General Motors EV1 & the land speed record for electric vehicles

You may have heard of the General Motors EV1 – an electric car produced between 1996 & 1999. It was unique in a number of ways, including being the first GM vehicle designed purely as an electric car & also in bearing the General Motors brand,1 rather than that of one of its divisions (Chevrolet, Buick etc.)

Predecessor of the EV1 was the Impact concept car, first shown to the public in January 1990, by GM chairman Roger Smith, at the 1990 LA Auto Show. In 1994, a modified Impact set a land speed record of 183.822 mph (295.833 kph).2

Many sources, including Wikipedia describe it as, “a land speed record for production electric vehicles”. Apparently, “production”, refers to the 50 Impacts hand built for the, PrEView, programme – which saw cars lent out for one or two weeks at a time, to gain feedback from members of the public.1

Ultimate fate of the EV1 is recorded in the iconic 2006 documentary, “Who Killed the Electric Car?”

Where the land speed records for electric cars are now

On 28 July 2016, a land speed record for street legal EVs was set at 205.6 mph (330.9 kph) by a modified Corvette.



For vehicles unhampered by street legality concerns, Drayson Technology moved the record up to 219.1mph (352.6kph) in March 2014.



As of 22 September 2016, the outright record was set at 341.4 mph (549.3 kph) by Venturi – an offshoot of the organisation that runs the Formula E team.

Redflow claims to have a better solution for home electricity storage

Redflow has a home electricity storage solution using a flow cell with zinc-bromine electrolyte. Alternatives, such as the Tesla Power Wall, use lithium ion technology.

Claimed advantages of Redflow's flow cell include:

● tolerant of daily full cycle (100-0%) charge-discharge – don't try that with lead, nickel or lithium based batteries

● well suited to a heavy workload
● less loss of capacity through its lifetime than other chemistries
● doesn’t need active cooling
● sleep mode with zero self-discharge [sic]
● non-flammable electrolyte

SPUD – Spontaneous Pop-Up Display



SPUD in use
Credit: Arovia

Assembled, SPUD has a 24" screen with a 16:9 aspect ratio, at 1280 x 720 resolution, & weighs 2 pounds, that collapses, “just like a ruggedized umbrella”, to a 7.52 x 5.64 x 2.17 inch, package. Image is displayed by rear projection.



Two problems spring to mind:
1. in my experience, resolution is a problem with rear projected displays
2. creasing of the screen after repeated collapsing seems likely

Arovia, the creator, claims to have solved both of these problems.

SPUD is crowd funded through IndieGoGo

A 100% renewable electricity grid is not just possible, but essential



Credit: Conserve Energy Future

Scientists agree that the world is warming, & that human activity is substantially the cause.1 Cost, both in financial terms2,3 & impact on human well beings,3,4 is enormous.

Electricity generation is a substantial source of greenhouse gases. A 100% renewable grid is thus, essential. Good news is that such a grid is also feasible according to a paper recently released by the Alternative Technology Association (ATA).

Uber self driving car runs a red light (video)




Uber has been running a pilot programme of its autonomous vehicles in San Francisco. One of those vehicles was caught running a red light on a dash-cam. Check the sensor array on top of the vehicle.

Uber was quick to issue a statement attributing responsibility to the staff member in the driver's seat:

“This incident was due to human error. This is why we believe so much in making the roads safer by building self-driving Ubers. This vehicle was not part of the pilot & was not carrying customers. The driver involved has been suspended while we continue to investigate.”
