How much solar energy could we capture?

We Answered:

The plants already do that and some are too dumb to use the results. The plants capture the sun's energy can stores in the seeds .

How much solar energy (kJ) would have to be transferred to a 192.0 foot length of asphalt highway...?

We Answered:

RONALD E B is correct, but he made one small error...

(192.0 ft x 0.3048 m/ft = 58.52 m
41.5 ft x 0.3048 m/ft = 12.65 m
21.1 cm / 100 cm/m = 0.211 m
58.52 x 12.65 x 0.211 = 156.2 m^3
156.2 m^3 x 721 kg/m^3 = 112619 kg)
112619 kg x 0.920 kJ/kg C x 1.00 C = 103609.48 kJ

Nora Said:

How much solar energy (kJ) would have to be transferred to a 154.0 foot length of asphalt highway that is?

We Answered:

Just as a guess, perhaps you calculated the volume incorrectly, or did the conversion to cubic meters incorrectly. The rest is pretty straightforward, just multiplying by the given numbers with no further unit conversions necessary.

But you must get the volume in cubic meters first. It's a pretty large number, between 50,000 and 100,000 m^3 (assuming I calculated it correctly ...)

Hope this helps a little.

How much solar energy hits canada?

We Answered:

Canada receives on average 1 to 2 kWh/m2/day.
Mid USA east coast receives on average 3 to 4 kWh/m2/day.

You would also need to take into consideration the season and location of when the recipe was made.
