Hybrid Vespas?

Aren't Vespas already fuel-efficient? That was my understanding, anyway. Well, the maker of the Vespa has introduced not-one-but-two hybrid Vespas that use less gas. Both use the LX 50 as a platform. The cool thing is that you can plug them into a socket. In theory, you could use them at your office as a power source to keep your precious air conditioner running while you work, even if California is doing one of its planned, rolling blackouts. Well, at least in theory. You would need a fleet of them to power up an entire office.
