Energy “miracle” to go commercial

A New Zealand company that has developed an energy “miracle” to solve the world’s climate change problems is seeking investors to commercialise the product.

Christchurch-based IndraNet Technologies (IndraNet) is seeking six million dollars from investors to commercialise its revolutionary nGen Systems that will see businesses and individuals reach 100 percent solar sustainability at costs lower than current electricity prices without government subsidies, carbon taxes or tradable carbon credits.

nGen Systems aim to deliver on their premises the energy streams that customers require, including electricity, process heat, hot water, air conditioning, chilling, freezing, recycling waste heat, and grey water, with energy storage as an option where required. nGen Systems are intended to be deployed stand-alone or integrated to power grids to form highly distributed Intelligent Power Networks in the longer run.

“We are confident to deliver Sustainable Energy Services, based on our nGen Systems that will be competitive with fossil fuel based legacy energy services and at costs that will be a lot lower than electricity generated with other renewable energy technologies.” says Mr Fitts.

“Applications include industrial site, commercial centres, hospitals, schools, "green" sustainable buildings, residential homes, and eventually transport (by retrofitting compact nGen Systems to existing vehicles),” says Mr Fitts.

It sounds like they're using stirling engines with solar parabolic dishes and also possibly for the refrigeration, and re-using the waste heat in some form of combined heat and power scenario. There's energy storage as well (molten salt?), but I guess they couldn't use the stoerd energy in the stirling as the temperature differential may not be high enough (they could use another technology to use the stored energy, I guess). It's hardly a miracle, as it's been done before. But it is definitely a promising technology.

Thanks Davep. Here's more from their website:

The system itself comprises a front end compressor, a Burner Heater, a compressed air (or other gas expansion device and rear-end power generator. The front-end compressor, expansion device and rear-end power generator are coupled together or mounted on the same crankshaft.

The expansion device powers the front-end compressor. The compressor takes air and produces a small flow of compressed air. This compressed air is heated in the burner-heater. When a gas is heated at constant pressure it expands.

The flow of compressed air suitably heated expands 3 to 5 times through the burner-heater.
This expanded flow is then injected in the expansion device to power it.
