintree etc are all 3rd party payment
processors. So I don't quite understand your distinction.
I believe FastSpring may mean you avoid having to get a
merchant account directly so perhaps that's the
difference you see?
The biggest objection I've heard is the 9% flat rate they
take vs 3% and 30 cents per transaction that you'd roughly
see from a payment processor.
Previous launch attempt last saturday was in day light.
Yeah, but isn't it that the premise of the article is that you would combine energy from various multiple sources like, I don't know, 10-30 per house? Water flowing in pipes, generated heat, gathered kinetic energy?
It would be interesting to see some calculations how much could be gained that way.
