Healthy food via solar cooker
Although good solar cookers have been available for two decades, they were out of reach because of distribution issues. Nowadays you can even order them on online. Food cooked in solar cooker taste better
Prices of crude oil are falling globally but in percentage terms nowhere close to the way prices of solar powered products and cells as well as reflecting surfaces used for solar energy purposes are falling too. Not just photo-voltaic and photo-thermal cells but even paint-on or paint-apply reflective surfaces, which can be used to generate energy with even the least amount of Sun regardless of ambient temperatures around.
For the last few weeks, we have been using a new generation solar cooker at home for cooking a variety of food items in Delhi's cold weather. The list of items we could not cook is mutton (gave up after five hours, but that is also because it became foggy) and rotis (we need to tweak the flour used so that it can "rise" like a "kulcha"). Everything else can and has been cooked. Even French toast.
For the rest, for a family of five, sometimes six people, we have been able to cook a variety of raw unpolished rice (100-120 minutes), polished rice (60-75 minutes), lentils (90-120 minutes) and vegetables (60-150 minutes, depending). Food ends up tasting better, and for those of us who recall what daal tasted before pressure cookers entered our homes, tastes fluffier too. 
Cooking by solar also requires less oil/ghee, as the process involves slow cooking at its best, and this in turn reduces the amount of oil wasted by simply being burnt away. There is no need to keep stirring also, as the heat is applied from all around and within.
The all-important "tadka" is applied previously or subsequently as per your taste. Solar "chaunkh" never tasted better, especially if done in a covered vessel left in the solar cooker for a few hours to heat up well.
Prices for a typical four-container/vessel type solar cooker now start from as low as Rs2,000 upwards and there is no "brand" value attached to them. Modern nano coating techniques enable even plastics and polymers to be coated, as also metals, which can be bent or curved to any shape wanted. The one we use looks like a medium sized suitcase, about 550mm x 550mm by 300mm in size, and apart from the hinges and latches, is made totally of lightweight composite material and is therefore easy to place and move about literally anywhere.
Solar cookers are available with ease online and increasingly in local markets too. The biggest benefit we have found is that it liberates us from the kitchen, as food laid out to cook does not get burnt, because temperatures do not rise beyond a moderate cooking level. This is one product where, hopefully, local unbranded options will do much better than costlier branded types. Simple rule - if you get even half a day's sun for half the year, then you will recover your investment in short time. Not to mention that you must have access to a roof, balcony or yard, which gets at least two-three hours of Sun on sunny days.
The previous problems of birds pecking at the solar panels have been solved by using full reflecting surfaces. However, within Indian conditions, we may need to see solar cookers with drain plugs to remove condensation that forms inside the cooker at times. Right now, we just hold it upside down, and then wipe it dry.

Any links for online purchase?

Many thanks for interesting article on solar cooking. It would be a great
feat if Government machinery is used to arrange for actual exhibitions in various cities in which the manufacturers can present their models. If they can also make available details of after sales service it would give an assurance that aam aadmi can buy and use these, and approach them for assistance if and when needed.

Can we ask mr Malik to identify the maker, if he is totally satisfied with the performance? Is this the first one he tried? or there similar ones (capacity wise) available in the market?

In the same way, I hope soon some solar panel manufacturer comes out with a small prototype unit that individual houses/flats can buy and plug the system to the main lines so that power generated is used at home as well. It is not easy for everyone to spend Rs 2/3 lakhs to make initial investment because the economies of scale, relating to the actual monthly bill currently paid, may not permit such a purchase!

Such simpler units can then be clubbed together in a given area and generate power for use themselves and release the balance to the central grid...

In response to points raised by Dr. Ramdas -

# There is hardly any after sales service required for a solar cooker. A wet cloth to wipe the reflecting surface; and the rest is like a suitcase.

# The manufacturer's name is "Rohitas Electronics" the product is "Tulsi Solar Oven" and their website is at -http://www.tulsisolarcooker.com/

# I have done a few articles on solar power at MoneyLife in the past also. It is really sad that government policies in India appear to favour "big solar" but then economies of scale are tipping things in favour of "micro-small solar".

# This aricle from the Economist explains how Africa is racing ahead with solar power.

# In India, the Armed Forces are making major strides in solar power solutions.

I hope this helps explain things.

Tks Veereshji,
Just shifted to a terrace apartment and would love to implement your recipe.

Cold Products Pay Millions for Misleading Consumers
Unproven cold prevention and treatment claims are nothing to sneeze at
There is no cure for the common cold but that has not stopped several over-the-counter products from claiming to treat the viral infection so common this time of year. 
But false and deceptive advertising carries a price. Here are a few recent cases where marketers were taken to task for making unsubstantiated claims about their product’s ability to both treat and prevent a cold.
They are not to be sneezed at:
Airborne — In perhaps the largest settlement of its kind, the makers of the multivitamin and herbal supplement Airborne agreed in 2008 to pay $30 million to settle a class-action lawsuit over the alleged false advertising of its “miracle cold buster.” The FTC alleged there was “no competent and reliable scientific evidence” behind Airborne’s claims. Sales of Airborne products exceeded $300 million from 2005 to 2007, according to the agency’s complaint. 
Rite Aid — The following year, national pharmacy chain Rite Aid agreed to dole out $500,000 in customer refunds to settle FTC charges that it deceptively advertised its “Germ Defense” tablets and lozenges, making germ-fighting claims backed by inadequate evidence. The FTC said $4.5 million worth of Germ Defense products flew off the shelves from 2005 to 2008. 
CVS — Just a few months after the Rite Aid resolution, national retailer CVS entered into a similar $2.8 million settlement with the FTC over the alleged deceptive advertising of its AirShield products. The FTC said AirShield was marketed as comparable to Airborne and like Airborne, the agency said AirShield lacked the science to support claims to boost the immune system or prevent colds. Sales of AirShield topped $14 million from 2005 to 2008, the FTC said. 
Zarbee’s — Dietary supplements cannot make the same health claims as drugs, which have FDA approval. In 2014, the FDA said that much to the makers of the dietary supplement Zarbee’s, warning in a letter that cold treatment and prevention claims on the product’s website and social media pages needed to go because Zarbee’s is not an FDA-approved drug. One of the challenged claims that still appears on the site states that Zarbee’s provides “proven congestion relief.” 
Cold-EEZE — A class-action lawsuit filed in 2014 alleges that the makers of Cold-EEZE have violated a 1999 FTC consent agreement that prohibits the company from making health claims without “reliable scientific evidence.” An FTC complaint alleging that the manufacturer of Cold-EEZE made unsubstantiated cold treatment and prevention claims on QVC, a national cable home-shopping network, prompted the consent agreement.
Dietary supplements and homeopathic remedies like the OTC cold products above are not reviewed by the FDA. Consumers should proceed cautiously and conduct due diligence before grabbing one of these products from off the shelf.
