CAPE testing facility in Westfield, Ind., to test the structural integrity of REV’s standard ambulance module construction. A new modular body on a Type 3 Ford E-350 chassis was put to the (sled) test at the Center for Advanced Product Evaluation. The ambulance was engineered and built using the exact same methods as units built for REV customers.
(do mfg's do crash tests as bare cab chassis or with a simulated load on them?)

The new design converts direct sunlight to electricity with 44.5 percent efficiency, giving it the potential to become the most efficient solar cell in the world.
The approach is different from the solar panels one might commonly see on rooftops or in fields. The new device uses concentrator photovoltaic (CPV) panels that employ lenses to concentrate sunlight onto tiny, micro-scale solar cells. Because of their small size—less than one millimeter square—solar cells utilizing more sophisticated materials can be developed cost effectively.

This particular solar cell is very expensive, however researchers believe it was important to show the upper limit of what is possible in terms of efficiency. Despite the current costs of the materials involved, the technique used to create the cells shows much promise. Eventually a similar product may be brought to market, enabled by cost reductions from very high solar concentration levels and technology to recycle the expensive growth substrates.

For more than 70 years, solderless terminals have been used on everything— from automobiles and appliances to warships and commercial and military aircraft (Boeing hasn't soldered a crimp in over 40 years). Developed in the days leading up to WWII by the aircraft manufacturing industry, they are a tried-and-true system for making low-resistance, solder-free electrical connections.
