How to get electricity for a portable house?

Like an RV…but it’s a tiny (120 sf) portable house built on a trailer. I’d love to use solar panels, but it’s looking WAY too expensive.
I don’t really cook, and mainly eat fruits and nuts… so I don’t really need to use a fridge. I’ll have a burner and microwave just in case, but won’t use it too much. I’d have a compost toilet.
I’d be using gas to heat.
The only thing I’d REALLY need electricity for it is to power my 24″ iMac and macbook pro as well as hard drives. I’m basically just making a portable office.

I could occasionally get hook ups, but mostly I’ll be doing boondocking/dry camping…

what is the most portable air conditioning with minimal electricity needed for a camping trip?

I am planning a cross country (us) cycle/backpacking/camping trip for myself and my kids. I hope to set off in early June as soon as school is out. Two of them have autism (one of which is severely involved, the other high functioning) and the third will be two in april. So, i need something extremely lightweight, portable and able to run off nature as much as possible. this is not for a nightly basis but for extreme circumstances when the kids (and myself of course) will need some relief. this adventure will take us throughout the next year + through rugged and extreme conditions from time to time. We will also be cycling, myself and my 10yr-old son will be the only peddlers. My oldest is too severe (disabled) to assist and obviously the 2-yr-old can’t help much. so we have to minimize weight as much as possible but have enough supplies to keep us safe and healthy. I am contemplating a 600amp power pack to use for nightly computer logging, occasional heating, occasional cooling (undetermined unit so far), occasional movie watching (dvds on comp), and mp3 and track phone charging. This pack can be hooked to a solar pannel for charging during the days while we ride and the pack weighs about 30lbs (another small child), but it also includes am/fm radio, alarm clock, ac and dc outlets, some models even have air compressors. Obviously we will have the smabeginningpumps due to tire repairs and air matress needs but i thought for 30lbs this includes several items in one and can be charged with solar. it can also be charged with a cord when access to plug is available. The tent we’ve decided on is rather large (up to 8 peeps) for the 4 of us. We have quite the convoy of family chariot trikes and trailers assembled. I really want to have a cooling device for those exhausting days – which i’m sure we will have many of, especially in the beginning until our bodies adjust. No need to cool the entire tent but an area to create relief. Any advice on cooling and power units that meet these needs would be greatly appreciated.

How to select solar panel charger for laptop (basic electricity related questions)?

Hi,

I have ASUS UL30VT laptop. The text on the battery says 15V, 5600 mAh, 84Wh. The adapter (black box on the cord) is:
Output: 19 V DC, 3.42 A, 65W
Input100~240 V AC, 50/60 Hz universal

I went to ebay and found different solar panels but I am not sure which parameters I need to look for. For example this one

http://cgi.ebay.com/5W-18V-mono-solar-panel-car-12v-battery-laptop-charger-/120746170292

It has a number of specs. Will it work for my laptop? And if not, which parameters indicate that? If yes, how long will it approximately take to charge the battery?

Also I found several other ones

http://cgi.ebay.com/Portable-Solar-Power-Panel-Kit-40-W-Laptop-Batt-Charger-/170514447329

http://cgi.ebay.com/NEW-Solar-Panel-Battery-Charger-LAPTOP-19V-US-/390325758943

which are way more expensive than the first charger. Why is that? Is it because they seem to provide not only the charger but also the battery? Or is it because the panel is more powerful which leads to faster charge times? Will it work with my laptop?

Malawi’s solar micro-finance initiative builds business for women entrepreneurs

Jessica Buchleitner – Women News Network – WNN

(WNN) Kasungu, Malawi: in the small landlocked southeastern African nation of Malawi only 8% of its growing 15.263 million people are connected to the national power grid, a source of power that has become increasingly unreliable. For many women and their families this often means only one thing – complete darkness at night or limited light generated only by candles or kerosene lamps.

Being a woman in one of the poorest countries in the world carries with it many burdens. in addition to struggling to provide for one’s family, limited access to the basic infrastructure, such as the use of electricity and water, can make necessary daily tasks for women much more limited and compromised.

