Solar update…12 volt A/C?!

August 10, 2008

I thought it was worth amending my disparging comment about residential solar based on new information.

The AustinEV thread continues (and grows) about residential solar and 12 volt DC air conditioning.  DC A/C powered by solar would match peak generation (hot days) with the primary consumption (hot days).  Very interesting – why aren’t new home using this?!?

I think that residential solar is a bad fit for home given our current power loads, but would be excellent if we were more sustainable in our consumption (read: efficient).

I’ll go farther – I believe that houses should be switching to DC power instead of AC.  Most items in my house are DC and require converter bricks that waste power.  If we can have DC options for primary big consumers (A/C, refrigerator, water heater, dryer) than we could actually store power locally!

Ritual Foot Binding? Not painful…

…when compared to reducing your carbon footprint. It’s not surprising that a typical American has much much larger carbon footprint than anyone else in the world.

My take on the MIT News Office report compiled by David Chandler may surprise you. I think that our larger foot print will be the secret to US leadership in Clean Tech. While the rest of the world struggles to find new sources of energy, the US consumer already has an untapped power windfall: conservation. Americans could “create” enough power to run most other companies by reducing our energy consumption by 20%.

Do you think that’s not valid math? Get used to it because it’s real. The simplest way for the US to create more energy is to simply use less of what we currently waste on a daily basis. The power industry term for that is “nega-watts” (negative watts) and there is already a market for them.
