The stupidity that just won't die! Solar Cycleways and other snake oil!!
This stuff really does drive me up the wall!
The sheer scientific illiteracy of the media!
So a week or so ago, we had all these stories about how 'solar cycleways in the Netherlands had generated more energy than expected'.
Turns out it was still only 50 % of what would have been generated if those same solar panels had been put on the roof of a building. But hey 'solar cycleway generates half power of roof installation' really isn't as eyegrabbing a headline as 'solar cycleway generates more energy than expected'. Grrrrr
EEVblog did a pretty comprehensive analysis of this- recommended!

Then we had the buzzfeedblue team add another million or so hits to the 'hendo hoverboard', with their aspirations to levitate buildings in earthquakes.

The cost of the motors, and more importantly a power supply that can supply about 2 megaWatts of power during an earthquake is kinda a killer there!
Which brings me onto Cara Santa Maria, who while she has her moments.... telling a scientist that 'yeah, you just did your own calculations' is hardly a persuasive argument!
Thing is with 'aircarbon' is it really is mis-selling stuff. What they really are describing is plastic made from bio-generated methane. They are not talking about 'making it from the air'. Sure is an easy way to milk scientifically illiterate eco-warriors though!

And yeah Cara, thats the great thing about understand the subject you are covering, you dont have to understand the process if you are dealing with state functions. Thermodynamics is not dependant on the process!
Oh and yeah, as I said in at least one of my solar roadways videos.... arguably a plausible way of doing this is simply by putting a roof over the road with solar panels on... like the cycleway in S. Korea