Because of this, numerous women in Malawi are on the cutting edge with a strong desire to experiment using new technologies for energy.

“Electric power cuts are now a big problem in Malawi and they take place daily,” says Italian photographer Paolo Patruno who is working with a child blindness initiative at the Seva Foundation in Lilongwe. “The problem is getting worse because of the lack of diesel fuel for generators,” he continues.

Electricity in Malawi simply cannot be depended upon, and clearly these energy problems require a modern and innovative approach. this is why the United Kingdom based MicroLoan Foundation chose to launch its pilot program in Malawi – to provide economic opportunities to women using solar initiatives.

Off the Grid

The state owned power company, Electricity Supply Corporation of Malawi, LTD (ESCOM)  is the sole supplier in Malawi, a country with an estimated population, according to the World Bank, of 15.263 million people.

Nearly 95% of Malawi’s electricity supply is provided by hydropower from a cascading group of interconnected hydroelectric power plants located on the middle part of the Shire River, which flows through the Mwabvi Wildlife reserve in the south, and a mini-hydro in the northern region on the Wovwe River.

Current power generation is not meeting demand and to compensate, rolling blackouts are scheduled routinely. Rolling blackouts occur when electricity is stopped for periods of time over a geographic region.  They are usually in response to a situation where the demand for electricity exceeds the power supply capability of the network.

Much of the region is susceptible to extended periods of drought which can greatly limit hydro-power use, especially when water levels drop on the Shire River.

Rolling blackouts are often normal daily events in many developing countries such as Malawi, where electricity generation is under funded and local infrastructure is poorly managed.

Dangers of darkness

For a woman in Malawi, sewing and other activities by candlelight or dangerous kerosene lamps is the common reality after daylight hours. the instruments used for lighting not only offers poor light but are also known to be the cause of a host of health problems in women and children.

“Kerosene and candle light produce toxic smoke, inferior luminescence and present burning risk. Improved lighting is critical to reducing toxins, fire danger and eye strain,” said the World Bank in 2008.

Kerosene is a highly flammable dangerous fossil fuel that emits vapors. if kerosene is accidentally ingested, the vapors can cause coughing, dizziness, headaches, sore throat, unconsciousness and respiratory problems.

In Malawi, as in many other African nations, Kerosene lamps are huge contributors to respiratory problems, particularly among children. They are also the cause of extensive burns and even fatalities if accidentally knocked over or if the fuel is handled incorrectly.

“the kerosene lamp is a danger to Africa. It is a killer. every time you light a lamp, you get carbon-monoxide, and when you inhale it, it goes into your blood system and kills,” said Vice President of Uganda, Professor Gilbert Bukenya, a strong advocate for solar power, to ministers and diplomats at the Kampala Serena Hotel (Uganda) in September 2009.

Enter Solar

In and around Malawi’s rural area of Kasungu, a London based charity MicroLoan Foundation, has introduced a modern alternative of solar power sales as a business model for women entrepreneurs in the region. Providing business training and small loans to entrepreneurial women to help them work their way out of poverty, the foundation helps women develop business ideas that are then appraised as training is provided on topics such as book keeping and cash flow.

One of the MicroLoan Foundation’s new 2011 initiatives in Africa has been its solar enterprise work which is being piloted in Malawi. With alternative energy in demand in the region the program is progressing impressively.

Products such as a small 1.5w solar panel, an LED light, a mobile phone battery charger and battery pack which stores the solar energy are part of the sales for women entrepreneurs.

These products are specifically designed for rural settings, and the women are being trained and mentored in areas such as marketing to and educating customers as to how the panel’s work; repairing broken products; charging mobile batteries and taking care of stock management.

“The solar business has been generating good profits for me,” says sixty-year-old Veronica who comes from Salima, a small rural township in central Malawi. “Demand has been really high and there does not appear to be too much competition, so it’s a great opportunity. I have been making a regular income from charging people’s mobile phones at the market,” she added.

