Nissan’s Electric Leaf Becomes a Van: The e-NV200

Posted: 27 May 2012 02:06 AM PDT

 
Nissan has been quite enthusiastic about its electric car, the Leaf — and with pretty good reason. It goes, it’s comfortable, and it’s cute to boot. The next step, clearly, is to take the tech that works so well in the Leaf, and turn it into a miniature cargo van — Nissan’s e-NV200 starts production next year.

Okay, Gas2 readers, it's rhetorical question time: Do you remember Nissan's electric van? The one where it looked like they chopped off the front end of the Leaf and stuck it onto a metal box? (Because that's more or less what they did.) It seems to be more or less done testing and actually slated…

Mission Africa — 3000 Miles in an Electric Car: or, Xavier Chevrin Is Manlier Than You

Posted: 27 May 2012 01:59 AM PDT

 
A depressingly high percentage of new car buyers don’t even want to hear about the potential benefits of an electric car. “It doesn’t go far enough per charge,” they complain, or “But where am I going to plug in it? My garage is full of stuff and there’s no plug on the street!” In a single fell swoop (okay, it’s a six-week trip) titled “Mission Africa,” Frenchman Xavier Chevrin is setting out to prove that it is possible to drive an all-electric vehicle 3,000 miles through Africa, on bumpy (or even non-existent) roads.

If a Frenchman can drive an electric vehicle 3,000 miles through Africa, you can certainly handle driving an EV the fifteen miles to work and back, plus around the city for shopping. Just driving through Africa is generally some sort of adventure; whether it's the relatively tame massive potholes…

Solar Power in a Suitcase for Medical Situations

Posted: 27 May 2012 01:58 AM PDT

 

Obstetrician Laura Stachel from Berkeley, CA was on a medical relief mission in Africa when she observed a C-section being performed at night,… by the light of a kerosene lantern. The lantern died during the operation, so the rest of the procedure had to be completed with a flashlight.

She was shocked by the lack of resources available for medical treatment during her visit, so when she returned home she set about trying to come up with solutions.

Her husband works in the solar industry, so he began to experiment with various combinations of solar panels and small lights to invent a portable solar kit that could be used for medical field trips in Africa. Solar power and a small battery system seemed to be the best choice, because villages in rural areas are off-grid but there is abundant sunshine during daylight hours for recharging batteries.  Also, small lights could be stored in the same suitcase kit for transportation and protection during trips.

Today, their suitcase solar kits are used in nearly 200 medical clinics in various locations across the planet. Initially, the kit was designed for use in obstetric situations, but now can be employed in any medical emergency or healthcare event.

Key components of the system are solar panels for generating 40 or 80 watts, LED lighting for medical tasks, chargers for batteries and cell phones, and a 12-amp-hour sealed lead acid battery. There are also outlets for 12V DC electronics. This system can also be expanded to accommodate 200 watts of solar panels and a 140-amp-hour sealed battery.

About 15,000 mothers each year are now provided emergency medical care 24 hours a day because of the solar suitcases. Reportedly, over 350,000 mothers die from pregnancy complications each year.

Additionally, these small portable lighting systems don’t generate air pollution by burning kerosene, and don’t have the same potential to start accidental fires.

HyperSolar Envisions Solar Powered Hydrogen “Farms”

Posted: 26 May 2012 04:21 PM PDT

Hypersolar envisions solar powered hydrogen production systemsLast year the solar company HyperSolar, Inc. filed a patent application for a solar powered system that creates renewable methane gas from water, which it has been testing out at California’s Salton Sea.  Just last week, the company announced that it has completed  a proof-of-concept prototype for a solar-powered hydrogen generator, so this looks like a good time to check in and see what they’re up to.

Everything you need to know about hydrogen

Hydrogen can be produced from plain water through a reaction touched off by electricity. However, it takes a significant amount of energy to split hydrogen atoms from water molecules. If the energy in question is a fossil fuel then hydrogen is a wash in terms of reducing greenhouse gas emissions.

An emerging solution is to develop hydrogen production systems that are integrated with solar power, essentially mimicking the natural process of photosynthesis.

One notable example of this approach is MIT researcher Daniel Nocera’s solar powered “artificial leaf,” which is based on a small solar module the size of a playing card.

Plastic bags, solar power and green hydrogen

Hypersolar’s system goes even farther down the size spectrum, using tiny particles consisting of a nanoscale solar device and a protective plastic coating.

The particles float in water, and the coating enables them to function in hostile environments including  sea water, wastewater or stormwater runoff. That gives the system a leg up on conventional hydrogen systems, which require purified water.

The reaction takes place at ambient temperatures, so it can take place in a low-cost glass vessel or even an ordinary plastic bag.

For the proof of concept prototype, Hypersolar used a baggie placed in wastewater from a pulp and paper mill.

A little help from hydrogen friends

Hypersolar recently partnered up with the UC-Santa Barbara College of Engineering to bring the technology closer to commercial development, with a focus on using municipal and industrial wastewater as feedstocks. Potentially, the system could be scaled up to form sprawling hydrogen “farms.”

When they’re ready for another announcement, we’ll be sure to check in again.

22.24 GW of PV-Solar Output in Germany — New Record!

Posted: 25 May 2012 09:30 AM PDT


Thursday, PV-Solar broke through the 20 GW barrier for the first time, but before I managed to write about that, it’s old news already. On Friday, output from PV-Solar climped up to a staggering 22,240 MW as Germany experiences a week of wonderful summer weather.

Thursday

To start, I will take a short look at Thursday’s record, which was historic to say the least. At about 12.45am, solar peaked at 20,097 MW. Throughout the day, it produced about 167 GWh of electricity.

That sure sounds like a lot, and it is a lot, especially considering that Germany consumes 1,200-1,400 GWh during a typical day in May.

So, 167 GWh, about 12% of the total electricity consumption, is coming from PV-Solar in a highly industrialized country. I don’t know about you, but that sure sounds like cool news.

I’ll write more on Friday’s and coming records later, but wanted to get this news out asap.
