The Sap Tap

There's more than one way to harvest energy from the sun. Trees have been collecting sunlight long before mankind first reflected it onto Solar Boilers! The Sap Tap extracts a thick and foul-tasting sap from trees. It is quite unpalatable, but the Caliometric Burner, having no tongue, won't notice. Small trees do not produce sufficient sap to be worthwhile; large custom trees produce the best output.
The sap tap must be placed underneath a log.
A good sap-producing tree will have hundreds of logs, and many more leaves; the Leaf Bomb may be useful here.
Placing multiple sap taps nearby might anger the trees, so as a safety precaution this is not allowed.
Sap can be converted into charge by feeding it to a Caliometric Burner adjacent to Boiler with a Whirligig and Charge Generator above.
