A short excerpt from HV_Solar_DC_DC-Main.C  about the included libraries …

/----------------------------------------------------------------------------------
//  FILE:           Solar_DC_DC-Main.C
//
//  Description:    Solar MPPT DC-DC Stage
//                  The file drives duty on PWM1A and PWM2A for DC-DC boost stage on the HV Solar
//                  MPPT board. It also generates 50% duty with dead-band on PWM3A & PWM3B for
//                  the LLC stage on the same board.
//                  C28x ISR is triggered by the PWM 1 interrupt
//
//  Version:        1.0
//
//  Target:         TMS320F2803x(PiccoloB),

Micro Hydro Power

LV 1500 is a very small and efficient hydro power generator (max. power 1500W) made by Hydro Induction Power, a company based in Redway, CA  http://www.homehydro.com/.

The LV1500 re are 12V / 24V / 48V models build around a stainless steel Turgo runner, a brushless alternator and a rectifier.

Impressive is the that it works with 60 to 600 feet Head range and 5 to 100gpm Flow range.

For a greater energy need ( max. 4KW) they offer also  another product range here: http://hipowerhydro.com/


Passivhaus Institut – Passive House Institute of Germany

The Passive House Institute of Germany develops solutions for a higher grade of enegy efficiency in housing business.

The Passive House is a building standard that is truly energy efficient, comfortable and affordable at the same time.

The firstpilot project ( Kranichstein Passive House, Darmstadt, Germany, 1990) was Europe’s first inhabited multi-family house to achieve a documented heating energy consumption of below 12 kWh/(m²a), a consumption level confirmed through years of detailed monitoring.
