Infrastructure Example

In this page we try to pull it all together and design an infrastructure for a small seastead using as much off the shelf technology as possible. We will use products from the West Marine catalog.

Introduction

The basic requirements are:

• The seastead stays put away from any port.
• We start with solar/diesel power -- no wind and no wave for now.
• Sewage is carted back to port for disposal.
• Everything is as turn key as possible. It just works.
• Preferably no propane. If propane is required, propane sniffers are a must.
• Safety. Everything just safely shuts down if there are problems.
• Rough costs only. No need to shop around yet.

What we want is:

• A kitchen with a refrigerator, a sink with hot and cold water, a stove and an oven.
• A bathroom with a toilet, hot/cold water sink, and hot/cold water shower.
• A living room with enough power to run an audio visual center and a computer with Wi-Fi. No need to specify the A/V or computer equipment.

The required equipment is listed below.

Power Management

The power system will be based on batteries. Both the solar and diesel generator can independently charge the batteries.

• Batteries (how many? how big?)
• 120 Watt Solar Panel (WM#:8909350 ~$1000)
• Sun follower?
• Diesel Generator (auto start? How big?)
• Power management electronics
• AC Inverter
