Vacuum panel insulation, liquid hydrogen fuel cells and lithium batteries. All this will be possible when the entire state of Nevada is covered with Chinese solar panels. Can you imagine cooling a forty foot rig with 5,000 BTU's of refrigeration? And using the heat generated to gassify the hydrogen. Thermoelectric induction cookstoves.
And regarding vacuum. Sound cannot travel through vacuum. I just got an email from Shenzang China announcing the launch of a 12 volt four hundred watt CREE light bar. Supposed to equal the light given by a thousand watt HID fixture. For search and rescue I guess. I had to make sure the four hundred watts was not deceptive as in "Equal to". Nope, the puppy has a 35-amp draw.
