Dave finally puts an end to the idea of Solar Roadways.
We have the test results of the world's biggest solar roadways project, the 1km long 336kW Colas Wattway project in Tourouvre France.

Solidworks jack the prices up in different countries and force local dealers to sell at higher local prices, just because they are dicks.
I love how the Dassault Systèmes logo looks like BS!
