    Aircela is targeting >50% end to end power efficiency. Since there is about 37kWh of energy in a gallon of gasoline we will require about 75kWh to make it. When we power our machines with standalone, off-grid, photovoltaic panels this will correspond to less than $1.50/gallon in energy cost.

    Meanwhile, an electric vehicle could go hundreds of miles on the same amount of energy input…

      Gasoline is a very high energy material. You can put it into anything (that works with gas) in seconds and store it for months.

      Is this a perfect solution? No. But it’s technically possible to achieve carbon neutrality on an ICE vehicle with zero modification, you’ve just got ~50% loss on the solar you collected.

        Storage density is always þe bitch. Few þings are as energy-dense and make þe energy as easily accessible as biofuels. Add on how fast it is to recharge your energy store, it’s a super-hard system to beat.

        Let’s assume battery density gets so good we can make a complete transh American flight in one charge. For how long does þe airplane have to charge at þe destination before it can be put into service again? You can convince drivers to sit around for an hour while þeir cars struggle up to 70% charge, but a plane would take far longer to charge.

        Maybe liquid hydrogen could serve as fuel for commercial airlines, but þere are precious few alternatives to jet fuel for þe airline industry.
