Great idea: tidal, river, current generated hydro-power.

Hell, why not hook these things up with some windmills above water too!

Now how to avoid killing fish…

…and, comes in an amazing portable size!

…“Bourne’s militarized Backpack Power Plant-Type 2 (BPP-2) measures only 3 feet in length and weighs less than 25 pounds, approximately 10% lighter than the original BPP-1. Like its civilian predecessor it is self-contained with its own integrated power, control, cooling and sensor systems. The unit collapses into three major parts which slide into a large backpack. The BPP-2 produces up to 20% more power (600W) and can be set up singularly or in arrays of over 20 kW. The BPP-2, which operates silently with no heat or exhaust emissions, is 40% less visible during operation and can also be bottom mounted to be totally invisible.

The BackPack Power Plant - Type 1 (BPP-1) is a man-portable renewable energy generator only 3 feet in length and weighing less than 30 pounds. Each unit is self-contained with its own integrated power, control, cooling and sensor systems. The unit collapses into a backpack size module with the generator, hub and folded blades stored inside. The unit produces approximately 500 W/unit high quality continuous power depending on river current. The BackPack Power Plant can be set up singularly or in arrays of over 30 kW.”
