How much energy does it take to lift a squirrel on a solar sail?

Well 1 snickers contains roughly 1.1 megajoules. Say the squirrel weighs roughly 250 grams - I've never had the compunction to capture and weigh one - which would mean it would take 2.45 joules of energy to lift it 1 meter against Earths gravity.

With the low end of human muscle efficiency in the conversion of energy into power. Ideally you'd be able to fire the little beastie ~63km off the energy of a snickers.
