Hydrogen Fuel Cell Powered Aircraft + Greenest Cars

Boeing have successfully tested a manned hydrogen fuel cell powered plane in Spain this week.

The plane uses the fuel cells to power an electric motor and was flown to over 3000ft.

Lets hope this time around that hydrogen powered flight is a little safer...

From the same website I also spotted this nice little chart of the greenest cars of 2007:

Make and Model	Specifications¹	Fuel Econ. City	Fuel Econ. Highway	Green Score
Honda Civic GX	1.8L 4, auto [CNG]2	28	39	57
Toyota Prius	1.5L 4, auto CVT	60	51	55
Honda Civic Hybrid	1.3L 4, auto CVT	49	51	53

Toyota Corolla	1.8L 4, manual	32	41	46
Toyota Camry Hybrid	2.4L 4, auto CVT	40	38	46
Honda Fit	1.5L 4, manual	33	38	45

Hyundai Elantra	2.0L 4, auto	28	36	45
Honda Civic	1.8L 4, auto	30	40	44

And just for balance they also included the least green cars. Note the impressive feat from Mercedes who have made a 3.0l diesel engine less green than a 6.5l Lambo!
