hyper efficient piston genset for recharging electric vehicles
R e g e n g e n
Regengen is the brand name for a range-extender for electric driven transport described above.
The one stroke engine was developed in 2001-4, patented 2003 and presented at Engine Expo 2005.
Unfortunately that was a time when EV rechargers were not taken very seriously by most people in the transport industry.
Without visionary people in positions of funding, then the chances of funding were slim, despite exhaustive attempts.
It is a matter of opinion, but many observers believe that batteries can never match the power density of fuel and therefore many electric transports will need a power source using liquid fuel, such as a turbine, fuel cell or ICE generator - depending on the journey, access to recharging facilities and flashing techniques. Turbines have low efficiency and fuel cells remain production-sceptic - which leaves the ICE as the most likely range extender.
The Regengen website moniker was purchased in 2006 to promote this concept specifically for general transports.
There are two main issues for a transport generator; firstly fuel efficiency, and secondly overall weight.
In both areas the regengen described above is outstanding. While the CLP engine itself is not as lightweight
as a turbine or wankel arrangement, superior fuel efficiency means lower fuel load and extended range.
The regengen specifically uses a compact linked piston engine coupled via a soft start clutch to a generator.
This clutch is likely to be viscous/hydrodynamic. There is only one specific downside of the CLP engine and that is a weaker crankshaft due to spatial constraints. However using a soft start - and soft end - clutch, negates any crankshaft worries.
The main difference versus the sister Flygenset concept is using cost realistic components unnecessary when not in aircraft.
From nano chargers for telephones and laptops, to mW generators the Regengen is a scaleable concept effective in most sizes.
