Refrigerators are major home energy consumers. Here is a new technology that is developing as solar cells become more efficient.Paul Ridden of GizMag.com reports:
"A fridge that positively thrives in direct sunlight might seem a bit of a strange idea, but if you find yourself in a baking hot country where keeping your medical supplies cool and fresh could mean the difference between life and death, or you just want to sell some chilled refreshments to passers-by, then you need a portable, stand-alone chill solution. Industrial Insulation Systems (IIS) has developed a solar powered fridge/freezer which can be tailored to meet the needs of these off-the-grid scenarios.
The custom, made to order IIS solution will maintain temperatures as cold as -5F (-20C) for at least 24 hours between charge, but with the (up to) 400 amp hr battery capacity and the solar panels working in harmony and regular exposure to sunlight, you should be able to go completely off-grid indefinitely."
