Evolving our Ideas to Build Something That Matters

When Jeffrey Brian “JB” Straubel built his first electric car in 2000, a modified 1984 Porsche 944, powered by two beefy DC motors, he did it mostly for fun and out of his own curiosity for power electronics. At that time, “EV” was already a hype among tinkerers and makers, but Straubel certainly pushed the concept to the limit. He designed his own charger, motor controller, and cooling system, capable of an estimated 288 kW (368 hp) peak power output. 20 lead-acid batteries were connected in series to power the 240 V drive train. With a 30-40 mile range the build was not only road capable but also set a world record for EV drag racing.

The “Electric Porsche 944” – by JB Straubel

The project was never meant to change the world, but with Tesla Motors, which Straubel co-founded only a few years later, the old Porsche 944 may have mattered way more than originally intended. The explosive growth between 2000 and 2010 in the laptop computer market has brought forth performance and affordable energy storage technology and made it available to other applications, such as traction batteries. However, why did energy storage have to take the detour through a bazillion laptop computers until it arrived at electro mobility?

 

You certainly won’t find that grail of engineering by just trying hard. Rather than feverishly hunting down the next big thing or that fix for the world’s big problems, we

Aero 2016: drones, aircraft parachutes and paragliding in a wheelchair

The Aero 2016 show in the German city of Friedrichshafen on the shores of Lake Constance was a success according to organisers.

Some 30,000 visitors attended the event, Europe’s largest and most important general aviation trade show, where more than 600 companies from 35 different countries displayed their latest products, from ultralights and gliders to business jets, helicopters and electric aircraft.

Whole aircraft parachute recovery systems, in other words parachutes that don’t just protect a single passenger but the entire plane, are a growing trend.

On display at Friedrichshafen was the single-jet Vision SF50 from Cirrus Aircraft, a brand new business jet. Once it receives operating approval later this year, it will be the world’s first business jet to be delivered with a parachute rescue system standard.

“The parachute that is on this airplane is call CAPS – the Cirrus Airframe Parachute System. We’ve had a parachute on every airplane we’ve ever made – that’s 6.300 planes. If the pilot is in an emergency, when all other things have failed, anyone in the airplane can pull a handle and the entire airplane will come down under a parachute,” explained Todd Simmons, Customer Experience President at Cirrus Aircraft.

Drones were also very popular at the Friedrichshafen show. With its racing drones, the exhibition’s indoor flight hall was aimed at seducing the younger, Playstation generation and electronics enthusiasts. Users wear glasses that provide them with a video image taken from the drone, giving them a pilot’s perspective.
