Thermo PV Midnight Sun Stove® by JX Crystals - generating heat and electricity from combustion energy

Proe Power Systems afterburning Ericsson Cycle Engine is perfect for combined heat and power applications. Much simpler and more efficient than Stirling engines. Exceeds diesel fuel economy without diesel exhaust pollution. Ideal for alternative fuels.

Liberty Hydrogen Home Generator - This quiet home electrical generator produces clean power from water and can be easily installed inside your home.

Menova Energy - The Power-Spar® is a revolutionary high efficiency solar concentrator that provides heat, hot water, and electrical power.

AffordablePower - Waste Oil Generator Burns 100% Waste Vegetable Oil, Motor Oil, or Hydraulic Fluid. If you use your generator 4 hours per day, you could save $480 per month in fuel costs.

Climate Energy - Micro-Combined Heat and Power, or Micro-CHP, is an approach to delivery of energy to homes that can dramatically lower overall energy use and reduce impacts on the environment. The fuel used to heat the home is used twice: first to generate electric power, and then heat the home.

Dawn Solar Building Integrated CHP applications produce heat and electricity from under a roof or wall surface. Cost of $.03-$.10 per kWh (thermal equivalent)

solarcentury - Disguised as conventional roof tiles, C21e solar electric tiles and C21t solar thermal tiles together form the CompleteSolar Roof, generating electricity and hot water.

STM Power [link broken as of at least 9/26/08] - We sell ultra low emissions, external combustion, combined heat and power generators using Stirling-cycle engines. The STM PowerUnit is a compact and environmentally friendly generator of electricity and hot water. STM PowerUnits have been designed to achieve 30% net electrical efficiency and 80% total system efficiency in a combined heat and power (CHP) mode.

EC Power - EC Power solutions consist of a co-generation unit powered by natural gas or diesel, a heat storage system and an advanced computer management package. The EC Power Combined Heat and Power solution can reduce energy bills by 40 - 60%, or increase efficiency by more than 100% - a considerable improvement.

Power-Spar® is a high efficiency solar concentrator that provides heat, hot water, and electrical power.

Vector CoGen - Electricity generation and hot water supply using natural gas for reduced carbon dioxide emissions. VectorCoGen LLC systems are so efficient, (up to 90% vs. 30% from the power company) that residents and light commercial users can use cogeneration to produce power and heat for their onsite needs at savings from 20% to 70%.

Ranotor - Small scale steam power below 1000 kW is well suited to combined heat and power (CHP) applications, offering fuel flexibility, low NOx emissions, low energy consumption and high power density. Ranotor expects to achieve 32% efficiency at part load, 3 times higher than a conventional ICE at part load, with 60-65% being used for heating and 5% heat losses.

Energy-only generation created from combustible energy sources

DEKA's Project Slingshot stirling electricity generator that works on cow dung alongside (seperate) a water purifier was invented by Dean Kamen in order to be used in the developing world.
