Next Big Future reports:

Liquid Piston gets more DARPA funding for 30KW engine 30 times smaller than todays engines

DARPA has awarded LiquidPiston an additional $2.5 million to continue development of its 30kW X4 rotary diesel engine prototype, bringing DARPA's total funding of the engine technology to $6 million.

When development of the fully packaged engine is complete, the 30kW X4 engine is expected to weigh just 30lbs and fit into a 10" box, while achieving 45% brake thermal efficiency – approximately an order of magnitude smaller and lighter than traditional piston diesel engines, and also 30% more efficient. The efficient, lightweight, and powerful rotary Diesel/JP-8 X4 engine offers a disruptive power solution for direct as well as hybrid electric propulsion and power generation.

Seems we get a story about a wonderous alt-energy breakthrough every week that never pans out, can the humble Diesel engine be reinvented to become the "next big thing?"

    Electricity is better in almost every way.

    Except for that storage thing... and, while you can transmit it "conveniently" on metal wires, wires aren't as efficient as tankers either. Then there's the whole "deadly if you touch it" thing.
