Design of the Day: BMW Group Designworks USA solar carport

May 13, 2014 § 1 Comment

BMW-i-solar-carport-002No, not just a concept: this is actually up for sale (albeit at a price, no doubt; tba). BMW’s DesignworksUSA studio is presenting – to tie in with the launch of the i8 plug-in hybrid in Los Angeles – a solar panelled carport for EV charging. Its key points are bamboo struts (bamboo = quick-growing, sustainable raw material), carbon elements (strong, correlates with the carbonfibre of the i8 itself) and translucent glass-on-glass PV modules. The carport – which will be on offer in Europe as well – works in conjunction with BMW’s i Wallbox Pro control system, and surplus solar energy can be hived off for domestic use.

  • Further to Toyota’s trash-to-gas set-up (using waste methane from a nearby landfill site) at its plant in Georgetown, Kentucky, the company has now installed a stationary fuel cell at its sales HQ new Los Angeles (yes, another LA story today). This 1.1 MW cell is said to be the largest of its kind in the world, and will supply around half of the power needed by the six buildings on-site; it can be turned on and off quickly according to demand, has twice the energy-generating capacity of the solar array already in operation at the site, and generates power equivalent to that needed by 765 average American homes. The hydrogen is produced off-site by natural gas reformation (Toyota is offsetting the carbon byproducts of this by buying renewable biogas from landfill waste, it says). A 1,500-tonne saving in carbon dioxide emissions from the site is expected during peak summer operating hours.
  • Latest forecasts for electric motorcycles and electric scooters from Navigant Research: annual sales of the bigger e-bikes will grow to 1.4million in 2023, and the smaller scooters to 4.6million, the market expanding from 2015 as new products become available and their quality/abilities (range) improves. Growth will be in North America and Europe in particular, with an annual growth rate of over 30%. Speaking of which, Mahindra has opened its production plant in Troy, Michigan to make the GenZe e-scooter for the North American market (more here and here), and BMW has now launched its C evolution electric ‘maxi scooter’.
  • How do you process algae into biodiesel? With bi-functional nanoparticles, of course. New developments at the US DoE’s Ames Lab, reported here.
  • Drayson Technologies Ltd (new holding co encompassing the e-racing team) has set up a new division, Drayson Wireless, in partnership with Imperial College, London; aim is to commercialise its wireless induction charging tech. More here.
  • AlcoMix: sounds like a nasty night out on the town, but it’s the name for a high-octane syngas-derived fuel which can be drunk neat by petrol engines or blended with petrol as a better bet than ethanol. Reported in detail with journal refs/citations at Green Car Congress.
  • CNG: more costly to the environment than diesel for use in London buses, according to a lifecycle analysis study from Cambridge. Details, citations at Green Car Congress.
  • But a Proterra electric bus just did 700 miles in 24 hours in a record-breaking run designed to simulate real-life operation; its MPGe was claimed to be six times that of a diesel bus and seven times that of one running on CNG. More at Green Car Reports.
  •  Some presentations from the Mobilities and Design Workshop, Lancaster University, posted here. Some good points by Alison Hui on the intersections between travel behaviour, practices, and engagement with infrastructure.
  • A five-EV taxi fleet based in St Austell, Cornwall, has clocked up 150,000 miles in a year, reports Transport Evolved. C&C Taxis reckons it has saved £40,000 in fuel, its Leafs – soon to be joined by an e-NOV200 – cost around 2p a mile to operate, and that customers prefer the EVs as well. Nice story.
  • And an update/general thoughts on the progress towards e-mobility from the Civil Service/OLEV… Explains a bit about what the Office for Low Emissions Vehicles actually is, and what it’s trying to do.

§ One Response to Design of the Day: BMW Group Designworks USA solar carport

    Loads of interesting stuff, as ever, but the CNG story is a bit misleading. Even the summary at GCC says that they were comparing the baseline diesel fleet with a lean burn CNG engine – that’s old technology. Modern gas buses have stoichometric engines, which means they can use a three-way cat. At Euro V that makes them significantly cleaner than diesel, while at Euro VI they may or may not be cleaner (no data is available yet) but they’re certainly simpler.
