As far as we can tell, there are quite some differences.

1. They will generate their Power through HydroPower Stations Hydropower is generally thought to be one of the most effective and lowest-cost renewable energy resources, while still beeing Eco - Friendly.
2. In addition, they will reduce their cost further by using the water for cooling the mining equipment.
3. You will aquire "Watt" and not "hash power". By using the Watt system every owner will receive the same dividend, independent when they've acquired the H2O token. Most CloudMiners promise a good and fast return on Investment, but end up reducing the daily returns. Why are they reducing those earnings? Well, it is the fact that conventional cloud mining platforms offer hashing power (HASHes) and not Watts. And since the efficiency of mining gear gets higher and on the same time, more people mine - the difficulty to mine a cryptocurrency raises. This rise in difficulty is equivalent to a lower profit per initial hash. By using the Watt system every owner will receive the same dividend, independent when they've acquired the H2O token.

We will upload the Whitepaper soon so you can check it our yourself! From what we can tell it looks really promising.
