An Electric Car With 400 Miles Of Range ?

John Wayland (of White Zombie Datsun fame) is at it again...
Building a combo of the old (recalled) GM EV1 and Honda Insight, with better batteries.
John's expectation is he'll have a 400 mile range!

100,000 EVs -- more info

I mentioned in the 5/23 post that I had heard there were now over 100,000 EVs on the road. 
A little more detail:  That figure is 100,000 "plug-in vehicles" - this includes pure EVs (like Nissan Leaf) and ALSO plug-in hybrids of the various types (parallel operation like the Toyota Prius and serial operation like Chevy Volt)

Here is the story:

And here you can see the Plug-in vehicle "counter" (showing 102,662 at this moment!)

EV news -- bad, bad, and (maybe) good

Better Place – bad

Fisker – bad

Tesla – good.  Tesla talking yesterday about a cross-country charging network.  I think they have a good product with the “S” that many more would buy… IF they can get the price a little lower.

 

Better place:

Electric vehicles - EV

I'm hearing today (from a reliable source) that there have now been 100,000 EVs produced!

More as I get details.

Solar Energy: Man beats Nature!

Even working on seemingly unrelated projects, energy questions come up in the conversation. My son, Nathan, is working on his Eagle Project. It involves some sawing. One of the boys helping is using a hacksaw to cut some PVC pipe and asks, "Where does the energy come from to cut this pipe?"

 

Well, that's quite a question. The boys start spouting their knowledge. One says "from your muscles!" Well, sure, but... Another says "food!" Getting a little better, cellular respiration anyone?   I whisper to one of the dads about a series of energy conversions. He says, "Chemical energy."  I say, "the Sun."

 

Whoa. How did solar energy make it into this worksite conversation?  It seems to happen that way a lot.

 

Especially interesting about bringing up Solar energy is that my son’s project is the construction of raised garden boxes for the Temple Israel garden.  (These should make it easier for some of the older congregants to tend some of the vegetables.)  Of course, solar energy is what makes the plants grow.  How this happens is not a mystery to us, but how efficiently do plants use the sun’s energy?  – well THAT is a good question. 

 

Using the sun to make electricity is, of course, a great idea, and scientists have been working hard to improve the PhotoVoltaic cell to convert more of the solar energy into electrical energy.   Recently, best efforts have PV cell efficiency at about 27.6%.  (see this August 2011 IEEE Spectrum article:   http://spectrum.ieee.org/green-tech/solar/solar-cell-breaks-efficiency-record.)  Then there’s some decrease in efficiency once the cells are packaged into panels, and of course further loss as the electricity is converted to AC and ultimately delivered to a load. 

 

But what about plants?   You might think that they are much better, given that they are Nature’s own design for capturing the sun, and they’ve had billions of years to evolve and improve the process.   Well, it looks like Man has the lead on this one!  The USDA reported on some very interesting research in this article: http://www.ars.usda.gov/is/pr/2012/120112.htm.  Plants don’t make electricity (not YET, anyway), but rather convert the sun’s energy into chemical energy.   So agricultural scientists put the plant and PV solar conversion processes on a direct comparison (apples-to-apples), and found that plants have a year-round average conversion efficiency of 1%, while solar PV converts 10% on average.  Wow!  That surprised me.  It says we need to apply man’s expertise in crop science – focusing the science to improve efficiency could lead to improved crop yields – and that could be a great benefit to our growing population!

Saving energy (and money) can be easy

Personally, I think the water heater can be set lower than 120 degrees --- that's still pretty hot.  If you're worried it's not hot enough for the dishwasher, use the "high temperature wash" setting.  That way, you're only using very hot water (and extra energy) for washing dishes.

Electric Transportation - the old-fashioned way!

  Visiting the Pensacola Museum of Industry last weekend, (part of "Historic Pensacola Village") I spotted a relic from the days when EVs ruled the road.  It was the stalwart of public transportation.  It was an electrical innovation.  It was... of course... an Electric Trolley. 

  Sponsored and operated by the local electric utility, Gulf Power, (same Gulf Power as it is now), the trolley ran the streets of Pensacola using power from overhead electric lines.  Would you believe that in its peak year (1920), the 30 trolley cars in service carried 4 million passengers a year?!

  Perhaps this is something we will see make a comeback?  I'd think a power line infrastructure over the streets wouldn't be very popular today, but with improving battery technology, it would become a "wireless" trolley -- the new EV that rules the urban road. 

  Until then, this is a piece of nostalgia that makes the museum visit so enjoyable -- it gives us engineers something to think about, and the kids some to play around on -- they love playing with the seatbacks that flip so you can sit facing the front or the rear!
