Tesla cars do a little better than that and for considerably less cost.  I am sure that a lunar base could charge a lunar rover to the point of operating for a couple of hours while shining a nice light on the terrain.  We may even be able to install portable light stands or permanent lights in areas that are continually worked.  

Another problem to solve are the bases that will be in night for two week intervals.  

LocalFluff, 
I like your linked video.  I think they showed us that in school, and I wondered why they didn&#039;t just send another ship when the sun was shining on the far side of the moon.  In the case of the lunar poles, there are places where the sun never shines.  Power can be obtained at the poles by locating solar arrays on rises where the sun shines a vast majority of the time.]]></description>

					<description><![CDATA[@mpthompson,
If the area is photographed once in proper lighting, and this is converted to a virtual view in the goggles of the astronaut walking in it later, seeing the topography in the shadows on a virtual screen. Just a little complication compared to Apollo.

Walking or driving around in shadows with good active lighting requires power. Either in batteries, in a nuclear power, or cables or beams from power stations. And the worlds largest interplanetary rover, Curiosity that costs $3B, has only 1/6 of a horse power electric power. Maybe economic lights and visual light amplifiers can take care of it.]]></description>

					<description><![CDATA[&lt;i&gt;Lunar poles are interesting for ISRU, but one thing that makes in difficult for astronauts are the long shadows. Without an atmosphere shadows are very sharp, one is blinded by the lit up parts of the ground and cannot see if there are holes or boulders in the shadows. &lt;/i&gt;

Wouldn&#039;t a bright flashlight or floodlight on a vehicle take care of that?]]></description>

					<description><![CDATA[Looks like a very difficult landscape to traverse. Sand dunes to get stuck in, steep ravines, boulders everywhere. And Mars&#039; atmosphere is too thin to let anything fly in it, except for maybe the tiniest short range drone.

Robert seems to like spelunking and trekking in harsh landscapes. How much harder would it be in a group of three, with space suites and near certain death if it is damaged, with no prior ground knowledge of the place, with no support other than the radio?

Lunar poles are interesting for ISRU, but one thing that makes in difficult for astronauts are the long shadows. Without an atmosphere shadows are very sharp, one is blinded by the lit up parts of the ground and cannot see if there are holes or boulders in the shadows. And the constantly change as the Sun slowly moves 14 degrees a day. One wouldn&#039;t recognize the local landscape from one day to the other. Now, maybe visual aids can fix that, Pokemon style.]]></description>

					<description><![CDATA[The picture isn&#039;t loading for me right now so I have to wait to get a detailed look.

IIRC on Earth, when you see cuts at different levels like that it is from different events. Sand is easily blown around but it would be cool to know if there are ripples from larger sediments.]]></description>
