car news for india image
I've recently read an article "Viva-Lite | The benefits of Daylight lighting" from squidoo. Does the full spectrum lamps have any relevance in countries like India where sunlight is abundant, through out the year?
Answer
1. It might appear that in a country like India this question is less relevant. But in fact it is not so. When you observe people living in countries where sunlight is abundant, they mostly try to avoid sunlight wherever possible - due to a number of reasons of course, one simply may being not to get any more tanned than necessary.
2. In developing countries at least the way while going to work used to be somewhat outdoors, but since this is changing and more and more people are working in offices, going to work by car and all rooms being fully equipped with AC, we cannot ensure that receive their daily optimum dosage of sunlight.
3. It is reported in various news and media channels for example in India, that people are getting more and more depression, especially in cities. This was unheard of in the past. Reason for this need to be studied more and certainly stress plays a major role, but there are chances that subtle things like less exposure to sunlight (which was abundant and natural so far) are also reasons that support such mental diseases.
In conclusion I would suggest that all offices, hospitals and schools around the world - being in sunlight rich or sunlight poorer countries - should be equipped with the best possible lighting of which full spectrum light still is the most natural choice.

Can a decent electric car or truck conversion be made using a 9.8kw gas/generator with batteries?
Philip
I read about it in an old Mother Earth news (1993?) The car was mainly powered by the gen. The batteries would only kick-in for hills, boost of power, etc. I am interested in this design, anyone know if it works well? Can I use a 480volt 3ph gen-set to power motor/Drive for more efficiency/power? I already know about the volt,prius,leaf.
Answer
On the web a few years ago, and this was ultimately sold on Ebay; was a Geo metro that was modified to run strictly on a 10 horsepower/7500 KW Lister clone/"Listeroid" Diesel engine imported from India.
On a level surface, it could get to 55 Mph/88KPH if you did not mind the slow acceleration. Going up hill it would slow down considerably. They ran it with WVO and did better than 75 MPG.
If you stick with a lightweight car, or light small pickup truck like a Chevy Luv, or similar vintage Mazda or Datsun, you could see reasonable results. You would have tradeoffs to consider as well, since batteries are heavy.
Options to consider for your use- Aircraft starter generators for the drive motors. Diesel as your fuel for your genset. If you opt for one that has limited external monitoring circuitry, that will lighten the load some.
