As a proud member of the American Solar Energy Society (for some three decades), I am thrilled to cheer for the Solar Impulse 2 arriving in Spain after a crossing the Atlantic. Earlier this year they completed a crossing of the Pacific, after transiting Asia and an unplanned halt for repairs in Hawaii.
In its stately circumnavigation of the Earth powered solely by solar energy, this aircraft has broken records and demonstrated that solar power is finally “flight ready”.
Only a few more weeks should see the round-the-world completed!
Frankly, this aircraft is far, far more interesting to me that all those quadcopters out there.
Like most solar enthusiasts, I envisioned such an aircraft from the moment I saw my first solar powered calculator. But flying is a merciless business governed by weight and power, ruggedness and reliability. It wasn’t really feasible then. But it is now!
I know that Solar Impulse 2 represents both great engineering and the ultimate confidence to get in the vehicle and fly across the Atlantic.
Well done, and Hurrah!
