Until all-electric cars are able to improve significantly in performance, you may need another, more practical option in the meantime. That’s where hybrid vehicles come into play. Examples such as the Honda Insight and the Toyota Prius are popular as eco-friendly alternatives to the traditional car that need less fuel, but are still reliable and perform decently.
A hybrid vehicle has a gasoline engine, as well as an electric motor and batteries for storing power. By combining the two kinds, drivers get the best of both worlds. For instance, engines running on gas are inefficient at low speeds, so the electric motor can take over at those times, whereas the gas engine can be there when you need more power. Remember to balance the better gas mileage against the higher initial cost of the vehicle.
Seed banks literally 'bank' seeds for our future. But a new study found not all seeds can be properly stored. HowStuffWorks looks at what this means.
