Cyclone is a company to
Cyclone is a company to watch. They've tried their scalable turbine in everything from race cars (their first project, I believe, was a Ferrari-like kit car using their engine) to big rigs to Humvees. Didn't they try one in a helicopter too? Can't recall if that a was a Cyclone or not.
Their turbines are especially well suited for power generation since they run at a given RPM with optimum fuel use and can run on just about anything combustible, from bio- to alt- to regular fuels.
In trucking, for instance, the use of an APU to replace engine idle time during driver down time saves a huge amount of fuel. The typical 6-cyl diesel engine in a rig (usually roughly 425-500 horsepower) uses about a gallon of diesel fuel per hour to idle. A diesel APU (usually 2 cylinder) uses about that in 12 hours. A cyclone of equivalent size would use a gallon in 30 hours. Then think about the refrigeration units on a cold trailer. Then think about an electric truck powered not by batteries, but by a right-sized cyclone instead. That would make OTR trucking with electric realistic and would make drivers happier since they could carry the same amount of fuel and go much, much further (probably 3x, as a guess). While reducing the weight of the truck to boot (less empty vehicle weight = more freight weight possible = better efficiency and more money per load).
These things have all kinds of potential.
