For instance, we can usually get 5kwhr to 10kwhr per gallon of gasoline in ICE.

However, they are more efficient than most internal combustion engines.[" "In contrast to internal combustion engines, Stirling engines have the potential to use renewable heat sources more easily, and to be quieter and more reliable with lower maintenance." https://en.wikipedia.org/wiki/Stirling_engine

I doubt that this thing could put out 15 W, maybe 1.5 W.

I doubt that this thing could put out 15 W, maybe 1.5 W.It does say Wattage of 150W. Nobody believes it of course.

Typical LED bulb input is 20W.That's a 3 W led in the photo. -- Cheers, Carlos.

The articles are scattered throughout the Philips Technical Review, so they take ages to find. If Philips' management hadn't been so bad and shut down their manufacturing and research, they would now be in a position to make a killing with all the expertise they built up. -- ~ Liz Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk
