SMART ENERGY HARVESTING - BLUEFISH ZEV
One way of harvesting energy from the sun is with this giant magnifying glass from inventor Andre Broessel. It is so efficient, that even light from the moon is concentrated usefully. For our purposes, the system is far too bulky and so not smart enough, but it is an interesting architectural innovation - sort of like a Fresnel lens in reverse.
Linear Technology Corporation, a member of the S&P 500, has been designing, manufacturing and marketing a broad line of high performance analog integrated circuits for major companies worldwide for three decades. The Company's products provide an essential bridge between our analog world and the digital electronics in communications, networking, industrial, automotive, computer, medical, instrumentation, consumer, and military and aerospace systems. Linear Technology produces power management, data conversion, signal conditioning, RF and interface ICs, and µModule® subsystems.
Linear Technology Corp.
Energy Micro develops, markets and sells the world's most energy friendly microcontrollers, based on the industry leading ARM® Cortex(TM)-M3 32-bit architecture. The company was founded in 2007 by experienced semiconductor professionals with previous expertise from Chipcon, Texas Instruments, Atmel and Nordic Semiconductor. Energy Micro is backed by leading Nordic investors Northzone Ventures and Investinor.
Energy Micro provides the largest portfolio of energy friendly 32-bit microcontrollers and radio transceivers for ultra low power applications. The EFM32 Gecko microcontrollers include the energy efficient ARM Cortex-M4 with Floating Point Unit (FPU), Cortex-M3 and Cortex-M0+ processors, and the EFR4D Draco radios will also include Cortex-M3 for superior performance.

LORD MICROSTRAIN SENSING SYSTEMS
Energy Harvesters are materials and devices that allow ambient energy sources
to be converted into usable electrical power. There are several forms of ambient energy sources which generate power that can be captured and stored
for use in powering wireless sensor networks.
Electrodynamic generators and piezoelectric materials enable vibration to be
converted to electrical energy. Electrodynamic generators are coils and magnets in motion, producing an alternating current that is converted to
power. Piezoelectric materials are applied to vibrating structures and the
resulting stress or strain on the material will result in an output of alternating current which is converted to power. The MicroStrain EH-Link is
able to be powered by both electrodynamic generators and piezoelectric materials.
MICROSTRAIN ENERGY HARVESTING WIRELESS NODE
The EH-Link™ wireless node is a self powered sensor, harvesting energy from ambient energy sources. EH-Link™ is compatible with a wide range of generator types, including piezoelectric, electrodynamic generators, and thermoelectric generators.
Energy harvesting is all about conversion, storage and load leveling. EFM32 "Gecko (Gekko)" is a 32bit mixed-signal microcontroller. The proprietary technology EnergyMicro's "PRS (peripheral reflex system)" is a system to autonomously control peripheral modules inside the chip, without going through the processor. This feature makes it possible to reduce the power consumption, to achieve a long running at low capacity battery. The mode of operation and flexible ultra-low-power architecture is suitable for applications that require ultra-low power consumption.
A Bluefish ZCC depicting 40kW wind turbines [low operation mast height - left] [medium operational mast height - right]. This is a 50 ton vessel. The total energy harvesting capacity is around 176kW (235hp), giving an Energy Harvested to Displacement ratio (EH/D) of 3.52kW/ton (4.72hp/ton). Larger versions of this format could be the emission free cargo ships of the future.
The cost of diesel fuel to operate this ship continuously for a year is approximately: .29gals/hp x 117 x 24 x 365 = $297,226.80 (£183,393.99) In ten years that would be $2.97M (£1.83M). Fuel for thought!
