A cheap high efficiency automobile transmission was demonstrated by Artemis with their hydraulic hybrid system. Even though the project was funded partially by UK funds from the Carbon Trust, the UK government is allowing this very efficient and low cost technology developed at government cost to not be used. Its efficient use should be mandated which would eliminate the need to mandate biofuels or to highly fund additional efforts. Artemis demonstrated the low cost and simplicity of hydraulic hybrids verses electric vehicles. They also demonstrated that a vehicle could be retrofitted. Others, such as NOAX, have also demonstrated efficient hydraulic hybrid technology. The hydraulic hybrid technology allows the use of many of the characteristics of high horsepower multi-piston engines without their cost and their inefficiencies where 15 kW is enough power for most ordinary travel even on motorways.

NOAX demonstrated a system even without an engine crankshaft. Pescara had another such system in the long forgotten past. Also to be mentioned is the very fuel efficient Kitson-Still diesel steam hybrid locomotive of the 1930s. The UK would be still using them if the North Sea fields had been in operation then. China should use them now since they still understand and use steam locomotives. Roger Waller of DLM could propose their use as well since he burns diesel or its equivalent in his retrofits and new construction, or he could incorporate Bladen jet engines as his burners. Porta's boiler water treatment gives steam boilers infinite life and is well understood and supported by his former co-workers. ..HG..
