Introduction

Today, experience of the use of combustion motors to produce electricity from biogas is extensive; this can be regarded as a proven standard technology. Over 4,000 biogas plants with internal combustion motors are in operation in Germany. - [1]
1 cu m of biogas yields 1.7kWh of electricity (1.7kWhel)
Many new studies come to the conclusion that biogas power plants are not commercially viable without subsidies or guaranteed high prices (~0,20US$) for the produced outputs. In Germany and other industrialised countries, only guaranteed feed-in tariffs have led to a breakthrough. Almost all well-known biogas power plants in developing countries depend on financial support from a third international party. -[2]

Simple agricultural plant could cost as low as $3,500 per electrical kW installed - [3]
$660 per cow installed cost - 2 kWhr, or $7900 per continuous kW - http://www.uwex.edu/uwmril/pdf/RuralEnergyIssues/renewable/Biogas_Economics_Mehta.pdf
- Also shows 0.2kW/cow continuous production
