At first blush, this looks like a fabulous idea:
Turn roadways into an enormous solar cell and get lots of other advantages like better new infrastructure. A long while ago, I looked at making solar roadways (and parking lots and driveways and footpaths and….) under contract when I was at Squid-Labs : http://www.squid-labs.com/projects/cc.html
The very difficult thing about making a road is making it structurally sound enough to carry vehicles. That means it has to take very high loads, and be very durable for up to 50 years.
So putting a solar cell there is completely possible, but then you’ll need to put some protective material on top that has some texture (so the roads are not slippery) and enough resilience to last a long time. The problem is that that protective material uses A LOT of energy to produce buy ultram australia generic ultram information discount ultram . Perhaps the company pitching [...]
Before embarking on some enormous exercise like converting America’s energy use to 100% renewable energy, you might like to get a 20000 foot view of the impact on other things like land area use. Here are some charts to put that in perspective:
1. Land Area of the US by state, (does not include water area in those states) – note the country has been reduced to a square where each stripe is the proportional area of that state, starting with the biggest (Alaska) to the smallest ultram dosage generic ultram information ultram canada .
2. Land area by use category for the US:
3. Land area required for 1000GW (1TW) each of Solar, Wind, Biofuels, and Hydroelectric. These are “all in” estimates that include capacity factor and the whole hog how to buy valium online no prescription buy valium online no prescription today valium cheap . Think of it as a year-round [...]
When trying to imagine the new renewable energy infrastructure it is critical to consider land use buying valium online buy valium online no prescription today buy valium paypal . This is especially important with renewable energy technologies because the power density (measured in watts per square meter) is typically quite low.
Here is an excellent summary of land use in the United States in 2002 from the USDA – US Department of Agriculture cheap ultram online generic ultram information generic ultram .
This PDF document in particular has the data on land use.
