Air travel today is 70% more energy efficient than it was in the 60s. Not that the left is impressed. Coal and oil allow people to heat their homes and drive to work. Solar power has a long way to go before it can catch up with efficiency and cost. Despite that, the left wants to put coal workers out of work. And they support rising gas prices. They don't seem to care that it will be unaffordable for people to heat their homes and drive to work. The poor will be hit hardest. Technology improves things each year, but we don't yet have a reliable source of renewable energy. Until we do, we can't start banning coal and other sources. Does the left prefer that people freeze while waiting for a substitute for coal and oil?
"The Solar Impulse 2 is an airplane powered by solar panels and uses batteries at night. In promotion of weaning the world off natural resources like oil (a dubious goal), the designers and pilots want to fly around the world using no conventional fuel.
While the journey itself is an impressive accomplishment, one can’t help but appreciate the abundance, affordability and reliability of oil. Brad Plumer of Vox compares the solar-powered technology with a traditional plane:
The Solar Impulse 2 features 17,000 solar cells crammed onto its jumbo jet–size wings, along with four lithium-polymer batteries to store electricity for nighttime. Yet that’s still only enough power to carry 2 tons of weight, including a single passenger, at a top speed of just 43 miles per hour.
By contrast, a Boeing 747-400 running on jet fuel can transport some 400 people at a time, at top speeds of 570 miles per hour. Unless we see some truly shocking advances in module efficiency, it’ll be impossible to cram enough solar panels onto a 747’s wings to lift that much weight—some 370 tons in all.
Nor is it enough to load up on batteries charged by solar on the ground, since that would add even more weight to the plane, vastly increasing the energy needed for takeoff. A gallon of jet fuel packs about 15 to 30 times as much energy as a lithium-ion battery of similar weight."