“Being able to integrate the solar enterprise program into MicroLoan’s work in Malawi has been truly inspiring,” said Paolo Mele, MicroLoan’s Social Enterprise Manager.

Veronica runs a teashop that was failing to generate enough income to support her family before she began her solar business. “I had to move my tearoom because the rent was too expensive here,” she said. now Veronica is making extensive additional income by renting out fully charged LED lamps every evening and charging people’s mobile phones using solar powered batteries.

With only ten solar panels and equipment packs the equipment to set up a business will pay for itself entirely within 2.5 months. after this Veronica can use her inventory to generate pure profits as long as she can. in her spare time, Veronica also teaches local women how to cook. She does this predominantly on the weekends when she can bring her attention away from the teashop and her solar sales.

“I have ten solar panels and these charge LED lamps that people use in their houses in the evenings – I rent them by the day. I’ve had lots and lots of orders from people and the local school wants to buy my whole stock of solar panels then next time I get some more,” said Veronica.

MicroLoan lending process  

With the “feminization of poverty”, lending to women has become a common practice in the Microlending circuit, as 75% of microcredit recipients worldwide are women. the MicroLoan Foundation provides loans to groups that include 10-18 women.

Each group has its business ideas appraised and receives eight training sessions covering topics such as book keeping and cash flow. all group members are required to save money as a source of security. Each woman receives her loan as a check and opens an account at a designated bank.

Individuals in the group then establish small commercial ventures. Groups meet with a loan officer every two weeks to review their progress. Repayments against loans are made routinely by each group member. When business is booming, it is the responsibility of the loan officer to ensure things get back on track.

Loans typically last for four months. Each group member is eligible to receive up to four loans after which their business should be commercially viable. Loans are small – on average £67 ($105 USD) per individual and an interest of 20% is charged in keeping with the local economy. For individual’s desiring to develop a business further they may receive a bridging loan of £140-£350 ($219-$547 USD) or access a separate MicroVentures service.

The loaning program operates on a continual gifting cycle: when the women repay their microloans, the money is then given to another woman. this process repeats itself.

MicroLoan has now set up a total of nine women as solar entrepreneurs in and around the Kasungu area.  the women have been selected on the basis of their successful business backgrounds and their ability to sell new products.

“MicroLoan Foundation is passionate about the change that solar energy can bring to the lives of the poor. With a large client base of women, along with a light yet efficient commercial touch, we are uniquely placed to roll this out,” said  Peter Ryan, MicroLoan’s Founder and CEO.

The women generally attend a two and a half day training workshop in Kasungu where they learn how their panels work, how to repair faulty units, how to charge clients mobile batteries, how to find clients and how to keep accurate record of their sales.

“The impact it has brought to our clients, their families and their communities has been fantastic. There have been so many positive benefits including children now being able to study in the evening, women generating a new income and being able to travel much less to conduct their business by relying on a now fully charged mobile phone,” said Mele.

Microfinance success for women in the Africa region is still happening. Women entrepreneurs in Malawi have been receiving assistance from the MicroLoan Foundation for over a decade. With training in business concepts women can build sustainable businesses using ingenuity as they become more self-reliant and empowered to choose new careers reaching greater levels of public participation in their local regions. this short 2:55 min 2008 video has been produced by the MicroLoan Foundation UK.

Solar 'Power Panel' provides solution for 500 million who have cell phones but lack electricity

Denver, CO (PRWEB) July 21, 2011

the exponential growth of cell phone use in emerging markets has been well-documented.

What’s less known is that 500 million of the world’s cell phone owners have no access to electricity, therefore no way to reliably, affordably charge their phones, according to the GSM.

The new, low-cost P101 and P102 solar Power Panels from Nokero International Ltd. seek to change that.

“We’ve heard stories of villagers traveling by foot and by boat, sometimes for days, to reach a place where they can charge their phones,” said Nokero founder Steve Katsaros. “In other places, people pay exorbitant prices to have their phones charged by vendors who use diesel generators and car batteries.”

