A Stirling engine is an EXTERNAL combustion engine. It has nothing to do with Gas. It operates on the principal of temperature differences. There’s plenty of data out there to help you understand how a Stirling Engine operates on principal.
The rationale behind the Inspirit Charger is that there are 20million domestic gas boilers in the uk that burn gas to a level of efficiency, but there is always WASTE HEAT from the exhaust of the boiler. The charger was developed with this in mind. BUT.....there are so many other applications of waste heat that can be identified, exploited, and manipulated in order to meet our climate change targets. Think of the British cycling mantra of Marginal Gains - there is no single technology or action that is going to help us achieve these targets, but a combination of complimentary and co-operative technologies and actions which will work alongside each other to achieve a combined increased reduction in carbon emissions. For example.....any situation where there is waste heat is an opportunity for the deployment of the inspirit stirling engine.....(not the gas boiler, but the engine that sits in the waste heat stream); these include any application where there is an INTERNAL COMBUSTION engine - how hot does your own car engine get, for example? Applying this thought to the marine sector, Ships carry huge amounts of diesel to power their engines, but still need electricity to power ancillary systems such as lighting, motors etc. Plug this into the Cruise line industry and you really start to see the opportunity. Most ships have engines for propulsion and engines for ancillary power. Each of these use generators which drag on the performance of the engine. The Stirling engine sits in the waste stream and does not drag on performance as it is taking advantage of a by-product. Whilst the performance of the Stirling engine is nothing like those of electric generators directly driven by Internal Combustion engines, it’s potential cannot be ignored in a “marginal gains” approach to energy conservation.
Think of a truck that pounds the motorway using diesel, but will soon not be allowed into city centres using the Diesel engine. It will need to switch to electricity. Having spent time charging through the waste heat, along with its alternator, the truck will have achieved improved efficiency at no additional carbon cost, through the addition of a Stirling engine into the waste heat stream...
The opportunity is waste heat. Not the fuel.