Villagers in off-grid areas pay local vendors about US $2-$5 per kilowatt hour to charge a phone, according to the Carbon War Room. That’s compared to 10-20 cents per kWh in the average US household. the recharging stations use fossil-fuel generators to create power, polluting the air and creating unnecessary expense for people who only make dollars a day.

Sunshine provides more than enough power to charge these devices, but until recently there was not a solar product that was powerful enough – yet affordable enough, to be a viable alternative to fossil-fuel methods of charging.

A solar solution Nokero International’s high-tech solar power stations are specifically designed to charge cell phones and other small devices while remaining affordable to users who live in off-grid, often impoverished regions of the world.

To do this, Nokero streamlined the Power Panel design to increase its electrical power while maintaining low cost. its 1-watt version (the P101) can charge a typical cell phone in three hours. the 2-watt version (the P102) can charge a typical cell phone in 1.5 hours.

The panels have no battery – which removes much of a solar panel’s cost. They are made of high-temperature ABS plastics and high-grade, super efficient solar panels that last for 5-10 years if well cared for. the pocket-sized Power Panels are USB compatible and come with phone adapters. While they don’t charge smartphones, they DO charge the kind of phone used by the 500 million people worldwide who have cell phones but live without electricity (i.e. Nokia, Samsung, Sony etc.).

Improving lives and reducing poverty Empowering the world’s poor to charge their cell phones has beneficial economic repercussions. the cost of the original purchase of a cell phone charger can pay for itself in a matter of months, and afterward it saves the user from paying exorbitant re-charging costs.

USAID leaders have stated that food security is the number one priority, and research in Ghana and elsewhere shows that cell phone use can significantly improve farming practices and education.

Using solar power to charge cell phones in off-grid, impoverished regions can:

  •     Improve health by removing fossil fuel pollutants from the air
  •     Increase farm and food production
  •     Reduce family living expenses
  •     Provide small and micro-business opportunities for local vendors

An economic opportunity Estimates place the total market opportunity for solar cell phone chargers upwards of US $10 billion. the critical component is affordability – that’s why Nokero’s Power Panel bulk pricing is ultra-competitive.

The Power Panels are available online at nokero.com for $29 and $49, however these “sample-only” prices are well above the target MSRP for the product as it goes to market.

Nokero is working with NGOs, governments, and commercial distributors around the globe to help bring this game-changing new technology to market.

Accredited journalists can contact Nokero to receive a review sample.

Pan Charger boils your iPhone battery back to life – SlashGear

Japanese firm TES NewEnergy has launched a bizarre new way to charge your cellphone and other gadgets: using a pan of boiling water. the idea behind the Pan Charger was prompted when CEO Kazuhiro Fujita saw footage of earthquake victims huddled around small fires, and wondered whether integrating a heat-powered charger element to a regular saucepan would be a good idea.

“When I saw the TV footage of the quake victims making a fire to keep themselves warm, I came up with the idea of helping them to charge their mobile phones at the same time … unlike a solar power generator, our pot can be used regardless of time of day and weather while its small size allows people to easily carry it in a bag in case of evacuation” Kazuhiro Fujita, CEO, TES NewEnergy

Outwardly looking like any regular pot, the Pan Charger actually has a base plate covered in strips of ceramic thermoelectric material: the temperature differentials between the fire underneath and the 100-degree C water inside allow that material to create electricity, which is pumped out via a regular USB connection. anything that can operate on roughly 2W/400mA can recharge; Fujita reckons an iPhone would take around three to five hours to fully rejuice.

TES NewEnergy is offering the Pan Charger in Japan this month, priced at 24,150 yen ($300), but the company also plans to launch it in developing countries where stable power sources can be tough to find. “There are many places around the world that lack the electric power supply for charging mobile phones” Fujita suggests.

As the British well know, the best course of action in an emergency is to boil some water and make a nice cup of tea. Now, you can charge your smartphone and radio at the same time.
